How to Find Values Within Lists in Dictionary Using Python

Do you have a collection of data in a dictionary format and need to extract specific values based on some criteria? If you're working with historical game scores, as in the case of the Oregon Ducks, you might find yourself facing a similar problem. In this guide, we will guide you through a straightforward method of retrieving and summing scores using a Python dictionary.

Understanding the Problem

You have a list of historical game scores stored in a certain format, where each entry contains a game date, season, opposing team, points scored by the Oregon Ducks, and points allowed by the Ducks. The goal here is to parse this list into a dictionary and then create a function to sum the scores for a specific season.

For example, if you run the parsing function on the data for the year 1916, you should be able to find:

The total scores the Ducks made

The total points allowed by the opposing teams

Solution Steps

Step 1: Parsing the Data

First, you need to convert the list of strings into a dictionary. This has already been accomplished with the following function:

This function takes a list of game records, extracts key information, and organizes it into a dictionary format. The result for the provided data yields the following dictionary:

Step 2: Summing Scores by Year

Next, you need to define a function that sums the scores for a specific year. This can be achieved with the following implementation:

How It Works

Initialization: The function initializes two variables scored and allowed to zero.

Iteration: It loops through each index and value in the season list of the dictionary.

Condition Check: If the season matches the input year, the function adds the corresponding scores from the scored and allowed lists to the totals.

Return Values: Finally, the function returns a tuple containing the total scores made by the Ducks and the total points allowed by the opposing teams for the specified year.

Example Usage

To utilize this function, apply it to the dictionary created from our data:

This output indicates that during the year 1916, the Oregon Ducks scored a total of 51 points and allowed 17 points from their opponents.

Conclusion

By breaking down the problem of extracting and summing scores from a dictionary, you can effectively manage and analyze sports data in Python. Using the provided functions, you can easily adapt the approach for different datasets and requirements. We hope this guide helps you with your data manipulation needs in programming.

Remember, practice makes perfect, so try implementing this with your own datasets to enhance your skills!
