Operations: + - * /   (addition, subtraction, multiplication, division)

Variables: a number or symbol that represents a number or value, a place to store information

x=5

print x 

5 will show up

 

y= 10

print y

10 will show up

 

print x*y

50 will show up

 

print x+y  --> 15

print x-y   --> 5

print y-x  -->  -5

print y/x  --> 2

print x/y  --> 0 but will show 0.5 ONLY IF y=10.0 instead of just 10

B=20

r=99

print x+B-r will work but if you use capitals vs. lowercase it will not work unless you have defined the values!

 

string: anything you want printed surrounded by "" marks

lunch= "french fries, apple, burger, hot cheetos, round donut"

print lunch ----> french fries, apple, burger, hot cheetos, round donut

lunch= "french fries, burger, round donut"

print lunch ----> french fries, burger, round donut

If you change your variable later on in your program the PRINT function will only use the variable that you last used/updated!!! 

 

 

 

 

 

Python: the computer language that we use to create a program

Program:  what we type in the computer to make our computers do something

**all commands need to be lowercase **anything in the quotation marks will print even if it is misspelled.

          print "What is your favorite kholor?"    will show      What is your favorite kholor?
