can you provide a python code to rename all files in a directory with a pattern
Certainly! Here’s an example of Python code that renames all files in a directory with a specified pattern:
import os
def rename_files(directory_path, pattern):
for filename in os.listdir(directory_path):
if os.path.isfile(os.path.join(directory_path, filename)):
new_filename = pattern.replace(‘*’, filename)
os.rename(os.path.join(directory_path, filename), os.path.join(directory_path, new_filename))
print(f”Renamed {filename} to {new_filename}”)
# Example usage
directory_path = ‘/path/to/directory’
pattern = ‘new_*’
rename_files(directory_path, pattern)
In this code, the `rename_files` function takes two parameters: `directory_path` (the path to the directory containing the files) and `pattern` (the pattern you want to use for renaming the files).
The function iterates over each file in the directory using `os.listdir`. For each file, it checks if it’s a regular file using `os.path.isfile`. If it is, the function generates the new filename by replacing the `*` wildcard in the pattern with the original filename. Then, it uses `os.rename` to rename the file with the new filename.
Note that you should replace `’/path/to/directory’` with the actual path to your directory, and `’new_*’` with the desired pattern. Make sure you have the necessary permissions to rename files in the specified directory.
Also, please exercise caution when running this code, as it performs actual file renaming operations. It’s always a good idea to make a backup of your files before running any bulk renaming operations.
