1.写函数，接收两个数字参数，返回最大值 def res_max(number1,number2):l1 = []l1.append(number1)l1.append(number2)return max(l1) 2.写函数，获取传入列表的所有奇数位索引对应的元素，并将其作为新列表返回 。def getnewlist(mylist):list1=[];for i in range(0,len(mylist)):if i%2!=0:list1.append(mylist[i])return list1 3.写函数，检查传入的字符串是否含有空字符串，返回结果，包含空字符串返回True，不包含返回False def str_spack(string):if string.find(\\\' \\\'):return Trueelse:return False 4.定义一个函数,实现两个数四则运算,要注意有3个参数,分别是运算符和两个运算的数字. def arithmetic(number1, number2, symbol):if symbol == \\\' \\\':s = number1number2elif symbol == \\\'-\\\':s = number1 - number2elif symbol == \\\'*\\\':s = number1 * number2elif symbol == \\\'/\\\':s = number1 / number2 return s方法二：def getresult(num1,fh,num2): str1=str(num1) fh str(num2) return e
