python怎麽打印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()

2、while-while

# 九九乘法表

i = 1

while i <= 9:

j = 1

while(j <= i): #j的大小是由i來控制的

print('%d*%d=%-3d' %(i, j, i*j),end='\t' )

j += 1

print('')

i += 1

3、while-for

i = 1

while(i <=9):

for j in range (1,i+1): #range()函數左閉右開

print('%d*%d=%-3d'%(i,j,i*j),end='')

i += 1

print()

4、for-while

for i in range(1,10):

j = 0

while j < i:

j += 1

print("%d*%d=%-3d"%(i,j,i*j),end='')

print()

5、定義壹個變量a

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 是控制輸出結果占據3位，且從左面開始對齊

j += 1

print()

6、使用1行語句

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)]))
