How can i change file name while copying them using shutil?

I am using shutil to copy my files to another destination directory , what i want to achieve is

src/red.png
src/blue.png
src/green.png

for example if i select blue and green then while saving i want them to be saved as

dst/blue_1001.png
dst/green_1002.png

Thanks

Solution

  • All you need to do is to construct a destination path in a format that you want and shutil will do rest of the job.

    I am using pathlib module here because it provides convenient APIs to work with paths.

    >>> import shutil
>>> from pathlib import Path
>>> 
>>> files_to_copy = ["src/red.png", "src/blue.png"]
>>> 
>>> destination = Path("dst")
>>> 
>>> for index, file in enumerate(map(Path, files_to_copy), start=1001):
...     destination_filename = f"{file.stem}_{index}{file.suffix}"
...     print(f"{destination_filename=}")
...     _ = shutil.copy(file, destination / destination_filename)
... 
destination_filename='red_1001.png'
destination_filename='blue_1002.png'
