Tech With Galvan

🧪 Practice: First Steps

Reading feels like knowing. Typing is knowing. This practice session locks in everything from Module 1 — no new concepts, just reps.

How it works: solve each exercise in your own file (practice1.py), run it, check your output. Solutions are at the bottom — attempt first, peek only after a real attempt.

Exercise 1 — The ritual

Print exactly this (with your own name):

code

Hello, World!
My name is ____
I am learning Python

Exercise 2 — Fix the broken code

This code has two errors. Find and fix them without rewriting from scratch:

code

prnt("Hello")
print('Done")

Exercise 3 — One print, three lines

Print this using only one print() statement:

code

Roses are red
Violets are blue
Python is fun

*(Hint: \n inside a string means "new line".)*

Exercise 4 — The math machine

Print the answers to: 5 + 3, 10 - 4, 6 * 7, and 20 / 4 — each on its own line, using print with the math *inside* the parentheses (no quotes around the math!).

Then answer: why do the first three print whole numbers but the fourth prints 5.0?

Exercise 5 — Break and read

Type this *exactly* (yes, it's broken):

code

print("Counting: 1, 2, 3)
print("Done!")

Run it. Read the error out loud, slowly. Fix only what the error complains about. Run again. If a new error appears, read that one too. Repeat until it works.

Solutions

Exercise 1:

code

print("Hello, World!")
print("My name is Galvan")
print("I am learning Python")

Exercise 2: prnt is misspelled (Python only knows print — a misspelled name gives NameError: name 'prnt' is not defined), and the second line mixes quote types: opens with ' and closes with ". Both must match.

code

print("Hello")
print('Done')

Exercise 3:

code

print("Roses are red\nViolets are blue\nPython is fun")

\n is the newline character — one string, three printed lines.

Exercise 4:

code

print(5 + 3)    # 8
print(10 - 4)   # 6
print(6 * 7)    # 42
print(20 / 4)   # 5.0

The / operator always produces a float (decimal) in Python 3, even when the result is whole: 5.0 not 5. If you want a whole number, use // (floor division): 20 // 4 gives 5.

Exercise 5: The first line is missing its closing quote, so Python reports SyntaxError: unterminated string literal. After fixing it, the program runs — both lines print.

✅ Checkpoint

All five solved from your own keyboard? Module 1 is complete. You can now:

Create and run a Python file

Read error messages instead of fearing them

Print anything, in any format

Next module is where Python starts getting *interesting*: the building blocks — keywords, identifiers, and the tokens that make up every line of code you'll ever write.
