Several example codes

Program Overview

This Python program reads a single character from the user and determines its type.
It checks whether the character is a digit, an uppercase letter, or a lowercase letter.
The result is displayed using a variable that stores the character type.

Python Code:

def detect_character_type(ch: str) -> str:
    if ch.isdigit():
        return "Digit"
    elif ch.isupper():
        return "Uppercase Letter"
    elif ch.islower():
        return "Lowercase Letter"
    else:
        return "Other"

# Read character from user
char = input("Enter a single character: ").strip()

if len(char) != 1:
    print("Please enter exactly one character.")
else:
    result = detect_character_type(char)
    print(f"The character '{char}' is a: {result}")

Sample Output (input: A):

The character 'A' is a: Uppercase Letter

Step-by-Step Explanation:

- The user enters a single character
- The program checks its type using built-in string methods:
.isdigit(), .isupper(), and .islower()
- The result is stored in a variable and displayed
- If the input is not a single character, an error message is shown
