The bulk replacement directory of the Python script Toolbox in Ko Tao the specified string in all files with the specified extension

Today released the newly completed Python script toolbox of the bulk replacement directory for all specified extensions in the file with the specified string, command-line parameter processing instead of using the Argparse library, the Python code is as follows:
