SwapCase()
Python SwapCase is one of the Python String Method which is used to convert the Lowercase letters into Uppercase and Uppercase letters into Lowercase and returns new string. In this article we will show you, How to write SwapCase() Function in Python Programming with example.
TIP: The SwapCase() Function will keep the Non-letters unchanged.
Syntax of a Python SwapCase method
The basic syntax of the Python SwapCase function is as shown below:
|
1 |
String_Value.SwapCase() |
String_Value: Please select the valid String variable or you can use the String directly.
Python SwapCase method Example
The following set of examples will help you understand the Python SwapCase() Function,

# Python SwapCase Method Example Str1 = 'Learn PYTHON AT TutOrial GateWay' Str2 = Str1.swapcase() print('First Output of a SwapCase() method is = ', Str2) # Observe the Original String print('Converted String is = ', Str1.swapcase()) print('Original String is = ', Str1) # Performing Swapcase() function directly Str3 = 'PYTHON ProGrammING'.swapcase() print('Second Output of a SwapCase() method is = ', Str3) Str4 = 'python1234TUTORIAL'.swapcase() print('Third Output of a SwapCase() method is = ', Str4) Str5 = '12345'.swapcase() print('Fourth Output of a SwapCase() method is = ', Str5) |
OUTPUT
ANALYSIS
First we declared the String variable Str1 and assigned corresponding value using following statement
|
1 |
Str1 = 'Learn PYTHON AT TutOrial GateWay' |
Following statement will convert the above string as: lowercase letters into uppercase and uppercase letters into lowercase using SwapCase() function and prints the output
|
1 2 |
Str2 = Str1.swapcase() print('First Output of a SwapCase() method is = ', Str2) |
The SwapCase() function in Python will return the output in new string, instead of alter the original string. Following statements will show you the same
|
1 2 |
print('Converted String is = ', Str1.swapcase()) print('Original String is = ', Str1) |
From the above screenshot you can observe that the, original string Str1 is unchanged. If you want to chnage the original String then, you can write the following statement
|
1 |
Str1 = Str1.swapcase() |
The Python SwapCase function will only convert the lowercase letters to uppercase and uppercase letters to lowercase but it will leave other values unchanged. Within the following statements we used the numeric values along with letters and you can see the output for further reference
|
1 2 3 4 5 |
Str4 = 'python1234TUTORIAL'.swapcase() print('Third Output of a SwapCase() method is = ', Str4) Str5 = '12345'.swapcase() print('Fourth Output of a SwapCase() method is = ', Str5) |
