python 输出字符串要注意的问题

case one ’ ’ 可以

print('a in ')

case two’ ’ ’ '不可以

print('a in 'a''.)

" " " " 不可以

print("a in "a" ")

case three " ’ ’ "可以

print("a in 'a'")

case four ’ " " ’ 可以

print('a in "a"')

case five ’ '换行 ’ ’ 结果都只变成一行，顺着下来

print('Hello ,I am hahahaha .I used to do '
	'somthing very interesting!')

case six " "换行 " " 结果都只变成一行，顺着下来

print("Hello ,I am hahahaha .I used to do "
	"somthing very interesting!")

case seven ’ '换行 " " 结果都只变成一行，顺着下来

print('Hello ,I am hahahaha .I used to do '
	"somthing very interesting!")

综上所述，case five ,six ,seven 的输出结果都是一样的。
