Python中用于多个选择, else if 用 elif表示。

例如：

>>> x = 3
>>> if x<1:
        print " x is less than 1. "
    elif x<5:
        print " x is less than 5. "
    elif x<7:
        print " x is less than 7. "
    else:
        print "x is not less than 7. "

该 if 语句从上往下判断，在第二个判断上是True，则执行其对应的语句。打印出x is less than 5. 之后就忽略掉剩下 elif 和 else.

s = ['a', 'b', 'c', 'd']
s[s.index('c')] = 'chinese'
print s
print 'd' * 80
for index, value in enumerate(s):
    if 'd' in value:
        s[index] = 'Japan'
    elif 'b' in value:
        s[index] = 'China'
    else:
        pass
print s
