Question

python3输入文件路径，若没有，则自动创建文件夹与文件名，并读写文件？

Answer 1

import os

fullpath = "D:\\data\\text\\Test\\test1.txt"
paths, file = [], None
path = fullpath[:]
while file!='':
    path,file = os.path.split(path)
    if file:
        paths.append(file)

while len(paths)>1:
    path += ('' if path[-1]=='\\' else '\\') + paths.pop()
    if not os.path.isdir(path):
        os.mkdir(path)

with open(fullpath, 'w') as f:
    f.write('test:测试内容！')
