re.compile('..\/img\/gifts/img.*.jpg')

The re.compile pattern benefits from being entered as a raw string.
As written, obtain an error message:
>>>
<>:7: SyntaxWarning: invalid escape sequence '\.'
<>:7: SyntaxWarning: invalid escape sequence '\.'
<<<
Add the lower case r in the following eliminates the error messages:
>>>
re.compile(r'\.\.\/img\/gifts/img.*\.jpg')
<<<

A raw string bonus is not needing to escape the file separator character.

I am using Python 3.12.1.
Thank you for your consideration.
