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{}={}	'.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('%d*%d=%-3d' % (i, j, i*j), end='	')
 j += 1
 print('')
 i += 1

i = 1
while(i <=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 range(1,10):
 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='	')
 # %-3d 是控制输出结果占据3位，且从左面开始对齐
 j += 1
 print( )

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