Why Python?

  • Can be learned in a holiday

  • Perfect for assignments 

    • AI class

    • CS Games

  • Multi-purpose

Xkcd

import os

os.system('"sudo make_sandwich"')

What is Python?

  • Interpreted

  • Dynamic

  • Cake and cherry on the cake

name = "Michael"  #Most used male name in Canada in 1990
print "\n".join(map(lambda x: "Happy Birthday to " 
                      + ("you" if x != 2 else name),range(4)))

IPython

Live coding

Exercises

FizzBuzz

Write a program that prints the numbers from 1 to 100. But for multiples of 3 print “Fizz” instead of the number and for the multiples of 5 print “Buzz”. For numbers which are multiples of both 3 and 5 print “FizzBuzz”.

For the one guy who can cure Cancer with Python: do it without if-conditionals

Exercises

Random Insults

 

Create a class named `Insultor` that has a method `insult` that returns an insult.

An insult is the concatenation of three strings, selected from a list that we pass when we construct the object

Insultor

Improvements

  • Pass the list as input (check raw_input)
  • Selecting the strings can be done randomly
input = raw_input("Enter another insult word. Otherwise press enter")
while(input != "\n"):
    # Do something with input
    input = raw_input("Enter another insult word. Otherwise press enter")

import random
print random.randint(0,9)
