Python错误 - TypeError：输入最多需要1个参数，得到3

Question

有人可以解释为什么我不能在目标变量中使用your_name吗？

my_name = "Bryson"
my_age = 29
your_name = input ("What is your name? ")
your_age = input ("What is your age? ")
print ("My name is", my_name,", and I am", my_age, "years old.")
print ("Your name is", your_name,", and you are", your_age,".")
print("Thank you for buying my book,", your_name,"!")
goal = input ("What was your favorite part of the book,", your_name, "?")
print("Awesome!")

我得到的错误是：

goal = input ("What was your favorite part of the book,", your_name, "?")
TypeError: input expected at most 1 arguments, got 3

Answer 1

你得到了这个错误，因为你实际上只给了input函数3个参数，当它只期望1时（即字符串提示符）。

In input ("What was your favorite part of the book,", your_name, "?")
           ---------------------------------------- , ---------, ---

带下划线的部分是以逗号分隔的参数：一个字符串（＆＃34;什么是.... book＆＃34;，一个变量your_name，另一个字符串，＆＃34;？＆＃ 34;

我认为你想要的是

goal = input("What was your favorite part of the book, " + your_name + "?")

这里连接运算符+将这些成分组合成一个字符串 - 字符串是input期待的一个参数

Answer 2

试试这个：

goal = input ("What was your favorite part of the book, %s ?" % your_name)

Answer 3

input(print("What was your favorite part of the book, " + your_name + "?"))
