Question

Additional Requirements

1.The name of your source code fileshould be ProbEst.py All your code should be within a single file.

2.You cannot import any package except for pandas.You need to use the pandas DataFrame object for storing data

Requirements Y ou are to create a program in Python that performs the following: 1. Asks the user for the number of cars (i.e. data instances) . 2. F or each car , ask s the user to enter the following fields: make, model , type (coupe, sedan, SUV), rating (A, B, C, D, or F) . Save the feature values for each car in a DataFrame object. 3. Display s the resulting DataFrame 4. Compute s the probability of each rating and output s to the screen. 5. For each type , compute s the conditional probability of that type, given each of the ratings: 6. Display s the conditional probabilities to the screen.

Output

70-511, [semester] [year]

PROGRAMMING ASSIGNMENT #4

Enter the number of car instances:6

Enter the make,model,type,rating:ford,mustang,coupe,A

Enter the make,model,type,rating:chevy,camaro,coupe,B

Enter the make,model,type,rating:ford,fiesta,sedan,C

Enter the make,model,type,rating:ford,focus,sedan,A

Enter the make,model,type,rating:ford,taurus,sedan,B

Enter the make,model,type,rating:toyota,camry,sedan,B

   make   model             type                 rating

0 ford             mustang         coupe                 A

1 chevy          camaro           coupe B

2 ford             fiesta              sedan                  C

3 ford             focus              sedan    A

4 ford             taurus            sedan                   B

5 toyota         camry sedan                  B

Prob(rating=A) = 0.333333

Prob(rating=B) = 0.500000

Prob(rating=C) = 0.166667

Prob(type=coupe|rating=A) = 0.500000

Prob(type=sedan|rating=A) = 0.500000

Prob(type=coupe|rating=B) = 0.333333

Prob(type=sedan|rating=B) = 0.666667

Prob(type=coupe|rating=C) = 0.000000

Prob(type=sedan|rating=C) = 1.000000
