python 调用不同路径文件

文件材料：

A. file1.py 源文件

B. file2.py 源文件

C. folder1 文件夹

D. folder2 文件夹

1.同级目录文件路径

根目录	file1.py
	file2.py

 

 

#file1.py
#!/user/bin/env python
#coding=utf-8

import file2;
file2.g__main__();

#file2.py
#!/user/bin/env python
#coding=utf-8



def g__main__():
	print "start loop";

　　

2.上级目录调用下级目录文件

根目录	file1.py
	folder2	file2.py
		__init__.py

 

 

 

#file1.py
#!/user/bin/env python
#coding=utf-8

import folder2.file2;

folder2.file2.g__main__();

 

#folder2.file2.py
#!/user/bin/env python
#coding=utf-8

#folder2 文件夹下必须有__init__.py

def g__main__():
	print "start loop";

　　

3.当前目录调用上级文件

根目录	folder1	file1.py
		__init__.py
		file2.py

 

 

 

#folder2.file2.py
#!/user/bin/env python
#coding=utf-8

import sys,os
import_dir = "../"
sys.path.insert(0,import_dir)
import file1;
file1.g__main__();

 

#file1.py
#!/user/bin/env python
#coding=utf-8


def g__main__():
    print "start loop";

 

 

4.同级目录相互调用

根目录	folder1	file1.py
		__init__.py
	folder2	file2.py
		__init__.py

 

 

 

 

#folder2.file2.py
#!/user/bin/env python
#coding=utf-8

import sys,os
import_dir = "../folder1"
sys.path.insert(0,import_dir)
import file1;
file1.g__main__();

 

#file1.py
#!/user/bin/env python
#coding=utf-8


def g__main__():
    print "start loop";
