Decompress gz compressed string using Python3.6

Question

I want to decompress the following gz compressed string using python3.6:

H4sIAAAAAAAA//NIzcnJVwjPL8pJAQBWsRdKCwAAAA==

The decompressed string is "Hello World"

I was able to decompress it using online tool - http://www.txtwizard.net/compression but I couldn't find a proper way to do it in python.

I tried zlib and gzip, but they require bytes not str. I also tried converting it using io.Bytes() but of no use. My Code is:

import gzip
import io 

class SearchEvents:

def decompressPayload():
    payload = "H4sIAAAAAAAA//NIzcnJVwjPL8pJAQBWsRdKCwAAAA=="
    payload_bytes = io.BytesIO(payload)
    print(gzip.decompress(payload_bytes))

SearchEvents.decompressPayload()

I am expecting "Hello World" as output. But I am getting the following error:

Traceback (most recent call last):
File "SearchEvents.py", line 13, in <module>
SearchEvents.decompressPayload()
File "SearchEvents.py", line 10, in decompressPayload
payload_bytes = io.BytesIO(payload)
TypeError: a bytes-like object is required, not 'str'

Is there any way to achieve what I want?

...==

That's not a gzip-compressed string. At least, not until you Base64-decode it first.

>>> gzip.decompress(base64.b64decode('H4sIAAAAAAAA//NIzcnJVwjPL8pJAQBWsRdKCwAAAA=='))
b'Hello World'
