How can I create directories in Python, including intermediate directories, if they don\'t already exist?

mkdir -p functionality in Python (duplicate)

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

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

Python≥3.5 introduced the exist_ok parameter.

For Python ≥ 3.2, os.makedirs has an optional third parameter exist_ok. When exist_ok is True, the mkdir -p function is available, unless mode is provided and the permissions of the existing directory are different than expected. ; In this case, OSError will be 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>
