main() 函数在运行脚本时不运行 [英] main() function doesn't run when running script

问题描述

#! /usr/bin/python

def main():
    print("boo")

当我尝试在 Python 3.3 中运行这段代码时，它什么也没做.没有错误或任何东西.怎么了

This code does nothing when I try to run it in Python 3.3. No error or anything. Whats's wrong

[tim@tim-arch ~]$ gvim script
[tim@tim-arch ~]$ sudo chmod 775 script
[tim@tim-arch ~]$ ./script
[tim@tim-arch ~]$ 

推荐答案

您仍然需要调用该函数.

def main():  # declaring a function just declares it - the code doesn't run
    print("boo")

main()  # here we call the function
