Why does Python's rstrip remove more characters than expected?
Question:
According to the docs the function will strip that sequence of chars from the right side of the string.
The expression 'https://odinultra.ai/api'.rstrip('/api') should result in the string 'https://odinultra.ai'.
Instead here is what we get in Python 3:
>>> 'https://odinultra.ai/api'.rstrip('/api')
'https://odinultra.'
Answers:
rstrip('/api') won’t remove the suffix /api, but a sequence made up of any of the characters /, a, p or i from the end of the string. This isn’t a bug, but the documented behavior:
The chars argument is not a suffix; rather, all combinations of its values are stripped
For your usecase, you should use removesuffix instead:
'https://odinultra.ai/api'.removesuffix('/api')
