输出0~99,每行10个,一共10行

sum =[]
j=0

for i in range(100):
    sum.append(i)

for i in range(100):
    print (str(sum[i])+'  ',end='')
    j = j+1
    if j%10 == 0:# %10表示10个数字一行
        print()

或者不用数组,如下:

j=0

for i in range(100):
    print (str(i)+'  ',end='')
    j = j+1
    if j%10 == 0:# %10:10个数字一行
        print()
