What is linear probing in hash table?
Linear probing is a scheme in computer programming for resolving collisions in hash tables, data structures for maintaining a collection of key–value pairs and looking up the value associated with a given key. It was invented in 1954 by Gene Amdahl, Elaine M.

What does __ hash __ do in Python?
The hash() method returns the hash value of an object if it has one. Hash values are just integers that are used to compare dictionary keys during a dictionary look quickly.
How do you handle collisions in a hash table in Python?
In open addressing, hash collisions are resolved by probing (explained below) . The hash table is just a contiguous block of memory (like an array, so you can do O(1) lookup by index). Each slot in the hash table can store one and only one entry. This is important.
