Sometimes you only want to run lines of script if a condition is true. In an instance of that sort, you tell the program, “If condition 1 is true, then execute one set of commands. Otherwise, execute another set of commands.” Add the following lines to your script:
for number in range(5):
if
cows > 1:
print "Join us for a barbeque"
cows = cows -1
elif
cows == 1:
print "Last barbeque today"
cows = cows -1
else:
print "No barbeque today"
Now run the program. With these lines, we have embedded an “if” statement inside of a “for” loop. So, the program looped through the “if” statement 5 times. Each time lines were only executed if they met one of the “if” conditions. Notice that we used “elif” to add a condition. “elif” is just the Python way of saying “or else if”. When an instance does not fit any of the conditions the script runs the statements under “else”.
Note: make sure you use two equal signs together when you're testing for an equal condition (“==”). That way Vizard knows that you're comparing the value of a variable and not setting that variable equal to something else.
