python 3.6.3. zlib compression












1















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.

But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
