Python : Convert(cast) string to bytes example

Problem :

You have couple of string variables in Python and you want to convert or type cast the string variables to bytes. How to do that?

Solution :

For Python 3 :

Declare a string variable and find out the variable type with type(var)

 var = "str"
 <class 'str'> // type string

Convert string type to bytes with encode() function

 var = "str".encode()
 <class 'bytes'> // type bytes

Alternatively, you can convert or type cast the string into bytes...straightaway by adding the b character pre-fix.

 var = b"str"
 <class 'bytes'> // type bytes
