Python programming code to check whether the character is Alphabet or not

In this post, we will discuss the concept of Python programming code to check whether the character is Alphabet or not

Here, we are going to learn how to find whether the given character is Alphabet or not in Python programming language

Python programming code to check whether the character is Alphabet or not — Alphabet or not

What is ASCII

In the Python programming language, all the character variables hold an ASCII value for computer usage.ASCII value is represented by integer values between 0 to 127.
The ASCII value of lowercase Alphabets are from 97 to 122 and The ASCII value of uppercase Alphabets are from 65 to 90

Python programming code to check whether the character is Alphabet or not

This concept is done using two ways

using if-else statements
Using ASCII value

Python code to check the character is Alphabet or not using if-else

The program allows the user to enter a character thereafter it will check and display the result of the given character whether it is an alphabet or non-alphabet using the if-else statements in Python language

Program 1

#Python programming code to check whether the character is Alphabet or not
ch=input("Please enter the character as you wish: ")

if((ch>='A' and ch<='Z')or(ch>='a' and ch<='z')):
   print(ch," is an Alphabet: ");

else:

   print(ch," is not an Alphabet: ");

When the above code is executed it produces the following result

Case 1

Enter a character as you wish: Y
Y is an Alphabet

Case 2

Enter a character as you wish: c
c is an Alphabet

Case 3

Enter a character as you wish: &
& is not an Alphabet

Approach

In the program, the user is asked to enter a character and entered character is stored in character variable ch
The program evaluates whether the entered character is an Alphabet or not, using if statements
If the given character is an Alphabet The program displays the output “it is an Alphabet” and if the given character is not an Alphabet it will display”it is not an Alphabet”

Python code to check the character is Alphabet or not using ASCII value

The program allows the user to enter a character thereafter it will check and display the result of the given character whether it is an alphabet or non-alphabet using ASCII value

Program 2

#Python programming code to check whether the character is Alphabet or not
ch=input("Please enter the character as you wish")

if((ord(ch)>=65 and ord(ch)<=90)or(ord(ch)>=97 and ord(ch)<=122)):
   print(ch," is an Alphabet: ");

else:

   print(ch," is not an Alphabet: ");

When the above code is executed it produces the following result

Case 1

Enter a character as you wish: D
D is an Alphabet

Case 2

Enter a character as you wish: z
z is an Alphabet

Case 3

Enter a character as you wish: 7
7 is not an Alphabet

Approach

In the program, the user is asked to enter a character and entered character is stored in character variable ch
The program evaluates whether the entered character is an Alphabet or not, using ASCII value
If the given character is an Alphabet The program displays the output “it is an Alphabet” and if the given character is not an Alphabet it will display”it is not an Alphabet”

The Alphabet has ASCII values between 65 to 90(capital letters) and 97 to 122 (small letters)
