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>

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
