• In python it is a string’s function which converts all uppercase characters into lowercase and vice versa.
• This function is used to alter the existing case of the string.
• In swapcase this method creates a copy of the string which contains all the characters.
• It generates a small case string and vice versa, if the string is in lowercase and automatically ignores all the non-alphabetic characters.
• The swapcase function does not takes any parameter.
• With all the cases changed the swapcase () method returns a string.

Sample Code

# Python program to demonstrate the use of
# swapcase() method  
  
string = "Welcome to Wikitechy"
  
# prints after swappong all cases
print(string.swapcase())   
  
string = "striver" 
print(string.swapcase())
