Python String swapcase() Method

The Python swapcase() method is used to convert all uppercase characters to lowercase and vice versa of a given string. It returns a new string with the cases swapped.

For example:

text = "Hello World"
result = text.swapcase()
print(result)
# Output: hELLO wORLD

You can also use swapcase() on a string that contains a mix of upper and lower case characters. All cases will be reversed when swapcase() method is called.

For example:

text = "HeLLo WoRld"
result = text.swapcase()
print(result)
# Output: hEllO wOrLD
