📝 🎉 Welcome to Variable Wonderland!

Brace yourselves! We’re diving into Python’s world of variables and objects. 🐍

🧪 What are Variables?

Think of variables as the digital Post-it Notes of programming. Stick whatever you want on them—numbers, text, or your hopes and dreams (just kidding, maybe).

x = 5
y = 'Drexel'
print(f'Behold x: {x} and y: {y}')

Behold x: 5 and y: Drexel

🤯 Guess What? No Declarations!

Unlike some languages that nag you to declare everything (cough C++), Python is cool. Assign a value, and voilà! The variable exists.

z = 42.0
print(type(z))  # Python knows it's a float!

<class 'float'>

🎭 Strings Are Drama Queens

Wrap them in single (') or double (") quotes. Python doesn’t judge, but keep it consistent!

name1 = 'Engineer'
name2 = "Extraordinaire"
print(f'Hello, {name1} {name2}!')

Hello, Engineer Extraordinaire!

😜 Python is Case-Sensitive

x and X are NOT the same. Engineers, don’t lose your variables to uppercase confusion!

x = 5
X = 10
print(f'Lowercase x: {x}, Uppercase X: {X}')

Lowercase x: 5, Uppercase X: 10

🕺 Dance of Variable Names

• Variable names must waltz to these rules:

  • Start with a letter or underscore.

  • Can’t start with a number (Python hates leading digits).

  • Alpha-numeric and underscores only—no emojis! 😢

• And yes, they are case-sensitive (again, watch out!).

🤹‍♀️ Juggling Variables

Python loves efficiency. Assign multiple variables in one go:

a, b, c = 1, 'fun', 3.14
print(f'Values: a={a}, b={b}, c={c}')

Values: a=1, b=fun, c=3.14

🌟 Objects Are Everything

Python treats variables like celebrities—everything is an object with special powers (methods).

s = 'Engineering Rules!'
print(s.upper())  # SHOUT IT!

ENGINEERING RULES!

f = 100.0
print(f.is_integer())  # Is this an integer, really?

True
