AttributeError: getitem in Python code

Question

I'm trying to open a text file called filteredApps.txt which contains "app1.ear, app2.ear, app3.ear, app4.ear" as new lines, pass it to a list and then compare it to another list. Then finally call the deploy function in the main() method but I get AttributeError: getitem in the line hightlighted below on the code:

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()

appToDeploy = open("filteredApps.txt","r") not the right way to do it — DirtyBit

I'm just highlighting which lines jenkins says the error comes from. The code breaks before the deployApplication() is called so it is not relevant for this question — Sizwe

Continuing from the comments:

filteredApps.txt:

app1
app2
app3
app4

Hence:

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())

OUTPUT:

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

Try to use open as follow:

import io
from io import open
with open('tfilteredApps.txt', 'r', encoding='utf-8') as file :    
    for deploy in file :
        filteredAppsList.append(deploy)

But if you have all app name in one line it gonna be like this with pickle module:

import pickle
with open('tfilteredApps.txt', 'r', encoding='utf-8') as file :
    word = pickle.load(file)
filteredAppsList = word.split(' ')

Try reading the file before looping over the data

 appToDeploy = open("filteredApps.txt","r") 
 contents = appToDeploy.readlines()
 appToDeploy.close()

 for deploy in contents:     
     filteredAppsList.append(deploy)

@Sizwe that's got something to do with your map(str.strip, filteredAppsList)
