Write a Python program to check character is Alphabet or Digit with a practical example.

Python Program to check character is Alphabet or Digit

This python program allows a user to enter any character. Next, we are using Elif Statement to check whether the user given character is alphabet or digit.

  • Here, If statement checks whether the character is between a and z or between A and Z, if it is TRUE, it is an alphabet. Otherwise, it enters into elif statement.
  • Inside the Elif Statement, we are checking whether a given character is between 0 and 9. If it is true, it is a digit; otherwise, it is not a digit or alphabet.
# Python Program to check character is Alphabet or Digit
ch = input("Please Enter Your Own Character : ")

if((ch >= 'a' and ch <= 'z') or (ch >= 'A' and ch <= 'Z')): 
    print("The Given Character ", ch, "is an Alphabet") 
elif(ch >= '0' and ch <= '9'):
    print("The Given Character ", ch, "is a Digit")
else:
    print("The Given Character ", ch, "is Not an Alphabet or a Digit")

Python Program to verify character is Alphabet or Digit using ASCII Values

In this Python code, we are using ASCII Values to check the character is an alphabet or digit.

# Python Program to check character is Alphabet or Digit
ch = input("Please Enter Your Own Character : ")

if(ord(ch) >= 48 and ord(ch) <= 57): 
    print("The Given Character ", ch, "is a Digit") 
elif((ord(ch) >= 65 and ord(ch) <= 90) or (ord(ch) >= 97 and ord(ch) <= 122)):
    print("The Given Character ", ch, "is an Alphabet")
else:
    print("The Given Character ", ch, "is Not an Alphabet or a Digit")

Python Program to find character is Alphabet or Digit using isalpha, isdigit functions

In this example python code, we use string functions called isdigit and isalpha to check whether a given character is an alphabet or digit.

# Python Program to check character is Alphabet or Digit
ch = input("Please Enter Your Own Character : ")

if(ch.isdigit()):
    print("The Given Character ", ch, "is a Digit")
elif(ch.isalpha()):
    print("The Given Character ", ch, "is an Alphabet")
else:
    print("The Given Character ", ch, "is Not an Alphabet or a Digit")
