Now we can convert the created my_tuples to a dictionary, which is a mutable object. Example 1: Transform List of Tuples to Dictionary via dict() FunctionIn this first example, we will use the Python dict() function to convert the list of tuples into a dictionary:...
And if you do need them as a list you can calllist().如果确实需要它们作为列表,则可以调用list()。 Very similarly forzip()-- in the vast majority of cases, it is iterated through -- why create an entire new list of tuples just to iterate through it and then throw it away again?与...
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...
