An "elif" condition is only tested if the previous "if" test was false. When you use another "if" instead of "elif", then the second condition will always be tested, no matter what the result of the first one was.

Proper use of "elif" will usually make the program more efficient, plus it allows you to use logical progressions that would not work with a plain "if". For example:

if value > 60:
    print "Large"
elif value > 30:     # a plain "if" would not work here
    print "Medium"
else:
    print "Small"

Substituting a plain "if" for the "elif" would cause a value over 60 to print out both "Large" and "Medium".
