【python】函数参数-任意参数

def min1(args):
    res=args[0]
    for arg in args[1:]:
        if arg<res:
            res=arg
    return res

def min2(first,rest):
    for arg in rest:
        if arg<first:
            first=arg
    return first

def min3(args):
    tmp=list(args)
    tmp.sort()
    return tmp[0]
print 'Please in put a min func from min1,min2,min3\n'
print 'min1(*args) min2(first,*rest) min3(*args)\n'
print 'Please input a sequence to min1 and min3\n'
inputword=raw_input()
inputword=inputword.split(',')
print 'Please input  first  parameter to min2\n'
first=raw_input()
print 'Please input  second parameter to min2\n'
second=raw_input()
second=second.split(',')
print min1(inputword),'-----------',min2(first,second),'-----------',min3(inputword)
raw_input()

如果函数写成*args的任意参数形式，则args会被识别成(['1', '2', '3'],)这样的元组，因此不能满足需求。
