Python - String swapcase() Method

The swapcase() string method is used to swap the cases of characters in a string, i.e. from lowercase to uppercase or from uppercase to lowercase.

Note : None of the string methods change the original string and only return a new string which reflects the change performed by the string method, hence the returned string must be stored or used(if needed to reflect the result), otherwise it is lost.

Signature of swapcase()

The swapcase() method has no parameters, so we don't have to worry about passing it some value.
