Method 1: Using a Simple Loop One of the most straightforward ways to find a key by its value in a Python dictionary is to use a simple loop. This method involves iterating through the dictionary items, checking each value against the target value, and returning the corresponding key when ...
1. Dictionary Intersection using ‘&’ Operator The simplest method to find the intersection of keys, values or items is to use&(ampersand) operator between two dictionaries. This operator creates a new dictionary containing only the key-value pairs that are common to both dictionaries. In the ...

To find the maximum value in the record list as tuple attribute, we will loop on the list of tuples and for each tuple find the maximum value amongst the elements of the array and return their pairs as tuples to result. In Python, we can perform the task in multiple ways using one ...
