Py string methods

Python provides string methods that allows us to chop a string up according to delimiters that we can specify. In other words, we can tell Python to look for a certain substring within our target string, and split the target string up around that sub-string. It does that by returning a list of the resulting sub-strings (minus the delimiters).

Definition and Usage. The rindex () method finds the last occurrence of the specified value. The rindex () method raises an exception if the value is not found. The rindex () method is almost the same as the rfind () method. See example below. Using casefold() Method ; String with Case-Insensitive Comparison; 1. Convert a String to Uppercase Using upper() Method . Here we are using the string upper() in Python.
