Thezip()function in Python is used to combine two lists into a single list of tuples, where the first element of the tuple contains the elements of first list, the second element of the tuple contains the element from second list and pass this as an input to dict() constructor to creat...
Example 2: Using list comprehension index = [1, 2, 3] languages = ['python', 'c', 'c++'] dictionary = {k: v for k, v in zip(index, languages)} print(dictionary) Run Code Output {1: 'python', 2: 'c', 3: 'c++'} This example is similar to Example 1; the only differenc...
A dictionary comprehension is a concise way to create a list by iterating over an iterable, such as a dictionary. so You can also merge multiple dictionaries in Python by using adictionary comprehension. # Use comprehension merged_states= {k: v for d in (states_1, states_2) for k, v ...
Write a Python program to interleave two lists into another list randomly. Use the map() function. Sample Solution: Python Code: # Import the 'random' moduleimportrandom# Define a function named 'randomly_interleave' that takes two lists as inputdefrandomly_interleave(nums1,nums2):# Create a...
Write a Python program to combine multiple dictionaries into one by appending values for duplicate keys into lists. Write a Python program to iterate over multiple dictionaries and construct a new dictionary where each key’s value is a list of all corresponding values. ...
For a more concise solution or to create a list of matching keys, the list comprehension method is a good choice. How do I check if a dictionary has the same value in Python? Here are two ways to interpret “same value” in a dictionary context: ...
Original dictionaries... dict_1: {'x': 1, 'y': 2} dict_2: {'a': 3, 'b': 4} Merged dictionary... {'x': 1, 'y': 2, 'a': 3, 'b': 4} Merge more than two dictionaries in a single lineThe above can be used to merge two or more dictionaries, like below,...
