Return value in python function

Question

import urllib,re

def getver():
    url='https://github.com/Bendr0id/xmrigCC/releases'
    website = urllib.urlopen(url)
    html = website.read()
    links = re.findall(r'(?<=<a href=")[^"]*\bgcc-win64.zip\b', html)
    link=links[0]
    version=link.split('/')
    ver0=version[5]
    return ver0
getver()

I've tried to run the code but it doesnt output anything,instead when I replace return with print it prints out the correct answer which is 1.5.2 . What am I doing wrong?

Answer 1

将最后一行更改为：

print(getver())

Answer 2

You have been fooled by the interactive interpeter's friendly habit of printing out the results of any bare expressions you enter.

This does not happen when you run a program, so you need to ensure you output values specifically by using the print statement.

This is specifically mentioned in a rather obscure portion of the Python documentation dealing with the language's grammar.
