6. Generate Dictionary of Numbers and Their Squares

Write a Python script to generate and print a dictionary that contains a number (between 1 and n) in the form (x, x*x).

Sample Solution:-

Python Code:

# Prompt the user to input a number and store it in the variable 'n'.
n = int(input("Input a number "))

# Create an empty dictionary 'd' to store the square of numbers.
d = dict()

# Iterate through numbers from 1 to 'n' (inclusive).
for x in range(1, n + 1):
    # Calculate the square of each number and store it in the dictionary 'd' with the number as the key.
    d[x] = x * x

# Print the dictionary 'd' containing the squares of numbers from 1 to 'n'.
print(d)

Sample Output:

10                                                                                                            
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81, 10: 100}
