Question

我正在编写一段代码，询问用户的第一个名字，然后是第二个名字，然后是他们的年龄，然后我将其打印出来，但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

您想使用string.format。

你这样使用它：

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

或者在Python 3.6中，您可以使用以下简写：

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

Answer 2

使用

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

您可能需要考虑使用%s作为字符串，%d作为数字; - ）

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，因为这只是使用连接。

Answer 5

有两种格式化输出字符串的方法：

旧方式

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，并提供简单的便利，例如为占位符提供索引。您可以在此处找到所有差异和优势：PyFormat
