Nested For loop

9 x 9 multiply table

• By using 2 for (nested for) and print continuosly without line break to print a 9 x 9 multiply table.

Similar Pattern

• in n line, it always start with 1 * n = x; 2 * n = x; ... * n = ...x
• if n = 1, item in a row = 1 (n = number of items in a row)
• max row = 9

nested-for.py

# i = row, max i = 9
# range(x, y): return start: x end: y - 1 (y is not included)

for i in range(1, 10):
    for j in range(1, i + 1):
        print(f"{j}*{i}={i*j}\t", end="")
    print()
