[英]AttributeError: __getitem__ in Python code
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. 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,将其传递到列表中,然后将其与另一个列表进行比较。 Then finally call the deploy function in the main() method but I get AttributeError: getitem in the line hightlighted below on the code:
然后,最后在main()方法中调用deploy函数,但是在下面代码中突出显示的行中,我得到AttributeError: getitem :
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()
Continuing from the comments: 从评论继续:
filteredApps.txt: filteredApps.txt:
app1
app2
app3
app4
Hence : 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())
OUTPUT : 输出 :
['/opt/app1.ear', '/opt/app2.ear', '/opt/app3.ear', '/opt/app4.ear']
Try reading the file before looping over the data 在遍历数据之前尝试读取文件
appToDeploy = open("filteredApps.txt","r")
contents = appToDeploy.readlines()
appToDeploy.close()
for deploy in contents:
filteredAppsList.append(deploy)
Try to use open as follow: 尝试按以下方式使用open:
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: 但是,如果您在一行中拥有所有应用程序名称,则使用pickle模块会像这样:
import pickle
with open('tfilteredApps.txt', 'r', encoding='utf-8') as file :
word = pickle.load(file)
filteredAppsList = word.split(' ')
