I am trying to Compress a string in python 3.6.3 using zlib, but getting an error(TypeError: a bytes-like object is required, not 'str') , it was supposed to work on python 2.7- versions, here is my simple code:

import zlib

a='hellohellohelloheeloohegregrf'

b=zlib.compress(a)

print(b)

python-3.x compression zlib

import zlib

a='hellohellohelloheeloohegregrf'

b=zlib.compress(a.encode("utf-8"))

print(b)

Alternative:

import zlib

a= b'hellohellohelloheeloohegregrf'

b=zlib.compress(a)

print(b)

In Python2.x this string literal is called a str object but it's stored as bytes.

In Python3.x this string literal is a str object and its type is Unicode. So, one need to prefix it with b or use .encode to get bytes object.

import zlib

b=zlib.compress(a.encode("utf-8"))

print(b)

In Python2.x this string literal is called a str object but it's stored as bytes.

In Python3.x this string literal is a str object and its type is Unicode. So, one need to prefix it with b or use .encode to get bytes object.
