Found myself :

import struct
def leftrotate(i, n):
return ((i << n) & 0xffffffff) | (i >> (32 - n))
class SHA1(object):
def __init__(self, data=b""):

self.remainder = data
self.count = 0

self.count += 1
w = list( struct.unpack(">16I", chunk) + (None,) * (80-16) )
for i in range(16, 80):
n = w[i-3] ^ w[i-8] ^ w[i-14] ^ w[i-16]
w[i] = leftrotate(n, 1)
a,b,c,d,e = self.h

#FIXED

self.add( b"\x80" + b"\x00" * ((55 - l) % 64) + ll2 )
h = tuple(x for x in self.h)
self.__init__()
return struct.pack(">5I", *h)
def main():
s=SHA1(b"test")
print(s.finish())
if __name__ == '__main__':
main()
So now have websocket working !!!
Cheers
