Whole Data lists: [['Apple(34Rs)', 'Banana(56Rs)'], ['Orange(66RS)', 'Peach(22)']] Desired Data is: True 2.Search list of lists using any() function in Python Theany()function allows for a concise syntax to determine the presence of a specific item in a list of lists. By ...
In this example, you create a list of countries represented by string objects. Because lists are ordered sequences, the values retain the insertion order.Note: To learn more about the list data type, check out the Python’s list Data Type: A Deep Dive With Examples tutorial....

3)Lists(列表)——列表就是一些值的有序集合,我们用方括号声明列表; colors=[‘red’,’green’,’blue’] type(colors) <class ‘list’> 4)tuples(元组)——元组和列表一样,也是一些值的有序集合,区别是元组是不可变的,意味着我们无法改变元组内的值。
“m = p.search('abbcabd')”在'abbcabd'中不断向后查找,只返回第一个最先匹配到的内容,不从第一个字符开始“硬性匹配” “listAll = p.findall('abbcabd')”在'abbcabd'中不断向后查找所有能匹配的内容,并将其以列表的方式返回 “iterAll = p.finditer('abbcabd')”上一种方式的迭代器版本,迭代...
Both examples work the same as the list-focused examples. In the first example, the in operator returns True because the target value, 5, is in the tuple. In the second example, not in returns the opposite result.For lists and tuples, the membership operators use a search algorithm that...

Searching for elements in a sorted list can be much more efficient compared to an unsorted list. In this section, we’ll discuss three methods for finding elements in sorted lists: Binary Search, Bisect_left, and Bisect_right. Binary Search ...
