python的print换行与不换行

print不换行

• 不换行

>>>print('hello',end='')#一个空代表不换行相连
>>>print('world')
helloworld
>>>print('hello',end=' ')#两个空代表不换行有间隔
>>>print('world')
hello world
>>>print('hello',end='!')#！代表不换行以！相连
>>>print('world')
hello!world

• 换行

>>>for i in range(1，3):
>>>	print('{} x2 = {}'.format(i,1*i),end=' ')
>>>print('')
>>>for i in range(1,4):
>>>	print('{} x3 = {}'.format(i,1*i),end=' ')
>>>
1 X 2 = 2  2 X 2 = 4  
1 X 3 = 3  2 X 3 = 6  3 X 3 = 9

	

一个小练习：打印九九乘法表

>>>for i in range(1,10):
>>>	for j in range(1,i+1):
>>>		print('{} x{} = {}'.format(j,i,i*j),end=' ')
>>>	print('')	

• 结果为
