Day 8: Python Strings Adventure

1 Creating Strings 📝

💡 Learn: Strings are text in Python. You can use single quotes ' ' or double quotes " "!

Try this: Run the code and see different ways to create strings!

name = "Alice"
game = 'Minecraft'
sentence = "I love Python!"

print(name)
print(game)
print(sentence)

print('You can use "quotes" inside single quotes!')
print("Or use 'quotes' inside double quotes!")

🤔 Pro Tip: Both 'text' and "text" work the same! Use whichever you prefer.

2 Joining Strings (Concatenation) ➕

💡 Discovery: You can join strings together using the + symbol!

first_name = "Super"
last_name = "Hero"
full_name = first_name + last_name
print(full_name)

full_name_space = first_name + " " + last_name
print(full_name_space)

greeting = "Hello, " + "World" + "!"
print(greeting)

✨ Notice: Don't forget to add spaces! "Super" + "Hero" = "SuperHero", but "Super" + " " + "Hero" = "Super Hero"

3 String Magic Methods ✨

💡 Cool Tools: Strings have special powers called methods! Try these out!

.upper() - Makes everything UPPERCASE

"hello".upper() → "HELLO"

.lower() - makes everything lowercase

"HELLO".lower() → "hello"

.title() - Makes Every Word Start With Capital

"hello world".title() → "Hello World"

message = "hello world"
print(message.upper())
print(message.lower())
print(message.title())

name = "alice"
print("Welcome, " + name.upper() + "!")

shout = "this is awesome"
print(shout.upper() + "!!!")

4 String Slicing 🔪

💡 Cool Trick: You can grab parts of a string! Each letter has a position (starting at 0).

Example: In "HELLO", H is position 0, E is position 1, etc.

word = "PYTHON"
print(word[0])
print(word[1])
print(word[5])

print(word[0:3])
print(word[2:5])
print(word[:3])
print(word[3:])

name = "Alexander"
nickname = name[:4]
print(nickname)

🎯 Quick Guide:
• word[0] = first letter
• word[0:3] = letters 0, 1, 2 (not 3!)
• word[:3] = from start to position 3
• word[3:] = from position 3 to end

5 Quick Quiz! 🎯

🤔 Test Time: What will this code print? Click your answer!


                    text = "Hello"

                    print(text[1:4])

A) Hello

B) ell

C) Hel

D) ello

6 F-Strings (The Easy Way!) 🚀

💡 Super Power: F-strings make it super easy to put variables inside text! Just add f before the quotes and use {variable}.

name = "Alex"
age = 12
score = 95

print(f"My name is {name}")
print(f"I am {age} years old")
print(f"{name} scored {score} points!")

x = 10
y = 20
print(f"{x} + {y} = {x + y}")

game = "Minecraft"
hours = 100
print(f"I've played {game} for {hours} hours!")

✨ Why F-strings Rock: Instead of "Hello " + name, just write f"Hello {name}"! Much easier! 🎉

7 Final Project: Story Creator 📖

🚀 Big Challenge: Create a story using everything you learned! Run it and fill in your answers!

print("=== STORY CREATOR ===")
name = input("Character name: ")
place = input("A place: ")
thing = input("A thing: ")

story = f"""
Once upon a time, {name.title()} went to {place}.
There, they found a magical {thing.upper()}!
"{thing.title()}!" shouted {name.title()}.
And they lived happily ever after!
"""

print(story)

💪 Extra Challenge: Can you add more inputs to make the story longer? Try adding an action or an animal!
