如何使python函数更好？

我目前正在创建一个函数，允许用户输入最高的整数

代码：

---

当我尝试输入值3001000200时，它总是返回300，很明显它应该是1000。有人有解决方案吗？

将字符串转换为整数：

def max_num(x,y,z):

    if int(x)>=int(y) and int(x)>=int(z):
       return x
    elif int(y)>=int(x) and int(y)>=int(z):
       return y
    else:
       return z

num1= input("1st value: ")

num2= input("2nd value: ")

num3= input("3rd value: ")

print("The highest integer is:",max_num(num1,num2,num3))

---

只需使用预先定义的max（）函数：

---

尝试使用max函数

def max_num(x,y,z):
      return (max(x,y,z))

输出

higher num has been found 2
higher num has been found 3
higher num has been found 10
1 is not higher than 10

1000>300，但“1000”<“300”是的，将这些字符串转换为整数。

input

返回字符串。你在比较这些。不是它们所表示的关于

max（（num1，num2，num3））

？

max（'300'，'1000'）

->

'300'

m的整数，同样，练习可能是创建一个用户定义的

max

，而不是简单地查找最大值。最好指出根本问题，而不是提供他们可能不需要的解决方案

num1= int(input("1st value: "))
num2= int(input("2nd value: "))
num3= int(input("3rd value: "))

print("The highest integer is:",max_num(num1,num2,num3))

def max_num(x,y,z):
      return (max(x,y,z))

def max_num(*args):
    highestNum = 0
    for num in args:
        if num > highestNum:
            highestNum = num
            print("higher num has been found " + str(highestNum))
        else:
            print(str(num) + " is not higher than " + str(highestNum))

max_num(2,3,10,1)

higher num has been found 2
higher num has been found 3
higher num has been found 10
1 is not higher than 10
