python—用for循环、while循环和一句话打印九九乘法表，,用for循环打印九九

用for循环打印九九乘法表：

for i in range(1,10):    for j in range(1,i+1):        print(‘%s*%s=%s‘%(j,i,i*j),end=‘\t‘)    print()

　　打印结果

1*1=11*2=22*2=41*3=32*3=63*3=91*4=42*4=83*4=124*4=161*5=52*5=103*5=154*5=205*5=251*6=62*6=123*6=184*6=245*6=306*6=361*7=72*7=143*7=214*7=285*7=356*7=427*7=491*8=82*8=163*8=244*8=325*8=406*8=487*8=568*8=641*9=92*9=183*9=274*9=365*9=456*9=547*9=638*9=729*9=81

　　while循环打印九九乘法表：

i=0j=0while i<9:    i+=1    while j<9:        j+=1        print(j,"x",i,"=",i*j,"\t",end="")        if i==j:            j=0            print("")            break

　　打印结果是：

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

　　用一句话打印九九乘法表：

print (‘\n‘.join([‘ ‘.join([‘%s*%s=%-2s‘ % (y,x,x*y) for y in range(1,x+1)]) for x in range(1,10)]))

　　打印结果是：

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