Use NumPy & Pandas smartly

Context: Loops in Python are slow for data manipulation. NumPy and Pandas provide vectorized operations that are significantly faster.
Example: Instead of looping through an array, use NumPy’s built-in functions:
python
import numpy as np
arr = np.array([1, 2, 3, 4, 5])
arr_squared = np.square(arr) # Vectorized operation (fast)
👉 Faster than:
python
arr_squared = [x**2 for x in arr] # Slower loop-based approach

 Preprocess your data!

Context:Handling missing values is crucial before feeding data into an ML model.
Example:Using SimpleImputer to fill missing values:
python
from sklearn.impute import SimpleImputer
import pandas as pd
df = pd.DataFrame({'A': [1, 2, None, 4]})
imputer = SimpleImputer(strategy='mean')
df['A'] = imputer.fit_transform(df[['A']])

 Automate early, automate often!

Context: Writing tests early prevents bugs from accumulating in the codebase
Example:
python
def add(a, b):
  return a + b
def test_add():
  assert add(2, 3) == 5

 Use mocks effectively

Context:Simulate dependencies in unit tests using unittest.mock.
Example:
python
from unittest.mock import MagicMock
db_mock = MagicMock()
db_mock.get_data.return_value = {"id": 1, "name": "John"}
assert db_mock.get_data()["name"] == "John"

 Use Async/Await properly

Context: Avoid blocking threads in async methods.
Example:
csharp
public async Task GetDataAsync() {
  return await httpClient.GetStringAsync("https://example.com");
}

 Entity Framework Best Practice

Context:Use AsNoTracking() for read-only queries to improve performance.
Example:
csharp
var users = dbContext.Users.AsNoTracking().ToList();
