如何获取文本文件并将其转换为python中的字典

Question

So what I am trying to do is load up all my usernames and passwords from a textfile into a dictionary to call upon them...

     def createacc():
                x = 0
                while x != 200:
                    print("\n")
                    x+=1
                answer = {}
                error = None
                with open('usernames.dat', 'r') as document:
                    for line in document:


                        n = line.replace("\n'","")

                        arts = n.replace("[","")

                        parts = arts.replace("['","")

                        nparts = parts.split("=")

                        line = parts


                        if not line:  # empty line?
                            continue
                        answer[line[0]] = line[1:]
                print("\n\n\n\n\n")
                print(answer)
                print("\n\n\n\n\n")


                if request.method == "POST":
                    if request.form['username'] == '' or request.form['password'] == "" or request.form['code'] != "30286":
                        error="Faliure to create account!! please try again"
                    else:
                        acc = open("usernames.dat","a+")

                        a = acc.readlines()
                        aaa = request.form['username'] +"="+ request.form['password'] + "\n"
                        acc.writelines(aaa)
                        acc.close()
                        return redirect(url_for('sms'))
                return render_template('newacc.html',error=error)

And What I was hoping my dictionary out would look like would be like so

{'admin':'admin', 'PPGC': 'Default', 'DELTA': 'Readme'}

and the result I am getting is

{'a': 'dmin=admin\\n', 'P': 'PGC\\n', 'D': 'ELTA\\n', 'N': 'AVI\\n'}

What do I need to do to get my desired dictionary?

Answer 1

Is your program writing the username, passwords in a textfile? If yes, I would suggest to use JSON or any other data interchange format. For example, with json you can do this

import json

user_dict = {'some user': 'some password'}

with open('my_database.json', 'w') as db:
    json.dump(user_dict, db)

# Now the data can be can easily loaded
user_data = json.load(open('my_database.json'))

# This will get you the dictionary back.
