lower( ) FUNCTION

The lower() Function is used to convert all the characters/letters of the String in lower case.

x = "HeLLo"
y = x.lower()
print("The String in lower case is ",y)

Output :

The String in lower case is hello

In the above code, we have declared a String 'HeLLo', in which the letters 'H' and two 'L's are in upper case.

x = "HeLLo"

So, we have used the 'lower( )' Function to convert them to lower case and assign to a variable 'y'.

y = x.lower( )
