简单讲讲python中的os模块

import os
print(__file__)
print(os.path.dirname(__file__))

import os
print(os.getcwd())
os.chdir('c:\\')
print(os.getcwd())

import os
os.rename('a.txt', 'b.txt')

import os
folder = os.path.exists('c:\\windows')
print(folder)

import os
folder = os.path.isfile('c:\\windows')
print(folder)

import os
folder = os.path.isdir('c:\\windows')
print(folder)

import os
for k, v in os.environ.items():
    print(k, '=>', v)

import os
x = os.mkdir('c:\\newFolder')
print(x)

import os
x = os.makedirs('c:\\newFolder\\a')
print(x)
