To get the index of the maximum element in a list, we will first find the maximum element with themax()function and find its index with theindex()function. Example: lst=[1,4,8,9,-1]m=max(lst)print(lst.index(m)) Output:
Once we get the length of the list, we will use therange()function and a for loop to iterate over the list. While iteration, at each index in the list, we will check if the element at the current index is greater than the element at the indexmax_index. If we find an index where...
存储整数、小数、字符串、列表、元组等任何类型的数据,同一个列表中元素的类型也可以不同,格式为:[element1 , element2 , element3 , ... , elementn],其中,listname 表示变量名,element1 ~ elementn 表示列表元素。 列表的创建 Python 中,创建列表的方法可分为两种。 1)使用 [] 创建列表 [] ...
(1)append(element):将元素element添加到列表的末尾。 In [59]: example_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] In [60]: example_list.append(11) In [61]: example_list Out[61]: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11] (2)insert(position, element):将元素element插...
# Get all combinations of [1, 2, 3] # and length 2 comb = combinations([1,2,3],2) # Print the obtained combinations foriinlist(comb): print(i) 输出: (1,2) (1,3) (2,3) 组合按输入的字典排序顺序发出。因此,如果输入列表已排序,则组合元组将按排序顺序生成。
