How to append to a file (in the same dict after restarting the server), using python socket programming

Here's the code I wrote for a server, which requests user info and stores them into a file:

# Function : For each client   def threaded_client(connection):      ''' codes that request and receive user massage... '''      # write the info into credentials.txt:      with open('credentials.txt', 'a') as f:          print(credentials, file = f)  

Ideally, when I exit the server and restart it, all the old and new info should be kept in the same dict.

Expected output:

{'username_1': 'his password', 'username_2': 'her password', 'a': 'b'}  

Actual output:

{'username_1': 'his password'}  {'username_2': 'her password', 'a': 'b'}  

What could be the issue here?
