Python String swapcase()
In Python, String swapcase()
is an inbuilt method which is used for string handling.
-
As from the name it is clear that here is swapping of the case which in turn means that this method is used to swap the case of a string.
-
This method converts the string which is in Uppercase into Lowercase case and vice -versa.
-
Suppose a string is a="ABC"
is given and if swapcase()
method is applied on to it then result will be abc.
Python String swapcase()
: Syntax
Below we have a basic syntax of String swapcase()
in Python:
string.swapcase()
Note: In the above syntax; string denotes the string value that holds the input value whose case is needed to be changed or to which we will apply swapcase()
method.
Python String swapcase()
: Parameters
From the syntax of this method, it is clearly seen that there is no parameter in this method.
- If we pass any parameter to this method then this method will raise an error.
Python String swapcase()
: Returned Values
For the returned value there are two cases:
Python String swapcase()
: Basic Example
Below we have an example to show the working of String swapcase()
function:
h1= “Hello StudyTonight”
h1.swapcase()
The Output for the same is given below; always remember this method does not take any parameters:
hELLO sTUDYtONIGHT
String swapcase()
: Another Example
a = "joHn Cena"
b = "Hello StudyTonight"
c = "Qwerty"
print("Original String: ", a, "Case changed: ", a.swapcase())
print("Original String: ", b, "Case changed: ", b.swapcase())
print("Original String: ", c, "Case changed: ", c.swapcase())
In the above example, we print the values of the original string as well result after swapcase()
is applied to them. The Output for the same is given below:
Original String: joHn Cena Case changed: JOhN cENA
Original String: Hello StudyTonight Case changed: hELLO sTUDY tONIGHT
Original String: Qwerty Case changed: qWERTY
Time For Live Example!
Now its time to see a Live example of swapcase()
method which is given below:
Summary
In this tutorial, we have learned the swapcase()
method of strings in Python with the help of which we can convert an uppercase character into lowercase and vice-versa. We also discussed its parameters and returned values followed by a Live example.
