python os,sys模块的常规使用

这是我经常使用的os，sys模块的操作

import os,sys


def osl():
    a = os.getcwd()
    print(a)

    b = os.listdir(a)
    print(b)

    c = os.path.abspath(__file__)
    print(c)


    d,e = os.path.split(c)
    print(e)
    print(d)

    f = os.path.dirname('D:\\code\\sss')
    print(f)


def sysl():
    a = sys.argv[0]
    print(a)
    # print(sys.path)

    BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

    print(sys.platform)
    print(sys.version)
if __name__ == "__main__":
    sysl()
