Python Script to Replace Text in Multiple Files

Here is an example of a Python script that replaces a specific text in multiple files:

import os
import glob

# specify the directory containing the files
directory = '/path/to/directory'

# specify the file extension
file_extension = '*.txt'

# specify the text to be replaced and the replacement text
old_text = 'old_text'
new_text = 'new_text'

# get a list of all the files in the directory with the specified extension
files = glob.glob(os.path.join(directory, file_extension))

# loop through the files
for file_path in files:
    # open the file and read its contents
    with open(file_path, 'r') as file:
        file_contents = file.read()
    
    # replace the text
    new_contents = file_contents.replace(old_text, new_text)
    
    # open the file again in write mode
    with open(file_path, 'w') as file:
        file.write(new_contents)

This script uses the glob library to find all the files with the specified extension in the specified directory, then loops through each file and replaces the old text with the new text. You can change the directory, file extension, old text, and new text to suit your needs. Also, as an alternative, you can use os.scandir() to loop through all the files in the directory, and then use the same logic to replace the text in each file.
