Master one function

every week in a 5-day email sequence.

Each day, more of the code disappears.

Day 1

1def check_password(password):
2    if len(password) < 8:
3        return "Weak"
4    has_number = False
5    for char in password:
6        if char.isdigit():
7            has_number = True
8    if has_number:
9        return "Strong"
10    return "Medium"

→

Day 3

1def check_password(password):
2    ____
3        ____
4    has_number = False
5    for char in password:
6        ____
7            ____
8    if has_number:
9        return "Strong"
10    return "Medium"

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.

// active recall

The magic of active recall.

Each day, more of the code disappears, training your brain to recall it from memory.

This is how it sticks.

check_password.pyDay 1

# The full function

1def check_password(password):
2    if len(password) < 8:
3        return "Weak"
4    has_number = False
5    for char in password:
6        if char.isdigit():
7            has_number = True
8    if has_number:
9        return "Strong"
10    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.

check_password.pyDay 2

# The first lines fade

1def check_password(password):
2    ____
3        ____
4    has_number = False
5    for char in password:
6        if char.isdigit():
7            has_number = True
8    if has_number:
9        return "Strong"
10    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.

check_password.pyDay 3

# More lines to fill

1def check_password(password):
2    ____
3        ____
4    has_number = False
5    for char in password:
6        ____
7            ____
8    if has_number:
9        return "Strong"
10    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.

check_password.pyDay 4

# Test your memory

1def check_password(password):
2    ____
3        ____
4    ____
5    for char in password:
6        ____
7            ____
8    if has_number:
9        ____
10    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?

check_password.pyDay 5

# Write it from memory

1def check_password(password):
2    ____
3        ____
4    ____
5    for char in password:
6        ____
7            ____
8    ____
9        ____
10    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.

This method of spaced repetition and line-by-line understanding moves you beyond copy-paste to code you can actually write.

// why it sticks

The Science Behind Our Method

Our approach is rooted in the latest research on memory and learning.

🧠

Spaced Repetition

Review material at optimal intervals to solidify it in your long-term memory.

📚

Contextual Learning

Learn each function in context to improve comprehension and retention.

🗣️

Active Recall

Engage with the material through active recall to strengthen your neural connections.

Meet Ada.

Ada. She runs your code.

Every day, you paste your version of the week's function andAda runs it - so you see it work, or see exactly where it breaks. Right in your browser, no setup, no app to download.

Free, right from your very first email.

you pasted

1def check_password(pw):
2    if len(pw) < 8:
3        return "Weak"
4    for char in pw:
5        if char.isdigit()
6            return "Strong"
7    return "Medium"

Ada ran it · traceback

File "solution.py", line 5

if char.isdigit()

SyntaxError: expected ':'

Line 5 is missing the colon after isdigit(). Add a : and your loop runs — nice work on the length check. 🐍

The emails put each function in your head.

Ada makes sure it runs.

Years of tutorials. Still Googling how to write a loop.

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

📚

Tutorials you follow but can't repeat

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

😫

Copy-paste that never sticks

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

🏳️

Courses that pile up, unfinished

Another 40-hour course, another 12% finished. Big commitments are easy to start and easy to abandon.

There's a better way.

Py & Jam delivers a 5-day email sequence to your inbox every week. One function at a time, until it stays with you.

Frequently Asked Questions

How long does it take to learn Python?

With consistent daily practice, most people can read and write small, useful Python programs within a few months. The trick isn't marathon study sessions - it's short, regular reps. Py & Jam gives you exactly that: one real function a week, five unhurried minutes a morning, sequenced so each week builds on the last.

What's the best way to learn Python for beginners?

The best approach combines real code, active recall, and running what you write - not passively watching tutorials. Start with one small function, understand every line, then rebuild it from memory. Py & Jam delivers this in 5-minute daily emails where the code fades a line at a time, and Ada runs your version so you know it works.

Can I learn Python in 5 minutes a day?

Yes - consistency beats intensity. Short daily sessions build stronger memory than sporadic hour-long blocks. Five focused minutes a day is enough to internalize one real function each week. Over a year that's 52 functions you can write from memory. Py & Jam is designed for exactly this.

How often will I get emails?

You'll get a new email every morning, Monday through Friday. Each week is one function, taught over a 5-day disappearing-code sequence - day 1 shows the full function, and each day more of it fades so your memory does the work.

Is Py & Jam free?

Yes - the daily emails are free. Sign up with just your email - no card required - and your first morning function arrives tomorrow. Unsubscribe any time in one click.

What makes this different from courses and tutorials?

Courses and videos are easy to follow and easy to forget - you code along, it works, and a week later you can't write it without the video. Py & Jam is built around what actually sticks: one small function at a time, plain-English explanations of every line, disappearing code that forces active recall, and Ada to run what you write. It comes to your inbox - no app, no streaks to protect.

Do I need to know how to code to start?

No. Week 1 is a short, real function, and every email explains it line by line in plain English. Complete beginners follow along from day one - and if you've dabbled before, this is how it finally sticks.

What if I miss a day?

No problem. Each email builds on the last but is designed to stand alone. Jump back in any time - missing a day won't derail your progress.

What is Ada?

Ada is your AI companion - paste your version of this week's function and Ada runs it, so you see it work (and see exactly where it breaks if it doesn't). Ada lives in your browser. No setup, no app to download.

Can I see past emails?

Yes! Browse the growing archive of every function we've sent. Preview the email archive here.
