问一个Q，并得到一个csv文件？ [英] asking a Q and get it out of a csv file?

问题描述

Q = question

Q = question

我想从csv文件访问信息，例如，如果该文件包含：

I want to access information from a csv file, for example if the file included:

NAME|DATE OF BIRTH|PHONE NUMBER|

 xxx|yyyyyyyyyyyyy| zzzzzzzzzzz|

 xxx|yyyyyyyyyyyyy| zzzzzzzzzzz|

 xxx|yyyyyyyyyyyyy| zzzzzzzzzzz|

我如何提出一个问题，例如：

How would I ask a question, example:

（伪码）

您要查找的人的姓名是什么？

(pseudo code)
what is the name of the person you are looking for? :

并且为了让python得到信息并显示它？

And for python to get the information and display it?

推荐答案

p>没有为你编写所有代码...

Without writing all your code for you...

将你的问题分解成你需要实现的不同组件：

Break your problem down into the different components you need to implement:

• 阅读 a < a href =http://docs.python.org/3/library/csv.html =nofollow>。CSV 文件


• 整理数据检索（一个或多个 dicts ，可以用来查找记录的每个字段）可能是最简单的解决方案）


• 获取用户 input （提出问题）


• 检索所请求的数据


• 向用户显示请求的数据

• Read a .CSV file
• Organize the data for retrieval (one or more dicts, keyed by each field you might want to use to look up records, is probably the simplest solution)
• Get user input ("ask a question")
• Retrieve the requested data
• Display the requested data to the user

研究）如何单独实现这些，然后你可以编写你的程序来做到这一点。如果您对某个特定作品有特定问题，请使用您撰写的程式码回到SO，并说明您遇到的问题。

Figure out (i.e. research) how to implement each of these individually, and then you can write your program to do that. If you then have a specific problem with a specific piece, come back to SO with the code you've written and explain the trouble you're having.
