n = 10

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

Program

# Python program to generate and print 
# dictionary of numbers and square (i, i*i)

# declare and assign n
n = 10

# declare dictionary 
numbers = {}

# run loop from 1 to n 
for i in range(1, n+1):
	numbers[i] = i * i

# print dictionary 
print numbers

Output

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