os.path.join()函数:连接两个或更多的路径名组件
1.如果各组件名首字母不包含'/',则函数会自动加上
demo1
import os Path2 = 'home' Path3 = 'develop' Path4 = 'code' Path20 = Path2 + Path3 + Path4 Path30 = os.path.join(Path2,Path3,Path4) print ('Path20 = ',Path20) print ('Path30 = ',Path30)
输出:
Path20 = homedevelopcode
Path30 = home\develop\code
2.如果有一个组件是一个绝对路径,则在它之前的所有组件均会被舍弃
demo2
import os Path2 = '/home' Path3 = 'develop' Path4 = 'code' Path20 = Path2 + Path3 + Path4 Path30 = os.path.join(Path2, Path3, Path4) Path40 = os.path.join(Path3, Path2, Path4) print('Path20 = ',Path20) print('Path30 = ',Path30) print('Path40 = ',Path40)
输出:
Path20 = /homedevelopcode
Path30 = /home\develop\code
Path40 = /home\code
3.如果最后一个组件为空,则生成的路径以一个'/'分隔符结尾
demo3
import os Path2 = 'home' Path3 = 'develop' Path4 = '' Path20 = Path2 + Path3 + Path4 Path30 = os.path.join(Path2, Path3, Path4) Path40 = os.path.join(Path3, Path2, Path4) print('Path20 = ',Path20) print('Path30 = ',Path30)
输出:
Path20 = homedevelop
Path30 = home\develop\
