Study Guide Module 1

✅ Knowledge Review

🐍 Benefits of Python

• Easy to read and write
• Used in web dev, data science, automation, AI, etc.
• Large community and many libraries

🆚 Python vs Other Languages

• Simpler syntax than Java/C++
• Interpreted (runs line by line)
• Great for beginners

🌐 How Knowing One Language Helps

• Programming logic is similar across languages (loops, functions, variables)
• Once you understand the basics, it’s easier to learn others (e.g., JavaScript, Java)

⚙️ What is Scripting?

• Writing code to automate tasks (e.g., rename files, process data)

✅ Terms to Know

Term	Definition
Computer program	A set of instructions to perform a task
Programming language	Language used to write code (e.g., Python)
Syntax	Rules for how code must be written

✅ Coding Skills to Practice

🧵 Skill 1: Use print()

print("I love Python!")
print(360)
print(32 * 45)

# With variables
x = 10
print(x)

🧮 Skill 2: Arithmetic Operators

print(3 * 8 / 2 + 5 - 1)

# Exponents
print(4 ** 6)  # 4 to the 6th power
print(4 ** 2)  # Square
print(4 ** 3)  # Cube
print(4 ** 0.5)  # Square root

🧠 Skill 3: Variables and Arithmetic

years = 10
weeks_in_a_year = 52
weeks_in_a_decade = years * weeks_in_a_year
print(weeks_in_a_decade)

❗ Reminder: Syntax Is Everything

Even one tiny mistake causes an error. Check for:

• 📝 Misspelled words
• 🔠 Wrong case (e.g., Print vs print)
• ❌ Missing colons (:)
• 👎 Unmatched parentheses (), brackets [], or braces {}
• 🔤 Wrong quotes (mixing “ ” instead of " ")

🧪 Example Errors and Fixes

Mistake	Correction
print("Hello'	print("Hello")
Print("hi")	print("hi")
x = 3 y = 4	x = 3; y = 4 or put each on a new line
print(2 **)	print(2 ** 3)
