Python Program to check character is Lowercase or Uppercase

by

In this article we will show you, How to write a Python program to check character is Lowercase or Uppercase with practical example.

Python Program to check character is Lowercase or Uppercase using islower, and isupper functions

In this program, we are using a built-in string functions called islower, and isupper to check whether a given character is lowercase or uppercase.

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

if(ch.isupper()):
    print("The Given Character ", ch, "is an Uppercase Alphabet")
elif(ch.islower()):
    print("The Given Character ", ch, "is a Lowercase Alphabet")
else:
    print("The Given Character ", ch, "is Not a Lower or Uppercase Alphabet")

Python Program to check character is Lowercase or not

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

  • Here, If statement check whether the character is greater than or equal to small a, and less than or equal to z. If it is TRUE, it is an uppercase otherwise, it will enter into elif statement.
  • Inside the Elif, we are checking whether the given character is greater than or equal to A, and less than or equal to Z. If it is True, its is a lowercase character otherwise, it is not a lower or uppercase Alphabet.
# Python Program to check character is Lowercase or Uppercase
ch = input("Please Enter Your Own Character : ")

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

Python Program to check character is Lowercase or not using ASCII Values

In this program, we are using ASCII Values to check the character is uppercase or lowercase.

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

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