从命令行执行 Python 脚本会隐藏打印语句 [英] Executing Python Script From Command Line is Hiding Print Statements

问题描述

我知道这一定是一个非常基本的问题，但是，我已经尝试在整个 SO 中找到一个简单的答案，但找不到.

I know this must be a super basic question, however, I have tried finding a simple answer throughout SO and cannot find one.

所以我的问题是:如何从命令行执行 python 脚本，以便我可以看到打印语句.

So my question is this: How can I execute a python script from the command line such that I can see print statements.

例如，假设我有文件 test.py:

For example, say I have the file test.py:

def hello():
    print "hello"

如果我进入解释器，导入test.py，然后调用test.hello()，一切正常.但是，我希望能够只运行

If I enter the interpreter, import test.py, and then call test.hello(), everything works fine. However, I want to be able to just run

python test.py

从命令行并让它打印hello"到终端.

from the command line and have it print "hello" to the terminal.

我该怎么做?

谢谢！

更新:是的，抱歉，我的脚本实际上更像这样:

UPDATED: Yes, sorry, my script is actually more like this:

def main():
    hello()

def hello():
    print "hello"

还需要调用main()，还是自动调用?

Do I still need to call main(), or is it automatically invoked?

推荐答案

在文件末尾添加:

if __name__ == '__main__':
    hello()
