2.2. Find the Smallest String in Array Just like withmax(),min()can be used with thekeyargument to find the shortest string. fruits=["apple","banana","cherry","date"]shortest_fruit=min(fruits,key=len)print(shortest_fruit)# Output: "date" 2.3. Find Min Key or Value in a Dictionary ...
arr=np.array([4,2,9,1,7])min_val,min_index=find_min(arr)print("最小值:",min_val)print("最小值位置:",min_index) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 上述代码中,我们首先导入numpy库,并定义了一个find_min()函数。在函数中,np.min()函数用来找到数组中的最小值,而np...
使用max()和min()方法在可比较元素的集合(例如列表,集合或数组)中查找最大(或最小)项的Python示例。 1. Python max() function max()该功能用于– 计算在其参数中传递的最大值。 如果字符串作为参数传递,则在字典上的最大值。 1.1. Find largest integer in array ...
