Syntax

About elif

elif allows you to chain together multiple if statements. It will only ever run one of the statements which is different to having separate if statements where multiple ones could be triggered.

Here is the code from the video. Try this code out for yourself.

age = int(raw_input("how old are you?"))
if age < 0:
	print "error"
elif age == 1:
	print "baby"
elif age < 4:
	print "toddler"
elif age < 10:
	print "young child"
elif age < 17:
	print "teen"
elif age < 60:
	print "adult"
else:
	print "OAP"
