Python循环打印九九乘法表

使用for循环打印

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

使用while循环打印

i = 1
while i < 10:
    j = 1
    while j <= i:
        print(i, "*", j, "=", i * j, end="t")
        j += 1
    i += 1
    print()

使用单层循环打印

i = 1
j = 1
while i <= 9:
    print(i, "*", j, "=", i * j, end="t")
    if i == j:
        i += 1
        j = 1
        print()
    else:
        j += 1
