Python String casefold() method is used to convert string to lowercase. It is similar to the Python lower() string method, but the case removes all the case distinctions present in a string.
Python String casefold() Method Syntax
Syntax: string.casefold()
Parameters: The casefold() method doesn’t take any parameters.
Return value: Returns the case folded string the string converted to lower case.
Python String casefold() Method Example
Python3
string = "GEEKSFORGEEKS"print("lowercase string: ", string.casefold()) |
Output:
lowercase string: neveropen
Difference between casefold() and lower() in Python
Python String casefold() Method is more aggressive in conversion to lowercase characters because it tends to remove all case distinctions in a String.
Python3
string = "ß"print("Using lower():", string.lower())print("Using casefold():", string.casefold()) |
Output:
Using lower(): ß Using casefold(): ss
Practical Example using Python String casefold() Method
Here, we have a Python String with characters of mixed cases. We are using the Python casefold() Method to convert everything to lowercase.
Python3
string = "WeightAGE oF THe DiScuSSiON"print("Original String:", string)# print the string after casefold transformationprint("String after using casefold():", string.casefold()) |
Output:
Original String: WeightAGE oF THe DiScuSSiON String after using casefold(): weightage of the discussion
