…ealpath() On Windows abspath() resolves a drive-relative path against the current directory of the specified drive, capitalizes the drive letter and strips trailing dots and spaces, so the result can differ from normpath(join(os.getcwd(), path)). realpath() returns the path in the case reported by the operating system.

On Windows
abspath()is not equivalent tonormpath(join(os.getcwd(), path)), as the documentation says: the path is normalized by the operating system, so a drive-relative path is resolved against the current directory of the specified drive, the drive letter is capitalized, and trailing dots and spaces are stripped.realpath()returns the path in the case reported by the operating system, in particular with the capitalized drive letter. It was reported as a bug, but it is the intended behavior, because since 3.8 it queries the final path from the system.
