Assignment – 3(part-A) Python Given a file rules

Assignment – 3(part-A) Python

Given a file rules.json with rules written in the following format:

    "fields": {

      "profession": "IT",

      "travel": "Yes",

      "symptomatic": "Yes"     },

    "results": "High Risk"

  },

  {

    "fields": {

      "profession": "Police",

      "travel": "No",

      "symptomatic": "No"

    },

    "results": "Moderate Risk"

  },

  {

    "fields": {

      "profession": "Police",

      "travel": "Yes",

      "symptomatic": "No"

    },

    "results": "High Risk"

  },

  {

    "fields": {

      "profession": "Police",

      "travel": "Yes",

      "symptomatic": "Yes"

    },

    "results": "High Risk"

  }

]

And a file data.csv that contains multiple records in the following format (Email, Profession, Travel, Symptomatic, Chronic):

Based on the rules and the incoming data from data file, create a new file results.csv in the following schema:

Result is derived based on the values of the fields mentioned in the rules.

Instructions

1. rules.json is a static JSON file.  That means for the submitted code, file content will not change. Rule list is exhaustive. Incoming data in data.csv will always have combination found in Rule JSON File
2. File format for Data file and New file with Result tag will be Comma Separated.
3. Ensure you lookup the rules file, match the incoming record data with right tag(as per the rules) and then insert the data into results.csv . For example

data.csv has three columns (Profession, Travel, Symptomatic). Rules Tag is derived from these three keys from rules.json file. Once you get the tag, insert the Data record along with new Result column in results.csv file.

4. HINTS: 
   1. You can create separate logic for deriving rules from JSON file and do look up on the rules when inserting data.
   2. You are free to generate any intermediary files. 
   3. You are free to use any python libraries. (supplied with standard python installation) 

Grading Criteria:

1. 1. Able to read from RULES JSON file and write appropriate tag into Results file.

(20)

1. 2. Submit a Flow chart for code logic (10)
   3. Accuracy of Result tag is 100%. Evaluators will test the code on a different Data file to evaluate the accuracy of Result’s column. Students are required to create their own data file, however schema of data file should be unchanged (25)
   4. Code is properly commented. Comments are inputted #.  (5)
   5. Rule logic to derive Tags from RULES JSON (25). 

If you use only If and else to derive logic – 12.5 marks

OR If you use Dictionary along with if and else – 25 marks

Else 0

1. 6. Moodle submission format (5):

<roll-number>.zip

------- lookup.py

------- rules.py  (Code to derive Rules from JSON File)

------- results.csv  (Code to lookup on the rules and insert into Result’s file) ------- flow_chart (png/jpeg/jpg)

Note:

It is recommended that the code is flexible to accommodate change in specs in the future assignments. This is however not a criterion for grading.
