help using functions from other files

[lga13]

Can anyone assist with this, I am trying to import a calculation from maths.py into my file main.py, I think i have it set properly to pull the calculation through by using

 from maths import median

to get the median function to come over to main.py

I need to find the median of a list of numbers and have it print out the median.

this is my code for the calculating the median

def median(alist):
    """ Calculates the median of a list of numbers.The list must not be empty."""

    number_of_values = len(alist)
    sorted_list = sorted(alist)

    # Two cases, depending on whether the number of values is odd or even.
    quotient = number_of_values // 2
    remainder = number_of_values % 2
 
    if (remainder == 1):
        result = sorted_list[quotient]
    else:
        result = (sorted_list[quotient - 1] + sorted_list[quotient]) / 2
    return result

how can i make this run so that it will give me the median in main.py?

any help and advice would be great - I'm using 3.7.0 if that helps at all.

It should work as long as maths.py and main.py is in same folder.
Have you tried it,do you get error?
Test main.py:

from maths import median

lst = [1, 2, 3, 4, 5]
print(f'Median of list is <{median(lst)}>')
print('-------------')
# Also help() work as you have docstring in function
help(median)

Output:
Median of list is <3>
-------------
Help on function median in module maths:

median(alist)
    Calculates the median of a list of numbers.The list must not be empty.

Thanks for the help that is working as expected!

there was no error message but if i did the likes of print(x,y,z) it wasn't doing anything, can you explain what the f on this line does?

print(f'Median of list is <{median(lst)}>')

can you explain what the f on this line does?

f-string is the new string formatting(new in 3.6).
format() we have had since 26..
Example.

# older way
>>> first_name = "Eric"
>>> age = 30
>>> print('Name is:{} Age is:{}'.format(first_name, age))
Name is:Eric Age is:30
>>> 
>>> # The new way
>>> first_name = "Eric"
>>> age = 30
>>> print(f'Name is:{first_name} Age is:{age}')
Name is:Eric Age is:30

>>> print(f"Sammy has {4:4} red and {16:16}! blue balloons")
Sammy has    4 red and               16! blue balloons
 
>>> # f-strings support any Python expressions inside the curly braces
>>> name = 'f-string'
>>> print(f"My cool string is called {name.upper()}.")
My cool string is called F-STRING.
 
>>> a, b = 5, 7
>>> f'{a}/{b} = {a/b:.2}'
'5/7 = 0.71'
 
>>> for word in 'f-strings are awesome'.split():
...     print(f'{word.upper():~^20}')
~~~~~F-STRINGS~~~~~~
~~~~~~~~ARE~~~~~~~~~
~~~~~~AWESOME~~~~~~~
