Solution:

Write a Python script to print a dictionary where the keys are numbers between 1 and 20 (both included) and the values are square of keys.

Flowchart:

Python Code:

d=dict()

for x in range(1,21):

d[x]=x**2

print(d)

Output:

{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64, 9: 81, 10: 100, 11: 121, 12: 144, 13: 169, 14: 196, 15: 225, 16: 256, 17: 289, 18: 324, 19: 361, 20: 400}
