Python string upper() method explanation with example:
Python string upper() method is used to convert each character of the string to upper case. This method is defined as below :
string.upper()This method doesn’t take any parameter and it returns the new string with all characters as uppercase.
Example of python upper:
Let me show you an example of python upper:
given_string = "Hello World !!"
print(given_string.upper())This program will print:
HELLO WORLD !!Use python upper by taking user input:
Let’s change the above program to take one string as input from the user and convert it to uppercase:
given_string = input("Enter a string : ")
print("Lowercase : {}".format(given_string.upper()))It will give output as like below:
Enter a string : Hello World !!
Lowercase : HELLO WORLD !!Example to compare two strings by converting strings to upper:
We can use upper() to convert a string to upper case and convert it with a different string by converting that string to upper. For example:
first_string = input("Enter a string : ")
second_string = input("Enter the second string : ")
if(first_string.upper() == second_string.upper()):
print("Both strings are equal")
else:
print("Strings are not equal")In this program, we are comparing two strings without considering the cases.
It will print outputs like below:
Enter a string : hello world
Enter the second string : Hello World
Both strings are equal
Enter a string : hello
Enter the second string : world
Strings are not equal
