Although cPython and Redis hashtables are both implemented in C. cPython's open addressing based hashtable[1] is far superior to the simple chaining based hashtable[2] in Redis. Python's performance is heavily dependent on the performance of its hash table implementation that it has been optimized over and over decades now.
