Python | Print Alphabets till N

In this tutorial, we'll learn how to print alphabets (letters) up to a given count N. For instance, if N is 5, we should print the first 5 letters: A B C D E.

Objective:

Print the first N alphabets.

Steps and Python Code:

1. Using ASCII values:

Every character has a corresponding ASCII value. Uppercase 'A' has the value 65, and 'Z' has 90. We can leverage this to print alphabets.

def print_alphabets(N): # Ensure the given N is within the valid range if 1 <= N <= 26: for i in range(N): print(chr(65 + i), end=" ") else: print("Please provide a value between 1 and 26.") # Example usage: N = 5 print_alphabets(N) # Output: A B C D E

2. Using string module:

The Python string module provides sequences of common ASCII characters, including a sequence of all uppercase letters.

import string def print_alphabets(N): # Ensure the given N is within the valid range if 1 <= N <= 26: print(" ".join(list(string.ascii_uppercase)[:N])) else: print("Please provide a value between 1 and 26.") # Example usage: N = 5 print_alphabets(N) # Output: A B C D E

Explanation:

  • In the first method, we start with ASCII value 65 ('A') and keep incrementing it in a loop to print the letters. The chr() function is used to convert an ASCII value to its corresponding character.

  • In the second method, string.ascii_uppercase gives a string of all uppercase letters. By converting it to a list and slicing, we can get the first N letters easily.

Considerations:

  • We assume the alphabet sequence requested is the English uppercase letters (from 'A' to 'Z'). The count N must be between 1 and 26 to be valid.

By following this tutorial, you've learned how to print the first N alphabets using Python.
