### Objective

Write a python assignment program to calculate food density.

## Requirements and Specifications

Given a text file of data about fruit with three columns of data: mass (float), volume (float) and type (string, e.g., "apple" or “orange”). Read in the data and calculate the average density of the apples and oranges.

Source Code

```def read_data(filename): f = open(filename, 'r') data = [] lines = f.read().splitlines()[1:] for line in lines: parts = line.split(',') data.append([parts[0], float(parts[1]), float(parts[2])]) f.close() return data def main(): total_volume = {'apple': 0.0, 'orange': 0.0} total_mass = {'apple': 0.0, 'orange': 0.0} for rec in read_data('fruit.csv'): if rec[0] in total_mass: total_mass[rec[0]] += rec[1] total_volume[rec[0]] += rec[2] print('Apple density:', (total_mass['apple']/total_volume['apple'])) print('Orange density:', (total_mass['orange']/total_volume['orange'])) if __name__ == '__main__': main() ```
