How to create a directory with intermediate directories in Python?

The "mkdir -p" function in Python [duplicate]

In Python, how to implement something similar to the shell command "mkdir -p" "Function? Hoping for a solution that doesn't rely on system calls and has a code length of less than 20 lines.

Solution

For Python ≥ 3.5, use pathlib.Path.mkdir:

<code class="python">import pathlib
pathlib.Path("/tmp/path/to/desired/directory").mkdir(parents=True, exist_ok=True)</code>

The exist_ok parameter was new in Python 3.5.

For Python ≥ 3.2, os.makedirs has an optional third argument exist_ok which, when True, enables the mkdir -p functionality except when mode is provided and the directory's The permissions differ from the expected permissions; in this case, an OSError is raised as before:

<code class="python">import os
os.makedirs("/tmp/path/to/desired/directory", exist_ok=True)</code>

For earlier versions of Python, you can use os.makedirs and ignore the error:

<code class="python">import errno
import os

def mkdir_p(path):
    try:
        os.makedirs(path)
    except OSError as exc:  # Python ≥ 2.5
        if exc.errno == errno.EEXIST and os.path.isdir(path):
            pass
        # 还可以在此处理其他errno情况，否则：
        else:
            raise</code>
