The lower() method in Python

In this example, we have stored a string in variable ‘string1’ which includes uppercase letters, and converted it to lowercase using the lower() method after that we printed that converted string.

Python3




# Define a string
string1 = "w3wiki"
print(string1)
  
# Store the output of lower() method
# in string2 
string2 = string1.lower()
print(string2)


Output:

w3wiki
