1.编写python脚本

[root@njmon python]# cat create_path.py 
#!/usr/bin/env python
import os
def mkdir_func(path):
    path = path.strip()
    path = path.rstrip("//")
    os.path.exists(path)
    isExists = os.path.exists(path)

    if not isExists:
        os.makedirs(path)
        print path+' create successfully.'
        return True
    else:
        print path+' path is already exists.'
        return False


def main():
    mkdir_func("/aaa")
    mkdir_func("/bbb")

if __name__ == "__main__":
    main()

2.假如/aaa和/bbb文件夹不存在http://www.cndba.cn/hbhe0316/article/106598http://www.cndba.cn/hbhe0316/article/106598

[root@njmon python]# python create_path.py 
/aaa create successfully.
/bbb create successfully.

3.假如/aaa和/bbb文件夹存在http://www.cndba.cn/hbhe0316/article/106598

[root@njmon python]# python create_path.py 
/aaa path is already exists.
/bbb path is already exists.
