How To Use Python String Swapcase Method – Easy Python Example Code

In this tutorial, we’ll learn what Python string swapcase() method is and how to properly use it. We’ll go through multiple Python code examples to understand how swapcase() method works in Python.

Introduction: Python String swapcase() Method

This method converts the case format of all alphabets in a string. If an alphabet is in lowercase format then it’ll be converted to uppercase and vice versa.

Syntax of swapcase() Method

string.swapcase()

• Python string swapcase() method does not take any arguments.
• This method returns a string having all its alphabets converted to their opposite case format.

Example 1: swapcase() applied on a Python String

strValue='This IS PythON.'
print(strValue.swapcase())
print('PYTHON'.swapcase())
print('python'.swapcase())
print('PYThon'.swapcase())
print('pytHoN'.swapcase())

Output

tHIS is pYTHon. 
python 
PYTHON 
pytHON 
PYThOn

We can see that all the alphabets in the above strings are converted to their opposite case format(converted to lowercase if alphabet is initially in uppercase and vice versa).

See below example as well in which Python string swapcase method is applied on a string having non-English alphabet.

print('groß'.swapcase())       // ß its a german word(ß is ss in English)

Output

GROSS       // ß is ss in English so its converted to capital SS

Example 2: swapcase() Method Return Value

val='This Is Python.'
returnedVal=val.swapcase()
print(returnedVal)

Output

tHIS iS pYTHON.
