os.truncate()

os.truncate() is a Python function in the OS Module category. Truncates the file to the given length (in bytes). The syntax is os.truncate(path, length). Parameters: path, length. Returns: None. A typical example: os.truncate("file.txt", 0) # Empty the file. A close sibling is os.getcwd(), which returns the current working directory as a string. A close sibling is os.chdir(), which changes the current working directory to the given path. A close sibling is os.listdir(), which returns a list of all files and directories in the given path. A close sibling is os.mkdir(), which creates a single directory. Raises FileExistsError if it already exists.
