Lowercase String : python examples2. Convert String (with all uppercase characters) to Lowercase
In this example, we take a string with all uppercase alphabets. And convert the string to lowercase.

lowerstring = mystring.lower()
print('Lowercase String :',lowerstring)Output
Original String : HTTPS://PYTHONEXAMPLES.ORG
Lowercase String : https://pythonexamples.orgSummary
In this tutorial of Python Examples, we learned to transform a given string to lowercase using string.lower() method, with the help of well detailed examples.
