Programming languages, such as Python, treat a backslash (\) as an escape character. For instance, \n represents a line feed, and \t represents a tab. When specifying a path, a forward slash (/) can be used in place of a backslash.
os. path. join combines path names into one complete path. This means that you can merge multiple parts of a path into one, instead of hard-coding every path name manually.
path. join() method in Python join one or more path components intelligently. This method concatenates various path components with exactly one directory separator ('/') following each non-empty part except the last path component.
os. sep. The character used by the operating system to separate pathname components. This is '/' for POSIX and '\\\\' for Windows.
os.path.join(path, '') will add the trailing slash if it's not already there.
You can do os.path.join(path, '', '') or os.path.join(path_with_a_trailing_slash, '') and you will still only get one trailing slash.
Since you want to connect a directory and a filename, use
os.path.join(directory, filename)
If you want to get rid of .\..\..\blah\ paths, use
os.path.join(os.path.normpath(directory), filename)
You can do it manually by:
path = ...
import os
if not path.endswith(os.path.sep):
path += os.path.sep
However, it is usually much cleaner to use os.path.join.
