Question

import os.path

#The model of the phone initialised to empty
strModel = ""

#Ask the user for their make
strModel = input("What is the make?")

#if the length of their input is too small ask them to input again
while len(strModel) <= 4:
    #Promot the user to input again
    strModel = input("Not enough characters. What is the make?")

#check if the file exists for specified phone    
if os.path.isfile(strModel + ".txt") == True:
    #open the file
    f = open(strModel + ".txt", "r")
    #turn contents of file into an array of strings for each line
    lineArray = f.readlines()

    #loop through the array to ask and answer questions
    for line in lineArray:
        #check if the line we are on is a question
        if lineArray.index(line) % 2 == 0 or lineArray.index(line) == 0:
            question = line
            #ask the question and wait for reply
            userAnswer = input(question)
            #yes means the user has that problem so print the relevant answer
            if(userAnswer == "yes"):
               print(lineArray[lineArray.index(line)+1])
else:
    print("Your model does not exist in our database.")

我是Python的初学者。我该如何为这段代码编写伪代码。这是向用户询问手机的代码。如果我能以什么方式进行，那么我对这段代码的效率会更高吗？

我会告诉你我是怎么做到的;我这样做的主要原因是我不是编译器。另外......在编程课上我跳过那一周，因为我想编写＆＃34;真实代码＆＃34;。

通常，您编写伪代码来规划实际代码的编写。但是，像python IMO这样的语言并没有必要。

反正;我想到了算法或工作流程，无论我做什么;也许它是一个功能;如果它是一个函数，我会想到我需要执行该函数，然后快速表示它（伪代码）然后转换为实际代码。当然，我不是这样做的......除非是面试（因为，我不是编译/翻译/等）;大多数面试官都不关心工作代码，他们希望看到你知道数据结构等。

对于你的代码，我在伪代码中会这样想：

strModel <= input

while strModel <= 4:
    prompt

if path_is_valid:
    fd = open file

    for each line in file:
         if this or that:
             prompt user

             if answer is yes:
                 do that

此代码的伪代码
