Computers are dumb

Language

Hint: its not English

Jython

Python in Java

Lesson 1: “Hello World!”

print “Hello World”

Lesson 2: Data Types

Integer 4,-2,100

Float 4.878, 2.0

String “Hello!123#$”

Lesson 3: Variables

Store data Jython gets it! X= “Hi” X = 5.67 X= 2

Quick Test

print 33 print “Hello” + “ “ + “World” + “!” print 22+3 print “22” + “3” print “22” + 3 print “22” * 3 print 5/3 x = 5

print x*3

How to start

def function():print “Hello World”

def otherFunction():print “Hello World Again!”

Indentation groups statements together

And then…

Save then LOAD!! Call your function

Class Exercise

1. Define a function(using the def keyword) called Lab1Program

2. Create a variable called name and place in it your name, e.g. name = “Maha”

3. Print out the statement: “My name is “ + name

4. Create a new variable called myNum, place the value 5.5 in it

5. Calculate the value of myNum*4, place the answer in the variable myNum

6. Print out myNum+3
