Python Introduction

Python is a professional programming language. It is used by engineers in all sorts of applications.

Variables

Varibles hold values.

days = 7
hours = days * 24
minutes = hours * 60
print(minutes)

10080

Functions

Functions in a programming language like python can take in values and return a value. It is similar to a function in math

def emphasize(statement):
    refrase = statement.upper()
    refrase = refrase + "!"
    return refrase

print(emphasize("Hello"))

HELLO!

Loops

Loops, or iteration, allow us to have a computer to run code multiple times. It is a part of flow of control, generally tied to a condition. In the case of the example below, as long as the expression evaluates to true the loop keeps running. Once it is no longer true, the program will exit the loop.

def greet(times):
    i = 0
    while i < times:
        print("Hello!")
        i += 1

greet(5)

Hello!
Hello!
Hello!
Hello!
Hello!
