We want to store the key-value pair dynamically. # Python program to demonstrate # dynamic dictionary creation # Initialize an empty dictionary D = {} L = [ ['a', 1], ['b', 2], ['a', 3], ['c', 4]] # Loop to add key-value pair # to dictionary car runs better after resetting ecu WebPython Dictionary Comprehension - Example 1 Let's say we have a list of customers who visit our store, and we'd like to offer a random discount to each customer.
