Python string Method - swapcase()

The swapcase() method is a built-in string method in Python that returns a copy of a string with uppercase characters converted to lowercase and lowercase characters converted to uppercase.

The syntax for using swapcase() method is as follows:

string.swapcase()

Here, string is the original string.

The method returns a new string with uppercase characters converted to lowercase and lowercase characters converted to uppercase.

Here's an example of using the swapcase() method:

string = "Hello, World!"
swapped_string = string.swapcase()
print(swapped_string)

Output:

hELLO, wORLD!

In the example above, the swapcase() method was used to convert the original string "Hello, World!" to a new string with uppercase and lowercase characters swapped. The resulting string is stored in the variable swapped_string. Note that uppercase characters are converted to lowercase and lowercase characters are converted to uppercase.
