    In this interesting thread, the users give some options to create a directory if it doesn't exist.

    The answer with most votes it's obviously the most popular, I guess because its the shortest way:

    if not os.path.exists(directory):
    os.makedirs(directory)


    The function included in the 2nd answer seems more robust, and in my opinion the best way to do it.

    import os
    import errno

    def make_sure_path_exists(path):
    try:
    os.makedirs(path)
    except OSError as exception:
    if exception.errno != errno.EEXIST:
    raise


    So I was wondering, what does people do in their scripts? Type 2 lines just to create a folder? Or even worst, copy, and paste the function make_sure_path_exists in every script that needs to create a folder?

    I'd expect that such a wide spread programming language as Python would already have a library with includes a similar function.

    The other 2 programming languages that I know, which are more like scripting languages, can do this with ease.

    Bash: mkdir -p path

    Powershell: New-Item -Force path

    Please don't take this question as a rant against Python, because it's not intended to be like that.

    I'm planing to learn Python to write scripts where 90% of the time I'll have to create folders, and I'd like to know what is the most productive way to do so.

    I really think I'm missing something about Python.
