I'll weigh in with a mini- (and unasked-for-) lecture here: this is often the point at which someone says "boy, I wish Python were strongly typed, so things didn't change types in flight". But in fact, the list didn't change types, it's still a list. In fact we even know where that list is: it's the first element of that tuple you ended up with. The _name_ you gave to that list carries no typing meaning, however (although you can give it type hints that an external tool could use to warn you that you are changing something). So you have somewhere given that name to a completely different object, a tuple which contains your list and another element. So clearly what you're looking for is the place that happens. So here's a sketch of how you might use type hinting to find this, to bring it back to something practical: === types.py: from typing import List, Tuple a: List[str] = [ '/a/path', '/b/path', ] print(type(a)) print(a) a = (a, '/c/path') print(type(a)) print(a) === this works just fine: $ python3 types.py ['/a/path', '/b/path'] (['/a/path', '/b/path'], '/c/path') === but a hinting tool can see a possible issue: $ mypy types.py types.py:10: error: Incompatible types in assignment (expression has type "Tuple[List[str], str]", variable has type "List[str]") Thanks for this.

[Tutor] problem with creating paths
I can now add to my previous email the following observation.

[Tutor] problem with creating paths
I am a novice (at programming). I use MAC OS 10.13.6 Anaconda. Python 3.5.4 Spyder 3.5.6 I have just re-written a moderately complex program (a Class) on the advice of Alan and Steven. The rewriting proved to be very useful. The working program uses instances of the Class with User chosen parameters. The output data seems correct to me. So I then began redoing all the tests. The first Methods tested gave OK. But I have just started testing a new Method and I get a Universal error in my tests. It says that the output file is already present. These files (paths) are correctly deleted by the 'teardown' Method, when only the earlier portion of the program is tested. But are not deleted with the last method tested. After searching I have found this unexpected output illustrated in the copy-paste below. test The type of the paths is: The values of the paths are : ( [ '/Users/sydney/AnacondaProjects/reproduction/Current_Version/Results/', '/Users/sydney/AnacondaProjects/reproduction/Current_Version/Results/20181017D', '/Users/sydney/AnacondaProjects/reproduction/Current_Version/Results/20181017D/A_POCI_Input_Data', . . . . '/Users/sydney/AnacondaProjects/reproduction/Current_Version /Results/20181017D/B_Cycle_Zero/Text_Files', . . . '/Users/sydney/AnacondaProjects/reproduction/Current_Version/Results/20181017D/C_Final_Results/Plots/Population_Data/Ratios'], '/Users/sydney/.Trash/20181017D/B_Cycle_Zero/Text_Files') There are two items that are 'wrong' in this output. 1. The property 'paths' is defined in the program as a list and the items are added using paths.append(), yet the test says that when tested it is a tuple. 2. The tuple arises by the addition of the last entry in the file, AFTER the closing bracket of the list which is the first item in the tuple. When I test the length of 'paths' I get a value of 2! I apologise for the lengthy explanation, but I am at a loss. I have looked for an error that might have added an item as a + and I find nothing. The character of the final item is also puzzling to me. I would much appreciate any guidance as to how I should search for the fault or error.

On 21/09/2018 00:01, Oscar Benjamin wrote: Sydney wrote and Alan forwarded: I have, I suspect, an elementary problem that I am too inexperienced to resolve. I have two numpy arrays, each representing the values of a specific property of a set of cells. Now, I want to associate the two values for each cell, that is for each index of the numpy array. But I want to associate them ROUGHLY, that means, APPROXIMATELY, so that there is a weak, linear correlation between the values representing one property and the values representing the second property of each individual cell. Up to now I have used the following procedure. I have divided each population of values into four segments based on the value of the standard deviation thus. 1. values > mean + 1 std (sigma) 2. values > mean but < mean + 1 std (sigma) 3. values < mean but > mean + 1 std (sigma) 4. values < mean + 1 std (sigma). Then I randomly select a value from group 1 for the first property and I associate it with a randomly selected sample of the second property from its group 1. And so on through the total population. This gave me a very rough linear association between the two properties, but I am wondering whether I can do it in a simpler and better way. Hi Sydney, I feel like I would definitely be able to solve your problem if I understood what you're talking about (I'm sure others here could as well). Please don't be put off by this but I don't think you've explained it very well. Perhaps if you give an example of what the input and output of this operation is supposed to look like then you would get a response. The example might look like: I have these arrays as input: property_a = [1, 6, 2, 4] property_b = [6, 3, 4, 6] Then I want a function that gives me this output associated_values = myfunction(a, b) associated_values [1, 3, 5, 2] Some explanation why you want this, how you know that's the output you want, and what any of it means would likely help... If you already have something that does what you want then it would make sense to show it but if your code is complicated then please try to simplify it and use only a small amount of data when showing it here.

It's not so much that they have a VCS but that they integrate with an existing VCS. So they will typically have menu options for checking in/out a file or locking/unlocking it. Typically you can configure which VCS they use from a list of common options, in some cases you can define the command line to use for each menu action. vim, emacs, Eclipse, Netbeans, VisualStudio etc all support VCS to varying degrees. But you still need to install and configure a VCS engine such as CVS, SVN, Hg or git etc. Thanks, that clarifies it for me. I shall learn to use GIT.

I have not met this advice from Steven D'Aprano before, so I have some questions. I have constructed a program which has a parent class and a child class and I have them in two different files. I import the parent class into the child class and create instances with the child class. This works fine. But, would it be better to have both classes in one file? Would then the child class 'know' that the parent class is in the file? And further. I have a function which sets up all the suitable data structures into which this function will put the information supplied by the user. I import this file too into both the parent and the child class. Would the instances with which I actually work, 'know' that this function is there if it is simply present in the same file? -- Sydney ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I am not finished yet, but there are already nearly 400 tests. The tests run and return OK. [After cleaning up many silly mistakes that I made.] However, now, when I run the tests (Unittest) I get the following warning: lib/python3.5/unittest/case.py:1092: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison if member in container: ...

My sub-class is constructed as follows: import sys import random import numpy as np import pylab import copy import Population_InitV8 as POCI import Population_ProductivityV24 as POCWP line 27 : class SimulateCycleZero(POCWP): line 28 : def __init__(self, dirname_p): The program follows on from this.

[Tutor] unittest difficulty
I am learning to use unittest. I have written a program that runs as it should. 247 tests give me a satisfactory answer. I have now added one more test and I get an error which I do not understand. The two relevant tests are: def test_type_capitalsadvanced(self): self.assertEqual(type(self.capitalsadvanced), numpy.ndarray) def test_zero_in_capitalsadvanced(self): self.assertIn(self.capitalsadvanced, 0.0) The error message is: Traceback (most recent call last): File "/Users/sydney/Capital/Capital_with_productivity/Current_Versions/testPOCWP_V2.py", line 320, in test_zero_in_capitalsadvanced self.assertIn(self.capitalsadvanced, 0.0) File "/Users/sydney/anaconda/lib/python3.6/unittest/case.py", line 1077, in assertIn if member not in container: TypeError: argument of type 'float' is not iterable Final output from the tests is : Ran 247 tests in 1.179s FAILED (failures=9, errors=1) The failures all arise from a 'nan'. It is this problem that I am trying to resolve. My problem is that the first test tells me correctly that the object capitalsadvanced is a numpy.ndarray. But the second test error message says it is a float. I should add that the program creates the initial data set by making use of the random function which is given a mean to work with. Thus each test run will be with different input data. But repeated tests show the same errors. Any guidance will be very welcome.

Here is the section. fiftypencecoins = int(input(how many 50p coins do you want to insert or press 'e' to exit : )) if fiftypencecoins == 'e': break else: currentmoney += fiftypencecoins * 5/10 print(your newly updated credit is £ + str(currentmoney) + 0) Is this Python 3 or Python 2 ? May be that's not relevant. So anyway, if you want to see whether the int() function will be successful on your input, you need to check whether the input constitutes of only digits.

To the best of my knowledge, yes to both of your queries. Once you have the element you want to process, you can make use of the type converting functions (int(), float().. ) and use them appropriately. 3. Are there defined procedures for doing the required processing? If you meant conversion functions, int() and float() are examples of those. You of course (most of the times) have to make use of string manipulation functions (strip(), rstrip(), etc) to extract the exact data item you might be looking for. So, they would be the building blocks for your processing functions. I hope that makes some things clear. -Amit. Yes, Thanks. This is now quite clear.

Is it the case that ALL imported data from a file is a string? Assuming you mean data read from a file rather than modules imported using 'import' then the answer is 'it depends'. Most files are text files and the data is stored as strings and therefore when you read them back they will be strings. You then convert them to the native data using int(), float() etc. Some files are binary files and then the data read back will be bytes and need to be decoded into the original data. This is often done using the struct module. Either way if you use the Python read() operation on a file you will get back a bunch of bytes. What those bytes represent depends on how they were written. How they are interpreted is down to the programmer. 2. Does this therefor imply that said data has to be processed appropriately to generate the data in the form required by the program? Yes, always. 3. Are there defined procedures for doing the required processing? Yes, for the standard types. For custom types and arbitrary binary data you need to find out what the original encoding was and reverse it. HTH, Thank you Alan, That was most useful.

Hi there,
I'm trying to create a plain text file called hello.py
with the following text :
print('hello world')
raw_input('Press any key to continue')
I'd then like to run this program with Python Launcher on
a Mac.
I'd lke to use Xcode as my text editor. Once I have Xcode
open, which template should I use to input the text ?
I don't think there is a file type of Python that you can
create from Xcode.
Just curious, why would you want to use XCode as a Python editor?
Thanks,
*Dustin Guerri*

Re: [Tutor] First Python Test
Text Wrangler is a free, cut-down version of BB-Edit, I think.

Re: [Tutor] First Python Test
Dear Aurelien, Would you please explain how one installs GNU Emacs on a MAC using OS X v10.6. I cannot find a binary package. The GNU site seems to me to have only source code packages.

Re: [Tutor] First Python Test
You are correct, of course. OK. So Bluefish is the Free open-source GNU editor and it is suitable for Python. We will have a complete menagerie soon. Thanks.
