How do I uppercase or lowercase a string in Python?
To uppercase a string in Python, you can use the upper()
method of the string. For example:
string = "hello"
uppercase_string = string.upper()
print(uppercase_string) # prints "HELLO"
To lowercase a string in Python, you can use the lower()
method of the string. For example:
string = "HELLO"
lowercase_string = string.lower()
print(lowercase_string) # prints "hello"
Both upper()
and lower()
are string methods, so they can be called on any string object in Python. They do not modify the original string, but instead return a new string with the uppercase or lowercase version of the original string.
