Day 99 : Python Program to Create Dictionary that Contains Number

 numbers = [1, 2, 3, 4, 5]

number_dict = {}

for num in numbers:

    number_dict[num] = num ** 2 

print("Dictionary with numbers and their squares:", number_dict)

Code Explanation:

Input List:

numbers = [1, 2, 3, 4, 5]

This list contains the numbers for which we want to calculate the square.

Create an Empty Dictionary:

number_dict = {}

This empty dictionary will be populated with key-value pairs, where:

The key is the number.

The value is the square of the number.

Iterate Through the List:

for num in numbers:

This loop iterates through each number (num) in the numbers list.

Compute the Square of Each Number and Add It to the Dictionary:

number_dict[num] = num ** 2

num ** 2 calculates the square of the current number.

number_dict[num] assigns the square as the value for the current number (num) in the dictionary.

Print the Dictionary:

print("Dictionary with numbers and their squares:", number_dict)

This displays the resulting dictionary, which contains each number and its square.
