Career Path

Code like a Data Analyst

Stop copy-pasting code you don't understand. Build the fundamental fluency in Python and SQL required to automate your workflow and uncover deeper insights.

Python for Data

Master the syntax behind data manipulation libraries. Learn loops, list comprehensions, and functions to clean and process data at scale.

SQL for Retrieval

The most important tool in a data analyst's kit. Practice joins, aggregations, and subqueries until you can query any database with confidence.

Why interactive practice beats
watching tutorials.

Precision over Guesswork

Fill-in-the-blank forces you to know the exact syntax. No more "I think this works" – you'll know it does.

Workflow Automation

Once the syntax is in your muscle memory, you'll stop searching Google for basic loops and start building complex automation.

Analyst Code Snippet

# Calculate percentage change
def calc_growth(data):
  return [
    (curr - prev) / prev 
    for prev, curr in zip(
      data[:-1], data[1:]
    )
  ]

"Mastering this pattern saves 2 hours of manual Excel work every week."
