Python String swapcase() Method

For this method, no external module needs to import. Wherever you want to modify a string’s character cases, call it. Let’s have a look at the swapcase() definition:

The Python String swapcase() function transforms the case of uppercase string characters to lowercase and vice versa. There is no parameter needed, and a string returns after case conversion.

The syntax of the method is: str.swapcase();

Key Points :

• Return Type: String.
• Parametric values: No parameters are taken into the swapcase() function.
• The swapcase() returns the string of which all uppercase characters are translated into the lowercase, and lowercase characters are translated into uppercase.
• Suppose a string is a=”ABC” is given, and if the swapcase() method is applied to it, it will be abc.

Below is the python program to demonstrate the swapcase() function:

str = "The Best Learning Resource for Online Education";
print (str.swapcase())
str = "THE BEST LEARNING RESOURCE FOR ONLINE EDUCATION";
print (str.swapcase())

When we run above the program, the outcome is as follows:

tHE bEST lEARNING rESOURCE FOR oNLINE eDUCATION

the best learning resource for online education
