Pipe PuTTY console to Python script

由 主宰稳场 提交于 2021-02-20 05:15:37
问题 I am trying to launch a PuTTY window that establishes a serial connection, and then have the main cmd window (the one that launched my Python script) control the PuTTY window. The PuTTY window will still be open and showing everything, but I want to disable the stdin on it and just have it get the input from the cmd shell. So I have it successfully launching the PuTTY window, just cant seem to pipe my outputs and inputs like I want. Any help would be greatly appreciated! Code for launching

MySQL：视图、触发器、存储过程、事务

视图： 视图，虚拟表 创建虚拟表： # 语法： # create view 虚拟表名称 as 虚拟表; create view course_and_teacher as select * from course inner join teacher on course.teacher_id = teacher.tid; # 虚拟表在硬盘上存储时，只有 表结构， 没有 表数据 那张表，即 只有 course_and_teacher.frm 这个文件；因为虚拟表的数据来自于其它表 # 创建的虚拟表可以直接使用： select * from course_and_teacher; # 每次使用 course_and_teacher 这张表时，都会触发 select * from course inner join teacher on course.teacher_id = teacher.tid; # 虚拟表不建议使用，因为 如果 你在数据库建了大量的视图，不利用扩展（数据库可能经常需要扩展；即强耦合）；所以尽量用原生的 SQL # 另外，视图是用来查询的，不能用来修改（不要修改视图中的记录） # 修改视图： # 语法： alert view 视图名称 as SQL语句; alert view course_and_teacher as select * from course

What is the correct graph data structure to differentiate between nodes with the same name?

由 廉价感情. 提交于 2021-02-20 05:14:13
问题 I'm learning about graphs(they seem super useful) and was wondering if I could get some advice on a possible way to structure my graphs. Simply, Lets say I get purchase order data everyday and some days its the same as the day before and on others its different. For example, yesterday I had an order of pencils and erasers, I create the two nodes to represent them and then today I get an order for an eraser and a marker, and so on. After each day, my program also looks to see who ordered what,

How to Divide the Contents of a TkInter Entry With a Number?

由 家住魔仙堡 提交于 2021-02-20 05:14:01
问题 I've been trying to figure out how to divide the contents of a TkInter entry box with a number (a float, to be precise). I looked it up on Google, and I found nothing that answered my question, other than doing .get() for getting a number from a entry. I want to have a number already there (or have a static variable) that I can divide to get the results I need. Any help would be appreciated! Thanks a billion!! :D P.S. Here's the website results I saw before I posted this question: Results of

Find all numbers that sum closest to a given number python

由 我只是一个虾纸丫 提交于 2021-02-20 05:13:37
问题 I have a script below that gives the closest 2 values to a given sum. It also iterates through a list of given sums and after each iteration removes the numbers that have already been used. I need to modify this script so that it produces a necessary amount of values closest to each sum, rather than 2. The script needs to accept float values and cannot re-use values. Effectively it needs to pick the most efficient set closest to target, update the set to remove values used, then move on to

Convert JIS X 208 code to UTF-8 in Python

问题 Let's say I have this Kanji "亜" which is represented in JIS X 208 code in hex form: 0x3021. I want my Python program to convert that code into its UTF-8 form E4BA9C so that I can pass that string (URL-encoded) into my url like this http://jisho.org/api/v1/search/words?keyword=%E4%BA%9C I'm using Python 2.7.12 but I'm open to Python 3 solution as well 回答1: These are accessed under ISO 2022 codec. >>> '亜'.encode('iso2022_jp') b'\x1b$B0!\x1b(B' If I saw those bytes not framed by the escape
