在用户输入的整数列表上应用max（）函数不会返回最大值吗？

Question

我想在用户提供的数字列表中找到最大值和最小值。

value = input("Please enter an integer separated by commas. :")

i = value.split(',')

value1 = max(i)
value2 = min(i)

print("max =", value1)

print("min =", value2)

执行代码并输入1,2,4,36,5结果

Please enter an integer separated by commas. :1,2,4,36,5
max = 5
min = 1

为什么max()函数返回5而不是36？

Answer 1

它们是字符串格式，所以。只需将它们映射为整数即可。

value = input("Please enter an integer separated by commas. :")

i=list(map(int, value.split(','))) #<---- Here
print(i)

value1 = max(i)
value2 = min(i)

print("max =", value1)

print("min =", value2)

Answer 2

将其转换为整数以获得适当的结果

value = input("Please enter an integer separated by commas. :")

i=value.split(',')
i = [int(x) for x in i]
value1 = max(i)
value2 = min(i)

print("max =", value1)

print("min =", value2)

OR

value = input("Please enter an integer separated by commas. :")

i=[int(x) for x in value.split(',')]

value1 = max(i)
value2 = min(i)

print("max =", value1)

print("min =", value2)

Answer 3

您应该将所有i元素都强制转换为int

value = input("Please enter an integer separated by commas. :") #input 1,2,4,36,5

i=[int(el) for el in value.split(',')]
value1 = max(i)
value2 = min(i)
print("max =", value1)
print("min =", value2)

OR
i = [int(el) for el in input("Please enter an integer separated by commas. :").split(',')] #input 1,2,4,36,5

value1 = max(i)
value2 = min(i)
print("max =", value1)
print("min =", value2)

输出
max = 36
min = 1

[原始代码使i中的元素成为字符串['1', '2', '4', '36', '5']，因此只需将它们更改为int，并且使min和max函数正常工作。
