您如何打印输入的内容？

Question

我正在编写一段代码，询问用户的名字，名字，年龄，但是随后我将其打印出来，但是我不确定如何给出答案。

print ("What is your first name?"),
firstName = input()
print ("What is you last name?"),
secondName = input()
print ("How old are you?")
age = input()

print ("So,  you're %r  %r and you're %r years old."), firstName, secondName, age

Answer 1

您要使用string.format。

您可以这样使用它：

print ("So, you're {} {} and you're {} years old.".format(firstName, secondName, age))

或者在Python 3.6以上版本中，您可以使用以下速记：

print (f"So, you're {firstName} {secondName} and you're {age} years old.")

Answer 2

采用

print ("So, you're %r  %r and you're %r years old." % (
    firstName, secondName, age))

您可能要考虑将%s用作字符串，将%d用作数字，尽管;-)

Answer 3

Python中的新样式字符串格式：

print("So, you're {} {} and you're {} years old.".format(firstName, secondName, age))

Answer 4

这是固定的代码：

firstName = input("What is your first name?")
secondName = input("What is you last name?")
age = input("How old are you?")

print ("So,  you're " + firstName + " " + secondName + " and you're " + age + " years old.")

这很容易理解，因为它仅使用串联。

Answer 5

有两种格式化输出字符串的方式：

• 旧方法

   print("So, you're %s %s and you're %d years old." % (firstName, secondName, age) 

• 新方式（首选方式）

   print("So, you're {} {} and you're {} years old.".format(firstName, secondName, age)) 

新方法更加灵活，并提供了一些小巧的便利，例如为占位符提供索引。 您可以在这里找到所有的区别和优点： PyFormat
