Python program to check whether a character is alphabet or not

In this article, you will learn how to check whether a character is an alphabet or not using if-else and Ternary operator in the python programming language.

Examples

You should have knowledge of the following topics in python programming to understand these programs:

• Python Ternary operator
• Python input() function
• Python str() function
• Python if-else condition statement
• Python print() function

1. Python program to check whether a character is an alphabet or not using if-else statement

# Python program to check whether a character is alphabet or not

print ("Enter a character to check itself: ", end="")
char = str (input ())[0]

if (char >= 'a' and char <= 'z') or (char >= 'A' and char <= 'Z'):
    print (char, "is an alphabet character.")
else:
    print (char, "is not an alphabet character.")

2. Python program to check whether a character is an alphabet or not using Ternary operator

# Python program to check whether a character is alphabet or not using conditional operator

print ("Enter a character to check itself: ", end="")
char, flag = str (input ())[0], False

flag = True if (char >= 'a' and char <= 'z') or (char >= 'A' and char <= 'Z') else False

if flag:
    print (char, "is an alphabet character.")
else:
    print (char, "is not an alphabet character.")

Run Program

Output

Explanation

In this program, we have taken input A from the user then it passes to check this character between alphabetic series.

a, b, ..., y, z

A, B, ..., Y, Z

Although the given character does exist in this series or not if it doesn't in this series then the given character is not alphabetic.
