Chained str.replace calls can sometimes be pretty unattractive; what are the chances that we could have an str.replaceall method? Of type Callable[[Mapping[str, str]], str]?

Check out absl::StrReplaceAll ( for a similarly useful function in C++.

Hi, the bug tracker is not the right place to propose to add a new method to the builtin str type. I suggest to propose it on the python-ideas list. I'm quite sure that it was proposed at least once, so please search in the archives.

Versions 3.6-3.9 are all in feature-freeze, so the earliest this could be added is version 3.10.
