3. Computers are dumb

4. Language Hint: its not English

5. Jython Python in Java

6. Lesson 1: “Hello World!” print “Hello World”

7. Lesson 2: Data Types  Integer  4,-2,100  Float  4.878, 2.0  String  “Hello!123#$”

8. Lesson 3: Variables  Store data  Jython gets it!  X= “Hi”  X = 5.67  X= 2

9. 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

11. How to start def function(): print “Hello World” def otherFunction(): print “Hello World Again!” Indentation groups statements together

12. And then…  Save then LOAD!!  Call your function

13. 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.
