Strings are interned at compile time ('wtf' will be interned but ''.join(['w', 't', 'f']) will not be interned) Strings that are not composed of ASCII letters, digits or underscores, are not interned. This explains why 'wtf!' was not interned due to !. CPython implementation of...
In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
