import zlib
import base64

def gzdeflate(string):
    compressed_data = zlib.compress(string)[2:-4]
    return base64.b64encode(compressed_data)

OR a bit longer but much correct way at same time (python 3):

import zlib
# bytes('some string', encoding='utf-8') to convert string to bytes (an encoding may differs)
def gzdeflate(data: bytes) -> bytes: 
    compressor = zlib.compressobj(9, zlib.DEFLATED, -zlib.MAX_WBITS)
    compressed = compressor.compress(data)
    compressed += compressor.flush()
    return compressed
#output is raw compressed data, you can encode it to base64 by
