swapcase() : Changes uppercase to lowercase and vice versa in Python

swapcase(): Upper case chars to Lower case and and vice versa
All upper case chars are changed to lower case and lower case chars are changed to upper case.

Basic usage:
Inverts the case of each character, making uppercase letters lowercase and vice versa.

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

my_str='Welcome to plus2net Python Section'
output=my_str.swapcase()
print(output)

Output is here

wELCOME TO PLUS2NET pYTHON sECTION

Working with numbers and special characters:
Non-alphabetic characters like numbers and symbols remain unchanged.

text = "Python3.9 is AWESOME!"
result = text.swapcase()
print(result)  # Output: "pYTHON3.9 IS awesome!"

Handling mixed case strings:

text = "WeLcOmE tO PyThOn"
result = text.swapcase()
print(result)  # Output: "wElCoMe To pYtHoN"

Python String swapcase():

Example 2: Using swapcase() with Mixed Cases

text = "Python3.8 is AWESOME"
result = text.swapcase()
print(result)

Output

pYTHON3.8 IS awesome

Example 3: swapcase() in List Comprehensions

Convert each string in a list to swapcased format.

text_list = ["Hello", "World", "Python"]
swapped = [text.swapcase() for text in text_list]
print(swapped)

Output

['hELLO', 'wORLD', 'pYTHON']
