The minimal syntax for dictionary comprehension is: dictionary = {key: value for vars in iterable} Let's compare this syntax with dictionary comprehension from the above example. Now, let's see how we can use dictionary comprehension using data from another dictionary. Example 3: How to use ...
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) Output {1: 'python', 2: 'c', 3: 'c++'} This example is similar to Example 1; the only difference is that...
