`min()`是Python 3中的内置函数。它返回可迭代中的最小项或两个或多个参数中的最小项。
|
|||
|
|
|
|||
|
|
## 参数
|
|||
|
|
|
|||
|
|
此函数将两个或多个数字或任何类型的iterable作为参数。在给出一个iterable作为参数时，我们必须确保iterable中的所有元素都是相同的类型。这意味着我们无法传递一个包含字符串和整数值的列表。
|
|||
|
|
|
|||
|
|
有效参数：
|
|||
|
|
```
|
|||
|
|
min(2, 3)
|
|||
|
|
min([1, 2, 3])
|
|||
|
|
min('a', 'b', 'c')
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
参数无效：
|
|||
|
|
```
|
|||
|
|
min(2, 'a')
|
|||
|
|
min([1, 2, 3, 'a'])
|
|||
|
|
min([])
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 回报价值
|
|||
|
|
|
|||
|
|
返回iterable中的最小项。如果提供了两个或多个位置参数，则最小的位置参数
|
|||
|
|
被退回。如果iterable为空并且未提供default，则引发ValueError。
|
|||
|
|
|
|||
|
|
## 代码示例
|
|||
|
|
```
|
|||
|
|
print(min(2, 3)) # Returns 2 as 2 is the smallest of the two values
|
|||
|
|
print(min(2, 3, -1)) # Returns -1 as -1 is the smallest of the two values
|
|||
|
|
|
|||
|
|
list1 = [1, 2, 4, 5, -54]
|
|||
|
|
print(min(list1)) # Returns -54 as -54 is the smallest value in the list
|
|||
|
|
|
|||
|
|
list2 = ['a', 'b', 'c' ]
|
|||
|
|
print(min(list2)) # Returns 'a' as 'a' is the smallest in the list in alphabetical order
|
|||
|
|
|
|||
|
|
list3 = [1, 2, 'abc', 'xyz']
|
|||
|
|
print(min(list3)) # Gives TypeError as values in the list are of different type
|
|||
|
|
|
|||
|
|
#Fix the TypeError mentioned above first before moving on to next step
|
|||
|
|
|
|||
|
|
list4 = []
|
|||
|
|
print(min(list4)) # Gives ValueError as the argument is empty
|
|||
|
|
```
