Appending to dictionary in text file in Python inside the brackers {}

Question

I am trying to append a message along with a name to an empty dictionary in a text file.

def tweeting():
    f = open('bericht.txt', 'a')
    message = input('Put in message:  ')
    name = input('Put in your name: ')
    if name == '':
        name = 'Anonymous'
    tweet = name + '; ' + message
    f.write(tweet)
    f.close()
tweeting()

The result I am getting is this:

Tweets = {

}David; Hello everyone

The message goes after the brackets {}. Is there a way to put the message inside the brackets {} ? Thanks for the help.

Answer 1

Try the following. Just take care of the quotes in name and message, if you want the text in your file to be as a dictionary. If they are not typed by user, they must be added to t before t is written in the file:

def tweeting():
    with open('bericht.txt') as f:
        t=f.read()
    if ':' in t:  #that means that t has other elements already
        t=t[:-1]+','
    else:
        t=t[:-1]
    message = input('Put in message:  ')
    name = input('Put in your name: ')
    if name == '':
        name = 'Anonymous'
    t += name + '; ' + message + '}'
    with open('bericht.txt', 'w') as f:
        f.write(t)
