Resolving the "~" Not Recognized Issue in "os.makedirs" Paths
When working with paths that contain the "~" character, signifying the user's home directory, Python's "os.makedirs" function may encounter difficulties. The reason is that "~" is not automatically expanded by the function.
To resolve this issue and accurately create directories in the intended home directory, you must manually expand the "~" character. This can be achieved using the "os.path.expanduser" function. Here's how:
my_dir = os.path.expanduser('~/some_dir')
By expanding the "~" character, you explicitly specify that the "some_dir" directory should be created within your home directory, effectively rectifying the issue encountered with "os.makedirs" not recognizing "~".
The above is the detailed content of How to Create Directories with '~' in Path Using 'os.makedirs'?. For more information, please follow other related articles on the PHP Chinese website!

The basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.
