python如何打印99乘法表

# 九九乘法表
for i in range(1, 10):
    for j in range(1, i+1):
        print('{}x{}={}\t'.format(j, i, i*j), end='')
    print()

# 九九乘法表
i = 1
while i <= 9:
    j = 1
    while(j <= i):    # j的大小是由i来控制的
        print(&#39;%d*%d=%-3d&#39; % (i, j, i*j), end=&#39;\t&#39;)
        j += 1
    print(&#39;&#39;)
    i += 1

i = 1
while(i <=9):
    for j in range (1,i+1): #range()函数左闭右开
        print(&#39;%d*%d=%-3d&#39;%(i,j,i*j),end=&#39;&#39;)
    i += 1
    print()

for i in range(1,10):
    j = 0
    while j < i:
        j += 1
        print("%d*%d=%-3d"%(i,j,i*j),end=&#39;&#39;)
    print( )

a = [1, 2, 3, 4, 5, 6, 7, 8, 9]
for i in a:
    j = 1
    while j <= i:
        print(&#39;%d*%d=%-3d&#39;%(i,j,i*j),end=&#39;\t&#39;)
        # %-3d 是控制输出结果占据3位，且从左面开始对齐
        j += 1
    print( )

print('\n'.join([' '.join(["%2s x%2s = %2s" % (j, i, i*j) for j in range(1, i+1)]) for i in range(1, 10)]))
