Managing files with Python

• We have written a simple student details store Refer Here
• This application stores the values in a dictionary and fetches them
• Problem with this approach is storage is temporary (exists as long as application runs)
• To store the student details we need to store the data to external storage which is considered as persistence
• Options:
  • file
  • database
• Lets consider file as a option for now.
• Which format?
  • text
    • txt
    • csv
    • json
    • yaml
    • xlsx
    • …
  • binary
• We have implemented the json file storage and retrieval Refer Here
