Sweep: I need you to optimize the code in 'Brokers/BrokerUtils/broker_tax_calc.py'

[omkarh25]

Details

there is lot of redundant variables and hard coded values in the code. Remove coupling in the code by extracting constants and hard coded values. Use this documentation: https://zerodha.com/charges#tab-equities, for exact value reference from equity segment

Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Some code snippets I think are relevant in decreasing order of relevance (click to expand). If some file is missing from here, you can mention the path in the ticket description.

I also found the following external resources that might be helpful:

**Summaries of links found in the content:** https://zerodha.com/charges#tab-equities: The page titled "List of all fees, charges, and taxes on trading and investing" on the Zerodha website provides information about the fees, charges, and taxes associated with trading and investing. The page includes a detailed breakdown of charges for different types of trades, such as equity delivery, equity intraday, futures and options, currency, and commodity. It also mentions the various taxes and charges levied by the government, such as Securities/Commodities transaction tax, GST, SEBI charges, stamp charges, and more. The page further provides information about additional charges for services like call & trade, NRI brokerage charges, account opening charges, value-added services, and other miscellaneous charges. The user is specifically looking to extract constants and hard-coded values from the code and remove coupling. The page also includes a disclaimer and information about Zerodha's registration and contact details.

Step 2: ⌨️ Coding

• [X] Create Brokers/BrokerUtils/constants.py ✓ https://github.com/SerendipityOrg/TradeMan/commit/e2b940774976d40efe4c18a63872db48f4271dd6 Edit

  Create Brokers/BrokerUtils/constants.py with contents:
  • Create a new file named 'constants.py' in the 'Brokers/BrokerUtils/' directory.
  • Define constants for all the hard-coded values currently in the 'broker_tax_calc.py' file. The constants should be named in a way that clearly indicates what they represent. For example, 'BROKERAGE_ZERODHA' for the brokerage charge for Zerodha, 'STT_CTT_RATE' for the STT/CTT rate, etc.
  • The values for the constants should be taken from the link to the Zerodha website provided by the user. Double-check the values to ensure they are accurate.

  Modify Brokers/BrokerUtils/broker_tax_calc.py with contents:
  • Import the constants defined in 'constants.py' at the beginning of the 'broker_tax_calc.py' file.
  • Replace all the hard-coded values in the 'broker_tax_calc.py' file with the corresponding constants. For example, replace the hard-coded value of 20 for the brokerage charge for Zerodha with 'BROKERAGE_ZERODHA', the hard-coded value of 0.0125 / 100 for the STT/CTT rate with 'STT_CTT_RATE', etc.
  • Ensure that all the hard-coded values have been replaced with the corresponding constants.

🎉 Latest improvements to Sweep:

• We just released a dashboard to track Sweep's progress on your issue in real-time, showing every stage of the process – from search to planning and coding.
• Sweep uses OpenAI's latest Assistant API to plan code changes and modify code! This is 3x faster and significantly more reliable as it allows Sweep to edit code and validate the changes in tight iterations, the same way as a human would.
