[New-bugs-announce] [issue36410] Proposal to make strip/lstrip/rstrip more explicit

[Alex Grigoryev]

New submission from Alex Grigoryev <evrial at gmail.com>:

These methods have confusing implicit behavior. I propose to make it explicit, either strip the exact sequence or chars or leave the string as is.

In [1]: 'mailto:maria at gmail.com'.lstrip('mailto')
Out[1]: ':maria at gmail.com'

In [2]: 'mailto:maria at gmail.com'.lstrip('mailto:')
Out[2]: 'ria at gmail.com'

In [3]: 'mailto:maria at gmail.com'.lstrip('ailto:')
Out[3]: 'mailto:maria at gmail.com'
