python - AttributeError：Python 代码中的 __getitem__

问题描述

我正在尝试打开一个名为filteredApps.txt 的文本文件，其中包含“app1.ear、app2.ear、app3.ear、app4.ear”作为新行，将其传递给一个列表，然后将其与另一个列表进行比较。然后最后在 main() 方法中调用部署函数，但我得到 AttributeError: getitem在代码下面突出显示的行中：

appNames = ['/opt/app1.ear', '/opt/app2.ear', '/opt/app3.ear', '/opt/app4.ear']

def filteredApps():
    filteredAppsList = []
    appToDeploy = open("filteredApps.txt","r")
    for deploy in appToDeploy:   #Code breaks here
        filteredAppsList.append(deploy)
    return map(str.strip, filteredAppsList)

def main():
    finalListToDeploy = []
    listToDeploy = filteredApps() #Code breaks here as well

    for paths in appNames:
        for apps in listToDeploy:
            if apps in paths:
                finalListToDeploy.append(apps)
    deployApplication(finalListToDeploy)

if __name__ == "__main__":
    main()

解决方案

继续评论：

过滤应用程序.txt：

app1
app2
app3
app4

因此：

appNames = ['/opt/app1.ear', '/opt/app2.ear', '/opt/app3.ear', '/opt/app4.ear']

def filteredApps():
    filteredAppsList = []
    with open("filteredApps.txt","r") as appToDeploy:
      for apptodeploy in appToDeploy:
          # print(apptodeploy)
          filteredAppsList.append(apptodeploy)
    return map(str.strip, filteredAppsList)

def main():
    finalListToDeploy = []
    listToDeploy = list(filteredApps())
    for paths in appNames:
        for apps in listToDeploy:
            if apps in paths:
                # print(paths)
                finalListToDeploy.append(paths)
    return finalListToDeploy
    # deployApplication(finalListToDeploy)

if __name__ == "__main__":
    print(main())

输出：

['/opt/app1.ear', '/opt/app2.ear', '/opt/app3.ear', '/opt/app4.ear']
