Transforming Dictionary Keys with Incremental Numbering in Python

In the world of programming, managing data effectively is vital, especially when dealing with dictionaries in Python. One interesting problem arises when you need to create dictionary keys that depend on the frequency of values occurring within them.

In this guide, we'll share how you can achieve this using a specific example. Our goal is to modify a dictionary such that if a specific value is found multiple times, additional keys are generated with incremental numbering. Let’s dive into solving this problem step-by-step!

Problem Breakdown

Suppose you have a dictionary named TT holding specific types as keys, and each key maps to a list containing different values. Here's the dictionary we are working with:

We will also consider the following list of input strings:

The challenge here is that the value "TIME_OUT" appears twice in the input strings. Our aim is to dynamically create a new key in the dictionary whenever a value appears more than once.

Expected Output

After processing the inputs, we want to achieve the following dictionary structure:

Step-by-Step Solution

To implement this solution, we’ll leverage a counting mechanism to track how many times a value appears in the input sentences. Below is the code that accomplishes this:

Explanation of the Code

Inputs Declaration: We first declare our inputs and the dictionary containing the basic types.

Counting Mechanism: We define two dictionaries, type_counts to keep track of the occurrences of each value and results to store the final dictionary format.

Iterating through sentences: For each sentence, we check if any of our dictionary values are present. If found, we count the occurrences.

Dynamic Key Creation: If it's the first occurrence of a certain type, we simply add it to the results. Otherwise, we create a new key with incremental numbering based on how many times it has been found before.

Output: After processing, we print the newly formatted results!

Conclusion

With this approach, you can efficiently manage situations when values occur multiple times within a dataset, dynamically adjusting your dictionary keys as needed. Python provides us with the flexibility to implement such changes seamlessly, making it a versatile choice for data manipulation.

Feel free to take this concept and adapt it to your own projects, ensuring more robust and organized data handling in your applications!
