Python string to Uppercase – str.upper() with Examples [Latest]

Python String to Uppercase

Let’s look at a simple example of converting a string to uppercase and print it.

s="abcDEF%$"
print('Uppercase String =', s.upper())
print('Original String =', s)

Output:

Uppercase String = ABCDEF%$
Original String = abcDEF%$

Notice that when we call upper() on a string object, the original string remains unchanged. This function creates another string with uppercase characters and returns it.

Python String upper() with user input

Let’s have a look at another example where we will get the user input and convert it to uppercase and print it.

s = input('Please Provide Input Stringn')
print('Input String in Uppercase=", s.upper())
print("Original String =', s)

Output:

Please Provide Input String
JournalDev is Awesome!!
Input String in Uppercase = JOURNALDEV IS AWESOME!!
Original String = JournalDev is Awesome!!
