PythonPath / sys.path
Hi All My first post (repeated) I am having a problem with PythonPath / sys.path I have a dir where I keep all my current work, but I can't seem to add it to PythonPath / sys.path When I try to import one of my modules I see >>>import My_Working_File Traceback (most recent call last): File "", line 1, in import My_Working_File ImportError: No module named 'My_Working_File' I have tried adding my dir in registry to the existing PythonPath [HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\PythonPath] @="D:\\Shades\\Tools\\Python\\Lib;D:\\Shades\\Tools\\Python\\DLLs" that did not help, I tried adding PYTHONPATH as an enviramental variable, that also had no effect (I did re-boot after these two tests) If I go to the editor window and run (F5) any of my modules then I can >>> RESTART >>> >>> import My_Working_File >>> without error I can also (from a fresh start) >>> import sys >>> sys.path.append(r'D:\Shades\Tools\Python\MyWork') >>> print(sys.path) ['', 'D:\\Shades\\Tools\\Python\\Lib\\idlelib', 'D:\\Shades\\Tools\\Python\\python34.zip', 'D:\\Shades\\Tools\\Python\\DLLs', 'D:\\Shades\\Tools\\Python\\lib', 'D:\\Shades\\Tools\\Python', 'D:\\Shades\\Tools\\Python\\lib\\site-packages', 'D:\\Shades\\Tools\\Python\\MyWork'] >>> import My_Working_File >>> I don't really want to go this route every time I start work, and more to the point I will need (to learn how) to add dir's to the path at times I did search the net for an answer but only got what I had already tried any pointers what I'm doing wrong (other than using windows '->) Grizz -- https://mail.python.org/mailman/listinfo/python-list

I must have slept a while Python 3.4.10 (default, Jul 14 2019, 14:41:03) [MSC v.1600 32 bit (Intel)] on win32 Actually I did have 3..4.3 when I asked the question (first time) because I could only find 3.4.10 as src and did not feel I was able to compile it with any certainty ;->) I have since moved up (a little) so only ~4 years old, I then updated pip from 9.x to 19.1 reason its an old version is it's an old PC (XpPro), if I start to get passable at this I will try it on my Ubuntu box which is running 22.04 (latest LTS) and 23.04, (23.10 daily builds soon) I took a look and it seems I "may" have to play a little to get IDLE on (if it's not in the normal repo's) I seem to have managed to sort "PythonPath / sys.path" the environment variable is working, so I can now import my_work without any other hassle, which is good, now I find that some of the files which worked a treat from GUI, Editor (F5) or terminal but don't do the same once saved and imported later, I'm sure it's me, I have come from VB/VBA, Delphi and a (very) little C++, and am still working through the python tutorial, trying not to skip ahead (ok I did skip "Hello World" :->) so I may end up asking some (senior moment) newbie questions, I will try hard to work it out myself first Thanks to all who got me thus far Grizz -- https://mail.python.org/mailman/listinfo/python-list

Silly (maybe) question re imported module(s)
Morning All I'm working through the tutorial and running / saving work that I wish to keep and build on, most times I can save and (re)import later with no difference to when typed in console or editor and run with F5 (which saves before it can run) But sometimes saved work (albeit small) when imported does not work any longer I assume I have missed something, any pointers to what/how/why please -- https://mail.python.org/mailman/listinfo/python-list

Newline (NuBe Question)
Hi & thanks for patience with what could be simple to you
Have this (from an online "classes" tutorial)
--- Start Code Snippit ---
students = []
grades = []
for s in geographyClass:
students.append(geographyStudent(s))
for s in students:
grades.append(s.school)
grades.append(s.name)
grades.append(s.finalGrade())
if s.finalGrade()>82:
grades.append("Pass")
else:
grades.append("Fail")
print(grades)
--- End Code Snippit ---
I have extended (from tutorial) it a bit, I would really like to have a newline
at end of each record, I have searched (and tested) but cant get "\n" to give a
newline, I get "Mydata\n"
Do I need to replace "append" with "print", or is there a way to get the
newline in as I append to list?
Thanks again

True, I onlt went that way when my (vain) attempts to add a newline any other
way, my usual language is VB/VBA, Delphi or C++ at a push, so I'm really a nube
here

that gets closer (sort of) my old code gave on long (only 5 records so far)
list,
['Example High', 'Mary', 89.6, 'Pass', 'Example High', 'Matthew', 76.5, 'Fail',
'Example High', 'Marie', 80.4, 'Fail', 'Example High', 'Manuel', 79.6, 'Fail',
'Example High', 'Malala', 98.9, 'Pass']
your code gives one tall column,
Example High
Mary
89.6
Pass
Example High
Matthew
76.5
Fail
Example High
Marie
80.4
Fail
Example High
Manuel
79.6
Fail
Example High
Malala
98.9
Pass
my ideal one row for each student (this I have edited manually)
Example High, Mary, 89.6, Pass
Example High, Matthew, 76.5, Fail
Example High, Marie, 80.4, Fail
Example High, Manuel, 79.6, Fail
Example High, Malala, 98.9, Pass

I already jumped forward a bit (to python Classes)

for now I made a copt of code and altered to
students = []
grades = []
for s in geographyClass:
students.append(geographyStudent(s))
for s in students:
if s.finalGrade()>82: Result=("Pass")
else: Result=("Fail")
print(s.school, s.name, s.finalGrade(),Result)

I will look forward to them, may even go search ahead,

I copy-pasted the code direct from IDLE, (to avoid any other typo's)

I'll hive this a try (as a learning point)
