如何在Python中创建带换行符的字符串？

Question

我有一条短信：

  

没有你的聪明嘴我该怎么办？
  吸引我，你把我踢出去
  你的头在旋转，没有开玩笑，我无法把你固定下来
  那个美丽的心灵发生了什么
  我在你神奇的神秘旅程中
  而且我很头晕，不知道是什么打了我，但我会没事的

...现在我要使用此文本创建一个字符串。例如在Python中：

string = " What would I do without your smart mouth?
Drawing me in, and you kicking me out
You've got my head spinning, no kidding, I can't pin you down
What's going on in that beautiful mind
I'm on your magical mystery ride
And I'm so dizzy, don't know what hit me, but I'll be alright "

但是Python并不认为这是字符串，因为它包含换行符。如何使该文本成为字符串？

Answer 1

使用三引号

您可以使用三引号（"""或'''）来指定带换行符的字符串：

string = """What would I do without your smart mouth?
Drawing me in, and you kicking me out
You've got my head spinning, no kidding, I can't pin you down
What's going on in that beautiful mind
I'm on your magical mystery ride
And I'm so dizzy, don't know what hit me, but I'll be alright"""

如the documentation所述：

  

字符串文字可以跨越多行。一种方法是使用三引号："""..."""或'''...'''。行尾自动包含在字符串[...]

中

使用\n

您还可以在字符串中显式使用换行符（\n）来创建换行符：

string = "What would I do without your smart mouth?\nDrawing me in, and you kicking me out\nYou've got my head spinning, no kidding, I can't pin you down\nWhat's going on in that beautiful mind\nI'm on your magical mystery ride\nAnd I'm so dizzy, don't know what hit me, but I'll be alright"

Answer 2

通过以下代码行：

value = '''
    String
    String
    String
    '''

---

value = """
    String
    String
    String
    """

---

value = 'String\nString\nString'

---

value = "String\nString\nString"

---

输出与以上代码行相同：

>>> print value
String
String
String

---

最简单的方法是对它进行三重引用：

string = '''What would I do without your smart mouth?
Drawing me in, and you kicking me out
You've got my head spinning, no kidding, I can't pin you down
What's going on in that beautiful mind
I'm on your magical mystery ride
And I'm so dizzy, don't know what hit me, but I'll be alright'''
