I changed the file to this:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""Task 07: declaring a dictionary, creating a function,
return a funky total """
DATA = {2: 7493945,
76: 4654320,
3: 4091979,
90: 1824881,
82: 714422,
45: 1137701,
10: 374362,
0: 326226,
-15: 417203,
-56: 333525,
67: 323451,
99: 321696,
21: 336753,
-100: 361237,
55: 1209714,
5150: 1771800,
42: 4714011,
888: 14817667,
3500: 13760234,
712: 10903322,
7: 10443792,
842: 11716264,
18584: 10559923,
666: 9275602,
70: 11901200,
153: 12074784,
8: 4337229}
def iter_dict_funky_sum(data=DATA):
"""function that takes one dictionary argument declaring
a running total variable, extracting key/value pairs from
DATA simultaneously in a for loop, assigning and appending
the product of the value minus the key to the running total
variable and returning the total."""
funky = 0
for key, value in data.iteritems():
funky += value - key
return funky
however now pylint is returning:
task_07.py:36: [W0102(dangerous-default-value), iter_dict_funky_sum]
Dangerous default value DATA (__builtin__.dict) as argument
how can I pass the dictionary into the function, since pylint considers the
wway I'm doing it to be wrong?
the assignment specifications are:
#. Create a file named ``task_07.py``
#. Declare a variable named ``DATA`` as a dictionary object. Assign it a
set
of key/value pairs. This is example data for you to work with but you
may
create any dictionary of data provided it is at least 10 items long and
both keys and values are integers.
#. Create a function named ``iter_dict_funky_sum()`` that takes one
dictionary argument.
#. Declare a running total integer variable.
#. Extract the key/value pairs from ``DATA`` simultaneously in a loop.
Do
this with just one ``for`` loop and no additional forms of looping.
#. Assign and append the product of the value minus the key to the
running
total variable.
#. Return the funky total.
I'm sure I'm doing everything else right, I guess pylint just doesn't like
how I'm declaring the variable? Everything is returning perfectly regarding
the example data and it's returning amount.
