lower() string method in python

Below are the different types of examples of theΒ python lower() method.

Example 1:


Output :

hello coders

Example 2:

str="hello coders"

Output :

hello coders

Hence, if the string is already in lowercase then it will change nothing.

Example 3:

str="Hello Coders"
print (str.lower()) 

Output :

hello coders

Example 4:

str="HeLLo CoDers"
print (ans)

Output :

hello coders

Example 5:

str="Be you"
str. lower() 
print (str) 

Output :

Be you

As you can see, the above output is still the same because we can not change the existing string. But if we print the, str. lower () then it will print the ‘be you’.
