您如何打印輸入的內容？

Question

我正在編寫一段代碼，詢問用戶的名字，名字，年齡，但是隨后我將其打印出來，但是我不確定如何給出答案。

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。

您可以這樣使用它：

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

或者在Python 3.6以上版本中，您可以使用以下速記：

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))

您可能要考慮將%s用作字符串，將%d用作數字，盡管;-)

Answer 3

Python中的新樣式字符串格式：

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

Answer 4

這是固定的代碼：

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.")

這很容易理解，因為它僅使用串聯。

Answer 5

有兩種格式化輸出字符串的方式：

• 舊方法

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

• 新方式（首選方式）

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

新方法更加靈活，並提供了一些小巧的便利，例如為占位符提供索引。 您可以在這里找到所有的區別和優點： PyFormat
