等价于Python中R的source()

问题描述

就像我们具有source()函数一样，可以在R studio中的另一个R程序中执行R程序，如何在另一个python程序中执行python程序?

解决方案

给出2个python脚本:first.py和second.py，从第二个开始执行第一个的通常方法是: >

first.py:

def func1():
    print 'inside func1 in first.py'

if __name__ == '__main__':
    # first.py executed as a script
    func1()

second.py:

import first

def second_func():
    print 'inside second_func in second.py'

if __name__ == '__main__':
    # second.py executed as a script
    second_func()
    first.func1() # executing a function from first.py

编辑:

• 如果愿意，也可以使用简单的execfile("second.py")(尽管它仅在调用名称空间中).
• 最后一个选择是使用 os.system 所以:
  os.system("second.py").

Like we have source() function to execute a R program in another R program in R studio, how do I execute a python program in another python program?

解决方案

Given 2 python scripts: first.py and second.py, the usual way to execute the first from the second is something in the lines of:

first.py:

def func1():
    print 'inside func1 in first.py'

if __name__ == '__main__':
    # first.py executed as a script
    func1()

second.py:

import first

def second_func():
    print 'inside second_func in second.py'

if __name__ == '__main__':
    # second.py executed as a script
    second_func()
    first.func1() # executing a function from first.py

Edits:

• You could also go for the simple execfile("second.py") if you wish (although it is only within the calling namespace).
• And a final option is using os.system like so:
  os.system("second.py").
