How to convert ASCII text to decimal bytes?

Question

I hope you can help.

I am currently looking into the conversion between ASCII character and Decimal (bytes) on a raspberry pi 4b. I am after a code that does the following.

Looks for the users input (text) such as "Hello world" Converts the text given into decimal bytes, and prints the conversion, such as "72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100" Then converts the decimal bytes into ASCII, and printing the text "Hello world" This may seem odd, but being able to see how to make both conversions will allow me to manipulate and change the code for my bigger project.

I need the code to be suitable for a raspberry pi working with python3

Thank you in advance.

I have tried numerous times to get this to work, but seem to be going round in circles. Any help would be appreciated.

Here's one solution:

# Example string
text = "Hello World"

# Convert each character to its ASCII decimal value
ascii_values = [ord(char) for char in text]

print("Converted into Decimals: ",ascii_values)

# Convert each ASCII value back to its character
text = ''.join([chr(value) for value in ascii_values])

print("Converted nack to ASCII: ",text)

Output:

Converted into Decimals:  [72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100]
Converted nack to ASCII:  Hello World

How to convert ASCII text to decimal bytes?

bytes can work as iterable of ints, so you might create list from text converted to bytes following way

text = "Hello World"
values = list(text.encode("ascii"))
print(values)

gives output

[72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100]
