In this tutorial, I’ll show you how to retrieve ASCII codes from characters and vice versa using Python’s `ord` and `chr` functions. These skills will enhance your understanding of character encoding and data manipulation.

'''
In Python, you can use the ord() function to get the ASCII code of a character and the chr() function to get the character represented by an ASCII code. Here's how you can use these functions:
'''
'''
Getting the ASCII Code of a Character
To get the ASCII code of a character, use the ord() function:
'''
def get_ascii_code_of_a_character():
char = 'A'
ascii_code = ord(char)
print(ascii_code) # Output: 65
'''
Getting the Character from an ASCII Code
To get the character represented by an ASCII code, use the chr() function:
'''
def get_character_from_an_ascii_code():
ascii_code = 85
char = chr(ascii_code)
print(char)
def get_string_character_ascii_code():
string = "Hello"
# use list comprehension to get all the character's ascii code in a string.
ascii_codes = [ord(char) for char in string]
print(ascii_codes) # Output: [72, 101, 108, 108, 111]
'''
go to url https://www.ascii-code.com/ to get all ascii code.
The first 32 characters in the ASCII-table are unprintable control codes and are used to control peripherals such as printers.
'''
def get_all_ascii_code_and_mapped_characters():
# Iterate through ASCII codes from 0 to 127 and print each code and its corresponding character
for code in range(128):
character = chr(code)
print(f"ASCII Code: {code} Character: {character}")
