python - 如何检查 os.makedirs 的参数？

Question

我使用此代码为用户创建文件夹:

work_path = '/tmp/'

os.umask(0000)
for i in user:
    if not os.path.exists(work_path + i):
        try:
               os.makedirs(work_path + i, 0777)

当我设置 work_path = '/tmp/' 时 - 我的代码工作完美。但是当我输入错误 work_path = '/tmp' 时，我没有得到预期的结果 )))

问题:如何检查我的路径是否有反斜杠，或者如何以其他方式创建文件夹？

使用os.path.join :

Join one or more path components intelligently. The return value is the concatenation of path and any members of *paths with exactly one directory separator (os.sep) following each non-empty part except the last, meaning that the result will only end in a separator if the last part is empty. If a component is an absolute path, all previous components are thrown away and joining continues from the absolute path component.

os.makedirs(os.path.join(work_path,i))

因此，在您的代码中加入路径一次，然后使用加入的路径:

for i in user:
    pth = os.path.join(work_path, i)
    if not os.path.exists(pth):
        try:
            os.makedirs(pth, 0777)
