今天给同学用思维导图整理了python基础知识,供大家复习参考学习,希望每天都有进步。
最后增加了列表推导式的案例和使用,学会了一定很香!
鸡汤几点:
没有目标永远不知道方向在哪?
不去尝试永远不知道答案和结果?
打破习惯、冲击惯性思维、不断学习,才能使你越来越有价值。
行动永远比坐以待毙更幸运。

新增列表推导式应用案例
一、Python简介:
二、输入和输出:
三、变量、数据基本类型与操作:
四、条件判断:
五、常用数据类型-列表
六、常用数据类型- 元组、字典
七、常用数据类型- 布尔值
八、循环语句
九、函数
十、类与对象
十一、编码与文件读写
十二、模块与库
十三、总结思维过程
总结思维过程:解决问题、实现目标。基本思路:
1、明确目标,定位问题
2、分析过程,拆解问题;如果没有更好的办法可以先以实现为主
3、逐步执行、各个击破
4、参考官方文档、博客找答案
5、根据以往经验编写出逻辑函数
补充:常见的错误类型
列表推导式案例1:有如下接口返回结果,需要取出data列表的指定参数(比如取出appNames为auto_zabbix的id)?
{"result":"success","message":null,"data":[{"id":"035548f3-d48d-45ba-8d37-da00ab757134","description":"auto_1649842493455","owner":"246283097","createTime":1649842494625,"updateTime":1649842494625,"deleted":0,"status":"ACTIVE","priority":6341,"reporter":"yangkai","assignor":"","project":"DEMO","triggerPriority":"2","issueTypeId":"10004","triggers":[{"id":"728c329c-5932-494c-bb31-4d938e721685","triggerId":"035548f3-d48d-45ba-8d37-da00ab757134","app":"62d520d39bcb41c78643b77fe87a9682","createTime":1649842494625,"updateTime":1649842494625,"deleted":0,"priority":6341,"exps":[],"apps":["62d520d39bcb41c78643b77fe87a9682"],"appNames":["auto_prometheus"]}]},{"id":"427ec5d6-f3c0-49b1-ba6f-f4c22b96e00c","description":"auto_1649842491891","owner":"246283097","createTime":1649842494276,"updateTime":1649842494276,"deleted":0,"status":"ACTIVE","priority":7413,"reporter":"yangkai","assignor":"","project":"DEMO","triggerPriority":"2","issueTypeId":"10004","triggers":[{"id":"416d462f-c9d3-40bf-a912-48cb599ed1d0","triggerId":"427ec5d6-f3c0-49b1-ba6f-f4c22b96e00c","app":"8db5c50e1d8f4dfe96d537439bbc9cec","createTime":1649842494276,"updateTime":1649842494276,"deleted":0,"priority":7413,"exps":[],"apps":["8db5c50e1d8f4dfe96d537439bbc9cec"],"appNames":["auto_zabbix"]}]},{"id":"e4ac27bc-296e-4360-b191-3d171359ec8c","description":"auto_jira","owner":"246283097","createTime":1649661923493,"updateTime":1649842165186,"deleted":0,"status":"ACTIVE","priority":12,"reporter":"yangkai","assignor":"","project":"DEMO","triggerPriority":"2","issueTypeId":"10004","triggers":[{"id":"76084cb6-04a2-46b3-b0a6-d2ae8ad8176e","triggerId":"e4ac27bc-296e-4360-b191-3d171359ec8c","app":"76e554415c024713a50f199fa6d9ef7e","createTime":1649661923493,"updateTime":1649661923493,"deleted":0,"priority":12,"exps":[],"apps":["76e554415c024713a50f199fa6d9ef7e"],"appNames":["auto_dynatrace"]}]}],"totalCount":0,"code":200}
这种结果使用列表推导式就很香了,返回结果肯定是列表了:
**zabbix_id**= [rule_json['data'][x]['id'] for x in range(len(rule_json['data'])) if
rule_json['data'][x]['triggers'][0]['appNames'][0] == 'auto_zabbix']
以上内容就是这些,一定对同学有所帮助!
