Now imagine it's five years from now, and you're using Python 3.11, and
you came across code somebody (possibly even you!) wrote:
ifname = ifname.cutsuffix(':')
Would you say "Damn, I wish that method had never been added!" and
replace it with the earlier code above?
Just a late followup to this thread.
The other month I found myself doing the endwith/s=s[:-n] shuffle yet
again, and wrote a pair of cutprefix and cutsuffix functions. They're
available in my "cs.lex" PyPI module if anyone wants to use them. Their
signature is:
prefix = cutsuffix(original_string, suffix)
if prefix is original_string:
# suffix not present ...
else:
# suffix present, proceed using prefix
and the converse for cutprefix.
