os.path.join()函数：连接两个或更多的路径名组件
如果拼接在后的参数中含有'\'开头的参数，将从'\'开头的参数开始，前面的参数均将失效，并且路径将从对应磁盘的根目录开始。
import os
import os
Path1 = 'home'
Path2 = 'develop'
Path3 = 'code'
Path10 = Path1 + Path2 + Path3
Path20 = os.path.join(Path1,Path2,Path3)
print ('Path10 = ',Path10)
print ('Path20 = ',Path20)
打印结果
Path10 = homedevelopcode
Path20 = home\develop\code
