Overview of Python Virtual Environments

This guide is targetted at intermediate or expert users who want low-level control over their Python environments.

When you're working on multiple coding projects, you might want a couple different version of Python and/or modules installed. This helps keep each workflow in its own sandbox instead of trying to juggle multiple projects (each with different dependencies) on your system's version of Python. The guide here covers one way to handle multiple Python versions and Python environments on your own (i.e., without a package manager like conda). See the Using the workflow section to view the end result.

A Typical directory structure for running tests using unittest

Ref : stackoverflow

The best solution in my opinion is to use the unittest [command line interface][1] which will add the directory to the sys.path so you don't have to (done in the TestLoader class).

For example for a directory structure like this:

new_project

├── antigravity.py

class Api::V1::ProfitAndLossController < ApplicationController
  def index
    render json: Sale.get_profit_and_loss, each_serializer: ProfitAndLossSerializer
  end
end

class Client < ApplicationRecord
  ...

  def self.get_top_customers
    month = Sale.get_latest_month
    Client.find_by_sql [
      "WITH top_cust AS (
      SELECT SUM(sales.amount) AS sales_17, 
             SUM(discounts.amount) AS discounts_17, 
             SUM(sales.amount) + SUM(discounts.amount) AS net_sales_17,

class DashboardSerializer < ActiveModel::Serializer
  attributes :clusters, 
             :products, 
             :categories, 
             :net_sales_curr_year, 
             :segment_contribution, 
             :net_sales_prev_year, 
             :discounts_17

  def net_sales_prev_year
