 # A comment, this is so you can read your program later.
 # Anything after the # is ignored by python.

print ("I could have code like this.") # and the comment after is ignored

 # You can also use a comment to "disable" or comment out a piece of code:
 # print "This won't run."

print ("This will run.")
I could have code like this.
This will run.

print ("How about some more." )
print ("Is it greater?", 5 > -2)
print ("Is it greater or equal?", 5 >= -2 )
print ("Is it less or equal?", 5 <= -2)
I will now count my chickens:
Hens 30.0
Roosters 97
Now I will count the eggs:
6.75
Is it true that 3 + 2 < 5 - 7?
False
What is 3 + 2? 5
What is 5 - 7? -2
Oh, that's why it's False.
How about some more.
Is it greater? True
Is it greater or equal? True
Is it less or equal? False

There are 100 cars available.
There are only 30 drivers available.
There will be 70 empty cars today.
We can transport 120.0 people today.
We have 90 to carpool today.
We need to put about 3.0 in each car.
