So we know that if statements rely on a condition (true or false) to see if the code inside the if will run or not. However sometimes we may need to use more than one condition or maybe check for the opposite (negative). The code below shows the use of the key word not. This will take any true or false value and invert it. So true becomes false and false becomes true.

a = True
b = False
if not a:
   print "a is true"
else:
   print "a is not true"

There are two ways we can connect conditions together in a if statement. You can use the and keyword and the or keyword. Run the code below to see an example of the and connective.

age = 63
name = "bert"
if age < 40 and name == "bert":
    print "young bert"
if age > 40 and name == "bert":
    print "old bert"
