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 difference is that list comprehension is bei...
Write a Python program to convert a list into a nested dictionary of keys. Sample Solution: Python Code: # Create a list 'num_list' containing numbers.num_list=[1,2,3,4]# Create an empty dictionary 'new_dict' and initialize 'current' to reference the same dictionary.new_dict=current...
Write a Python program to convert a tuple to a dictionary. Visual Presentation: Sample Solution: Python Code: # Create a tuple containing nested tuples, where each inner tuple consists of two elements.tuplex=((2,"w"),(3,"r"))# Create a dictionary by using a generator expression to swap...
Convert Dictionary Values to List Python using for loop We can also use a for loop in Python to convert a dictionary value to a list. First, it will get the dict’s values using thevalues()method. Then, it will iterate over every value one by one and append it to the list using th...
