Python String to bytes
Python String to bytes conversion can be done in two ways:
- Using bytes() constructor and passing string and encoding as argument.
- Using encode() method on string object.
Python bytes to String
We can convert bytes to String using bytes class decode() instance method.
Let’s look at examples of converting a string to bytes and then bytes to string in a python program.

s="abc" # string to bytes using bytes() b = bytes(s, encoding='utf-8') print(type(b)) print(b) # bytes to string using decode() s = b.decode() print('Original String =', s) s="xyz" # string to bytes using encode() b = s.encode(encoding='utf-8') print(b) s = b.decode() print('Original String =', s) |

Best way to convert a string to bytes
Both the ways to convert a string to bytes are perfectly fine. String encode() and decode() method provides symmetry whereas bytes() constructor is more object-oriented and readable approach. You can choose any of them based on your preference.
