encoding text with binary

### tutorial: encoding text to binary

encoding text to binary involves converting characters into a format that a computer can understand and process. each character is represented by a binary number, typically using encoding standards like ascii or utf-8. in this tutorial, we’ll focus on ascii encoding and provide a python code example to demonstrate the process.

#### understanding ascii encoding

ascii (american standard code for information interchange) is one of the most common character encoding schemes. each character in the ascii table is represented by a 7-bit binary number, allowing for 128 unique characters, including:

- uppercase letters (a-z)
- lowercase letters (a-z)
- digits (0-9)
- punctuation marks
- control characters (e.g., newline, carriage return)

for example:
- the character 'a' is represented by the decimal number 65, which is `01000001` in binary.
- the character 'a' is represented by the decimal number 97, which is `01100001` in binary.

### encoding text to binary in python

below is a step-by-step guide to encoding a string of text into its binary representation using python.

#### step 1: define the function

we will create a function called `text_to_binary` that takes a string as input and returns its binary representation.

#### step 2: testing the function

now, we can test our function with a sample text:

#### complete code example

here’s the complete code that includes both the function and the test:

### explanation of the code

1. **function definition**: the `text_to_binary` function takes a string as input.
2. **character loop**: it iterates through each character in the string.
3. **ascii conversion**: for each character, it uses `ord(char)` to get the ascii value and `format(..., '08b')` to convert it to an 8-bit binary string.
4. **list of binary strings**: each binary string is appended to a list.
5. **joining the list**: finally, the list of binary strings is joined into a single string with spaces in between for ...
