Walkthrough

The changes introduce a lottery simulation in Python that draws lottery numbers, calculates winnings based on user-defined tickets, and tracks winning combinations. A new file, lottery.py, implements the simulation logic, including a function to compute winnings and update a dictionary of winning statistics. Additionally, a new file, snippets.txt, outlines the mechanism for tracking the frequency of winning scenarios.

Python/Python-Lottery-Simulation/lottery.py Introduced a lottery simulation that calculates potential winnings, tracks spending, and maintains winning statistics based on user-defined tickets.
Python/Python-Lottery-Simulation/snippets.txt Added a mechanism to track winning combinations, initializing a dictionary to count occurrences of different winning scenarios based on defined rules.

Poem

🐰 In a world of numbers, bright and fair,
A lottery dance, with excitement in the air!
Tickets in hand, we play our chance,
Hoping for winnings in a joyful glance.
With each draw, our dreams take flight,
Let the numbers twirl, oh what a delight! 🌟

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

1-12: LGTM!

The dictionary times_won is correctly initialized to track the frequency of different lottery outcomes.

The code changes are approved.


16-40: Fix indentation issue.

The elif statement on line 16 should be aligned with the previous if statement to ensure correct execution flow.

Apply this diff to fix the indentation issue:

-elif white_matches == 4:
+    elif white_matches == 4:

Likely invalid or redundant comment.

1-24: LGTM!

The imports and initializations are correctly set up for the lottery simulation.

The code changes are approved.


102-105: LGTM!

The print statements correctly output the relevant information at the end of the simulation.

The code changes are approved.

Refactor to avoid duplication.

The logic for updating the times_won dictionary is duplicated from snippets.txt. Consider extracting this logic into a separate function to avoid duplication and improve maintainability.

Apply this diff to extract the dictionary update logic into a separate function:

+def update_times_won(white_matches, power_match):
+    if white_matches == 5:
+        if power_match:
+            times_won["5+P"] += 1
+        else:
+            times_won["5"] += 1
+    elif white_matches == 4:
+        if power_match:
+            times_won["4+P"] += 1
+        else:
+            times_won["4"] += 1
+    elif white_matches == 3:
+        if power_match:
+            times_won["3+P"] += 1
+        else:
+            times_won["3"] += 1

Rename unused loop control variable.

The loop control variable ticket is not used within the loop body. Consider renaming it to _ticket to indicate that it is unused.

Apply this diff to rename the unused loop control variable:

 for _ticket in range(tickets_per_drawing):
     total_spent += 2
     my_whites = set(random.sample(white_possibles, k=5))
     my_red = random.choice(red_possibles)

     my_numbers = {"whites": my_whites, "red": my_red}

     win_amt = calc_win_amt(my_numbers, winning_numbers)
     earnings += win_amt

     if win_amt == 2_000_000_000:
         hit_jp = True
         break
