Finish the line of code that creates the areas list. Build the list so that the list first contains the name of each room as a string and then its area. In other words, add the strings "hallway", "kitchen" and "bedroom" at the appropriate locations. Print areas again; is the printou...
Updated List: ['apple', 'banana', 'cherry', 'orange'] Add Elements to a List From Other Iterables We use theextend()method to add elements to a list from other iterables. For example, numbers = [1,3,5]print('Numbers:', numbers) even_numbers = [2,4,6] # adding elements of o...
The PEP 484 -- Type Hints says that the types of elements of a tuple can be individually typed; so that you can say Tuple[str, int, float]; but a list, with List typing class can take only one type parameter: List[str], which hints that the difference of the 2 really is that t...

Sequence type: string, tuple, list 字符串:可以看成是单一字符的有序组合。字符串类型十分常用且单一字符串只表达一个含义,也被看作是基本数据类型。String: Think of it as an ordered combination of a single character. String types are very common and a single string that expresses only one meaning...
Other features of string slicing work analogously for list slicing as well:Both positive and negative indices can be specified: >>> a[-5:-2] ['bar', 'baz', 'qux'] >>> a[1:4] ['bar', 'baz', 'qux'] >>> a[-5:-2] == a[1:4] True Omitting the first index starts the...
A Python list is ordered, indexed (indices start at 0), mutable, heterogeneous (items need not be of the same type) and written CSV in square brackets.
