Py & Jamthe daily email method with a …
coding habit 🐍
One real function. The kind you'll actually use.
Free, every morning.
One real function a week, taught through free daily emails where the code fades a line at a time until you can write it from memory 🧠.
Join readers starting every morning with us.
Each day, more of the code disappears.
Day 1
Day 3
Stuck on a line?
You can always read the full function and a plain-English breakdown of every line in each email.
Research shows this pairing - recall plus understanding - is what makes each week's function stick for good.
Your first morning email is one click away. Free, no card.
Each day, more of the code disappears, training your brain to recall it from memory.
This is how it sticks.
Day 1: The full function
"def check_password(password): if len(password) < 8: return "Weak" has_number = False for char in password: if char.isdigit(): has_number = True if has_number: return "Strong" return "Medium""
"The whole function, start to finish. Under 8 characters? It answers "Weak" right away. Otherwise it walks through the password looking for a digit - found one, it's "Strong"; none, it's "Medium". Read it, run it, get a feel for the shape."

Day 2: The first lines fade
"def check_password(password): ____ ____ has_number = False for char in password: if char.isdigit(): has_number = True if has_number: return "Strong" return "Medium""
"Today's lines: the length check. if len(password) < 8 asks one question before anything else - too short? Then return "Weak" ends the function right there. Everything below only runs for passwords that pass."

Day 3: More lines to fill
"def check_password(password): ____ ____ has_number = False for char in password: ____ ____ if has_number: return "Strong" return "Medium""
"Today's lines: the loop body. if char.isdigit() checks each character in turn, and has_number = True flips the flag the moment a digit shows up. The for line stays put - it's part of your skeleton."

Day 4: Test your memory
"def check_password(password): ____ ____ ____ for char in password: ____ ____ if has_number: ____ return "Medium""
"Most of the body is gone now. Only the skeleton holds the shape: the def line, the for loop, if has_number, and the final return "Medium". Can you say out loud what belongs on each blank line?"

Day 5: Write it from memory
"def check_password(password): ____ ____ ____ for char in password: ____ ____ ____ ____ return "Medium""
"From memory now: write the body back into the skeleton. Answer key: the length check returns "Weak" early, the loop hunts for a digit, "Strong" if it finds one, "Medium" if it doesn't. Paste your version into Ada and watch it run."

It's not you. It's how code is usually taught.

You code along, it runs, you feel great. A week later you open a blank file and can't write it without the video.

Stack Overflow gets it working today, but none of it lands in your head - so tomorrow you're searching the same thing again.
