for j in range(2 , i + 1):
print(' ' , j , "x" , i , "=%2d" % (i * j) , sep = '' , end = '')
print() # 为本行输出画上句号,空 print() 足矣,加 '\n' 属于画蛇添足,反而影响美观。
运行实况:>>> for i in range(1, 10):
print(1 , "x" , i , "=%2d" % i , sep = '' , end = '')
for j in range(2 , i + 1):
print(' ' , j , "x" , i , "=%2d" % (i * j) , sep = '' , end = '')
print()
