Instructor-led • live & hands-on

Begin Python. Crack the code.

Unlock the secrets of Python programming as you learn to break ciphers, unravel cryptic messages, and build real coding skills. Four weeks, zero prior experience needed, one confident codebreaker: you. Your first program starts with print("hello, world") and ends with cracking encryption you built yourself.

Instructor-led Python Course
Instructor-led

Learn Python live, not from a playlist.

This is an instructor-led course. You will learn live, whether onsite or online if you would rather join virtually. Ask questions, get real-time help, and interact with your trainer in a real class.

With small class sizes (max 25), you will not just sit and listen, you will actively code in Python, crack ciphers, and have fun with your instructor and classmates. No recorded videos, no skipping ahead, no pausing forever, just real, engaging learning.

Who can join this course? ↓
Who can join

No prior coding required. Just curiosity.

Crack Ciphers live, at the hackathon

Bring weeks 1 through 4 together to encrypt, decrypt, and hack Ciphers, then put it to the test against your classmates in The Great Cipher Showdown.

Build & break encryption

Four ciphers. One decoder ring of skills.

Through this course, you will dive into the exciting world of encryption and break open some of the most fascinating ciphers with Python, learning the secrets behind each one and how to decode them.

Hacking Reverse Cipher with Python

Reverse Cipher

Hides secrets in plain sight by simply flipping the message backwards, like reading code through a mirror. Your first taste of thinking like a codebreaker.

Hacking Caesar Cipher with Python

Caesar Cipher

Shifts the alphabet like a secret dance, where each letter steps a few spaces from its spot. Crack this classic and feel like a time-traveling detective.

Hacking Transposition Cipher with Python

Transposition Cipher

A master of disguise: it rearranges the letters of a message without changing them, turning order itself into secrecy.

Hacking Affine Cipher with Python

Affine Cipher

Takes encryption up a notch with multiplication and addition together, transforming letters through a mathematical formula into encoded brilliance.
