Python implementation of multiplication table

Outer loop control line number, inner loop control output

1) While loop realizes multiplication table

1 j = 1
2 while j < 10:
3     i = 1
4     while i <= j:
5         print("{} * {} = {:{}}".format(i,j,i*j,2),end=" ")
6         i += 1
7     print()
8     j += 1

Output result == 》
 1 * 1 = 1 
1 * 2 = 2 2 * 2 = 4 
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9 
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16 
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49 
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64 
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81

2) For loop to achieve multiplication table

1 for i in range(1,10):
2     for j in range(1,i+1):
3         print("{} * {} = {:>2}".format(j,i,j*i),end=" ")
4     print()

Output result ==》
1 * 1 = 1 
1 * 2 = 2 2 * 2 = 4 
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9 
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16 
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49 
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64 
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
