Convert binary to string using Python
• Last Updated : 14 Aug, 2020

Data conversion has always been widely used utility and one among them can be the conversion of a binary equivalent to its string.
Let’s discuss certain ways in which this can be done.

Method #1:

The naive approach is to convert the given binary data in decimal by taking the sum of binary digits `(dn)` times their power of `2*(2^n)`. The binary data is divided into sets of 7 bits because this set of binary as input, returns the corresponding decimal value which is `ASCII` code of the character of a string. This ASCII code is then converted to string using `chr()` function.

Note: Here we do slicing of binary data in the set of 7 because, the original ASCII table is encoded on 7 bits, therefore, it has 128 characters.

Output:

```The binary value is: 10001111100101110010111010111110011
The Binary value after string conversion is:  Geeks
```

Method #2: Using int() function
Whenever an `int()` function is provided with two arguments, it tells the `int()` function that the second argument is the base of the input string. If the input string is larger than 10, then Python assumes that the next sequence of digits comes from `ABCD...` .Therefore, this concept can be used for converting a binary sequence to string. Below is the implementation.

Output:

```The binary value is: 10001111100101110010111010111110011
The Binary value after string conversion is:  Geeks
