我想运行Module而不运行：
from ex import x
global x
call ex.py
y = x+2
print y
x=5*3
这是简化代码。如你所见，我调用ex.py并使用变量x。但是当我运行main.py时，ex.py也在运行。但我只想得到什么是x并在main.py中使用
import pygtk
pygtk.require20()
import gtk
import subprocess
from ex import x
global x

这就是整个代码，正如我所说，我想从ex：
获得“X”答案 0 :(得分：0)
正确的语法是
if __name__=='__main__':
ex()
编辑：为了更完整地回答，这是一个例子。
ex.py：
# some lines of code
print ("Hello World")
x=3*5
# A function
def mysum(a,b):
return a+b
# Protect execution
if __name__=='__main__':
print ("I am main")
print ("2 + 2 is %d" % mysum(2,2))
“Hello World”将始终打印，但只有在直接运行ex.py而不是导入时才会打印“我是主要”。
x可从导入中获得。
编辑2：使用问题中的完整ex.py代码：
#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk
global x
def foo():
response = dialog.run()
if response == gtk.RESPONSE_OK:
dialog.get_filename(), 'selected'
elif response == gtk.RESPONSE_CANCEL:
print 'Closed, no files selected'
x =dialog.get_filename()
print x
if __name__=='__main__':
# dialog related calls shall be protected against execution
dialog = gtk.FileChooserDialog("Open..",None,gtk.FILE_CHOOSER_ACTION_OPEN,
(gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,
gtk.STOCK_OPEN, gtk.RESPONSE_OK))
dialog.set_default_response(gtk.RESPONSE_OK)
foo()
dialog.destroy()
