第一个参数str是要查找的字符串。 第二个参数strlist是要搜索的逗号分隔的字符串列表 FIND_IN_SET()函数根据参数的值返回一个整数或一个NULL值: 如果str或strlist为NULL,则函数返回NULL值。 如果str不在strlist中,或者strlist是空字符串,则返回零。 如果str在strlist中,则返回一个正整数。 I
if num < min_value: min_value = num return max_value, min_value lst = [5, 3, 9, 1, 7] max_val, min_val = find_max_min(lst) print("最大值:", max_val) print("最小值:", min_val) ```相关知识点: 试题来源: 解析 解析:该程序定义了一个函数`find_max_min`,接受一个列表作...

If we find an index where the element is greater than the element at indexmax_index, we will assign the current index to the variablemax_index. After iteration of the entire list, we will get the index of the maximum element in the variablemax_index. ...

In this tutorial, we will discuss how to find the mode of a list in Python. Themax()function can return the maximum value of the given data set. Thekeyargument with thecount()method compares and returns the number of times each element is present in the data set. ...
