Python Program to Print Alphabets from A to Z in Uppercase and Lowercase

Python program to print all alphabets from a to z in uppercase and lowercase; In this python article, we would love to share with you how to print alphabets from a to z in uppercase and lowercase in the python using loop.

Before we create programs in python to display alphabets in python, we must know about ASCII.

What is ASCII?

ASCII stands for the American Standards Code for Information exchange. It provides us the numerical value for the representation of characters. The ASCII value of uppercase letters and lowercase alphabets start from 65 to 90 and 97-122 respectively.

1: Write a python program to print all alphabets from a to z using for loop

# write a python program to print alphabets in uppercase from a to z

print("Uppercase Alphabets are:")
for i in range(65,91):
        ''' to print alphabets with seperation of space.'''
        print(chr(i),end=' ') 

Output

Uppercase Alphabets are:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 

2: Python program to print a to z in alphabets in lowercase using for loop

# write a python program to print alphabets in lowercase from a to z

print("\nLowercase Alphabets are:")
for j in range(97,123):
        print(chr(j),end=' ')

Output

Lowercase Alphabets are:
a b c d e f g h i j k l m n o p q r s t u v w x y z

In the above python program, you have learned how to print alphabets from a to z in uppercase and lowercase.

Now you will learn another python program, which is used to check entered value is an alphabet or not.

3: Python Program to Check Alphabet

• Take input from user.
• Store an input value in the variable.
• Check enter value is alphabet or not
• Print result.

# Python Program to Check Alphabet
ch = input("Enter a character: ")
if((ch>='a' and ch<= 'z') or (ch>='A' and ch<='Z')):
    print(ch, "is an Alphabet")
else:
    print(ch, "is not an Alphabet")

Output

Enter a character:  4
4 is not an Alphabet
