If you haven't read if else do that first.
elif allows you to extend your choices to more than just the two available with if else.
Now you can have
if
elif
elif
elif
elif (as many as you need)
else
Adventure Game Example
choice = input("Type a to attack, b to back away or c to creep past.") #User chooses a, b or c
if choice == ("a"):
print("You attack with your terrible sword")
elif choice == ("b"):
print("You back away quietly")
else:
print("Carefully you sneak past")
Note it is possible for the user to type something other than a, b or c. In this case it would go to the else command.
Web Page Menu Example
import webbrowser
bbc = ("http://www.bbc.co.uk")
newsround = ("http://www.bbc.co.uk/newsround")
yahookids = ("http://kids.yahoo.com/")
moshi = ("http://www.moshimonsters.com/")
choice = input("""
Type
a for BBC
b for Newsround
c for YahoohKids
d for Moshi Monsters""")
if choice == ("a"):
webbrowser.open(bbc)
elif choice == ("b"):
webbrowser.open(newsround)
elif choice == ("c"):
webbrowser.open(yahookids)
else:
webbrowser.open(moshi)
#Webbrowser opens web pages
