Hashing a tuple not matching the expected value in python

Certainly! Hashing in Python involves converting data (like tuples) into a fixed-size string of characters that represent the original data. When a tuple doesn't match the expected hash value, it could be due to changes in its contents or structure. Below is a tutorial explaining this concept along with a code example in Python.
Hashing is a process to generate a fixed-size string (hash value) from data of arbitrary size. In Python, tuples are hashable objects, meaning they can be used as keys in dictionaries or elements in sets because their contents are immutable. The hash value of a tuple is computed based on its elements.
However, if the contents of the tuple change after it's hashed, the generated hash value will be different from the expected one. This occurs because tuples are immutable, so any change in their elements will create a new tuple instance with a different hash value.
Let's create a Python script that demonstrates hashing a tuple and how changing its contents affects the hash value.
In the example, changing the tuple's contents resulted in a different hash value. This demonstrates how even a slight modification to a tuple can affect its hash value, making it important to consider immutability when using tuples as keys in dictionaries or elements in sets.
Remember, when working with hashable objects like tuples in Python, any change to their content will produce a different hash value, impacting their use in data structures relying on hash values for lookup or comparison.
This tutorial provides an insight into understanding hash values of tuples and how modifications to tuple contents can influence their hashability and usage in hash-based collections.
