Python Program to Map two lists into a Dictionary

Write a Python Program to Map two lists into a Dictionary with a practical example.

Python Program to Map two lists into a Dictionary Example 1

In this python program, we are using for loop with zip function.

keys = ['name', 'age', 'job']
values = ['John', 25, 'Developer']

myDict = {k: v for k, v in zip(keys, values)}
print("Dictionary Items  :  ",  myDict)

Python Program to insert two lists into a Dictionary Example 2

This code is another approach to inserting lists into a Dictionary. In this Python program, we use a dict keyword and zip function.

keys = ['name', 'age', 'job']
values = ['John', 25, 'Developer']

myDict = dict(zip(keys, values))
print("Dictionary Items  :  ",  myDict)

Map two lists into a Dictionary output

Dictionary Items  :   {'name': 'John', 'age': 25, 'job': 'Developer'}
>>> 

Program to map two lists into a Dictionary Example 3

This map two lists into a Dictionary code is the same as above. However, in this python program, we are allowing the user to insert the keys and values.

keys = []
values = []
num = int(input("Please enter the Number of elements for this Dictionary : "))
print("Integer Values for Keys")
for i in range(0, num):
    x = int(input("Enter Key " + str(i + 1) + " = "))
    keys.append(x)
    
print("Integer Values for Values")
for i in range(0, num):
    x = int(input("Enter Value " + str(i + 1) + " = "))
    values.append(x)
    
myDict = dict(zip(keys, values))
print("Dictionary Items  :  ",  myDict)

Please enter the Number of elements for this Dictionary : 3
Integer Values for Keys
Enter Key 1 = 2
Enter Key 2 = 4
Enter Key 3 = 6
Integer Values for Values
Enter Value 1 = 50
Enter Value 2 = 100
Enter Value 3 = 150
Dictionary Items  :   {2: 50, 4: 100, 6: 150}
