Squerly从嵌套的dict和list中去掉了单调乏味的内容。
squerl的Python项目详细描述
概述
让在python字典和列表的嵌套中四处挖掘变得不那么乏味。在
动机
假设您有一堆这样的yaml文档（为了简洁起见，截取了一些数据）：
计划程序：

你想知道在最新版本中，哪些节点没有提到节点状态。在
你可以这样做：
defget_stale(resources):results=[]fordocinresources:forstatusindoc.get("status",{}).get("nodeStatuses",[]):if"targetRevision"instatusandstatus["targetRevision"]!=status["currentRevision"]:results.append(doc)returnresultsscheduler=load("scheduler.yaml")cm=load("controller_manager.yaml")api=load("api_server.yaml")stale=get_stale([scheduler,cm,api])
或者你可以这样做：
fromsquerlyimportList,convert,Queryablescheduler=convert(load("scheduler.yaml"))cm=convert(load("controller_manager.yaml"))api=convert(load("api_server.yaml"))docs=Queryable(List([scheduler,cm,api]))stale=docs.status.nodeStatuses.where(lambdas:s.currentRevision!=s.targetRevision).roots
或者更好的方法是运行./analyze.py must-gather.local.12345/并访问
every存档中的资源：
In[1]:stale=conf.status.nodeStatuses.where(lambdas:s.currentRevision!=s.targetRevision).rootsIn[2]:stale.kindOut[2]:-kind:KubeScheduler-kind:KubeAPIServerIn[3]:conf.find(("message",matches("Perm")))Out[3]:-message:'rm: cannot remove ''/etc/cni/net.d/80-openshift-network.conf'': Permissiondenied'-message:'rm: cannot remove ''/etc/cni/net.d/80-openshift-network.conf'': Permissiondenied'-message:'+ source /run/etcd/environment/bin/sh:line3:/run/etcd/environment:Permissiondenied'In[8]:conf.find(("message",matches("Perm"))).upto("items").metadata.nameOut[8]:-name:sdn-7llq6-name:etcd-member-control-plane-0
