Lecture 1: Control flow, loops and functions

Booleans:

Before we start with control flow, let's introduce a new variable type called the boolean. This is used to signify  if something is true or false .

Programs 1: 

Happy = True

Sad= False

print 'Am I happy? %s. Am I sad? %s.' % (Happy,Sad)

output : 

Am I hungry? True. Am I thirsty? False.

The if/else statement:

The if/else statement is used to make decisions based on the value of a variable. The general format of the if/else statement is as follows:

Programs 2: 

days_in_feb = 29 # number of days in february

if days_in_feb != 29:

        print 'We are not in a leap year'

else:

        print 'We are in a leap year.'

Output 2:

We are in a leap year.
