Kaggle Challenge 02 - Hello Python

1. What are the differences Python to otheres

Aside: If you've programmed in certain other languages (like Java or C++), you might be noticing some things Python doesn't require us to do here:

we don't need to "declare" spam_amount before assigning to it
we don't need to tell Python what type of value spam_amount is going > to refer to. In fact, we can even go on to reassign spam_amount to > refer to a different sort of thing like a string or a boolean.

2. normal syntax

spam_amount = 0
print(spam_amount)

# Ordering Spam, egg, Spam, Spam, bacon and Spam (4 more servings of Spam)
spam_amount = spam_amount + 4

if spam_amount > 0:
    print("But I don't want ANY spam!")

viking_song = "Spam " * spam_amount
print(viking_song)

3. Operators

Operator	Name	Description
a + b	Addition	Sum of a and b
a - b	Subtraction	Difference of a and b
a * b	Multiplication	Product of a and b
a / b	True division	Quotient of a and b
a//b	Floor division	Quotient of a and b, removing fractional parts
a % b	Modulus	Integer remainder after division of a by b
a ** b	Exponentiation	a raised to the power of b
-a	Negation	The negative of a

One interesting observation here is that, whereas your calculator probably just has one button for division, Python can do two kinds. "True division" is basically what your calculator does:

4. Functions

Min and Max

They return the mimimum and maximum of their arguments.

print(min(1, 2, 3))
print(max(1, 2, 3))

<Result>
