python如何打印99乘法表用python

# 九九乘法表
for i in range1, 10):
    for j in range1, i+1):
        print'{}x{}={}\t'.formatj, i, i*j), end='')
    print)

# 九九乘法表
i = 1
while i <= 9:
    j = 1
    whilej <= i):    # j的大小是由i来控制的
        print'%d*%d=%-3d' % i, j, i*j), end='\t')
        j += 1
    print'')
    i += 1

i = 1
whilei <=9):
    for j in range 1,i+1): #range)函数左闭右开
        print'%d*%d=%-3d'%i,j,i*j),end='')
    i += 1
    print)

for i in range1,10):
    j = 0
    while j < i:
        j += 1
        print"%d*%d=%-3d"%i,j,i*j),end='')
    print )

a = [1, 2, 3, 4, 5, 6, 7, 8, 9]
for i in a:
    j = 1
    while j <= i:
        print'%d*%d=%-3d'%i,j,i*j),end='\t')
        # %-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 range1, i+1)]) for i in range1, 10)]))
