print("Labels:", labels) # Output: ['Low' 'Low' 'High' 'High' 'High']

When working with databases using Python (via libraries like sqlite3 , SQLAlchemy , or psycopg2 ), you will write raw SQL queries containing the WHERE clause inside Python strings.

connection.close()

Happy learning!

| Context | Tool | Syntax Example | What it does | | :--- | :--- | :--- | :--- | | | sqlite3 / sqlalchemy | SELECT * FROM table WHERE x = 1 | Filters rows in a database query. | | Pandas | Boolean Indexing | df[df['col'] > 5] | Returns only rows that match the condition (Standard usage). | | Pandas | .where() | df.where(df > 5) | Keeps all rows, replaces non-matching values with NaN . | | NumPy | np.where() | np.where(arr > 5) | Returns the indices of matching elements. | | NumPy | np.where() | np.where(arr > 5, 'A', 'B') | Returns 'A' if condition met, otherwise 'B'. | where python

The fastest way to find where Python is currently running is by using the command line:

If you've ever asked "Where does Python actually go?" — the real answer is: almost everywhere. | | Pandas | Boolean Indexing | df[df['col']

arr = np.array([10, 20, 30, 40, 50])
