Thank you, this is a simple, unambiguous proposal which meets a real need and will help prevent a lot of wasted developer time misusing [lr]strip and then reporting it as a bug: remove a single prefix or suffix.
This is a useful string primitive provided by other modern languages and libraries, including Go, Ruby, Kotlin, and the Apache StringUtils Java library: https://golang.org/pkg/strings/#TrimPrefix https://golang.org/pkg/strings/#TrimSuffix https://ruby-doc.org/core-2.5.1/String.html#method-i-delete_prefix https://ruby-doc.org/core-2.5.1/String.html#method-i-delete_suffix https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/remove-prefix.html https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/remove-suffix.html https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#removeStart-java.la$ https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#removeEnd-java.lang$ Regarding later proposals to add support for multiple affixes, to recursively delete the affix repeatedly, and to take an additional argument to limit how many affixes will be removed: YAGNI. Let's not over-engineer this to be something which is ambigious and complex. We can add more complexity later, if and when practical experience suggests: (1) that multiple affixes actually is useful in practice, not just a "Wouldn't It Be Cool???" feature; and (2) a consensus as to how to handle ambiguous cases. Until then, let's keep it simple: methods to remove a *single* prefix or suffix, precisely as given. Anything else is YAGNI and is best left for the individual programmer. -- Steven _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
