Python Map Array To Dict

2) using ast.literal.eval() the ast.literal.eval() is an inbuilt python library function used to convert string to dictionary efficiently. Elements in numpy arrays are accessed by using square brackets and can be initialized by using nested python lists. Python program to map two lists into a dictionary example 1 in this python program, we are using for loop with zip function.

Given a list, write a python program to convert the given list to dictionary such that all the odd elements have the key, and even number elements have the value. Value for vars in iterable} see the following code example of dictionary. For this approach, you have to import the ast package from the python library and then use it with the literal_eval() method.

Dictionary comprehension is an elegant and concise way to create dictionaries.

A dictionary in python is created using curly brackets ( {}). Since python dictionary is unordered, the output can be in any order. This can have application in domains in which we require to reduce the data storage and in web development domain. Python lists and dictionaries are two structures used to store data.
