python - 我的python代码出现问题

Question

anwser=str(input("Do you need a new phone? "))

if answer== "no":   
    print ("You are now finished. ")
else:    
    question1=str(input("Do you know what phone you want? ")
    if question1== "no":
        print("Research different phones and chose which pne you like best.")
    else:
        question2=str(input("Do you want to go on a contract? ")
        if question2== "no": 
             question3=str(input("Do you have enought money to pay full price for your phone? ")

怎么了？我该如何改善？它不断出现语法错误，我不知道为什么。

Answer 1

您在问题线上缺少右括号:

question1 = str(input("Do you know what phone you want? ")

应该:

question1 = str(input("Do you know what phone you want? "))

您也不需要将输入转换为字符串，因为 input() 已经为您做到了:

input([prompt])

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that.
