The distinction between lists and tuples has been described in terms of usage. However, there is a more fundamental difference: in Python, lists are mutable, while tuples are immutable(分清楚列表是可变的,元组是不可变的). In other words, lists can be modified, while tuples cannot. Here are...
Lists are represented by boxes with the word “list” outside and the elements of the list inside.cheesesrefers to a list with three elements indexed 0, 1 and 2.numberscontains two elements; the diagram shows that the value of the second element has been reassigned from 123 to 5.emptyrefe...
whereas lists are sequences of any type of Python objects. 字符串和列表之间的另一个区别是字符串是不可变的,而列表是可变的。 Another difference between strings and lists is that strings are immutable, whereas lists are mutable. 除了这两个区别之外,字符串和列表当然也有自己的方法。 In addition to...
1 Tuples are immutable ▲元组与列表类似,但是它不可改变 ▲元组常用()括号表示 >>> t = ('a', 'b', 'c', 'd', 'e') 1. ▲ 创建只包含一个元素的元组需要加逗号,否则认为是字符 >>> t1 = ('a',) >>> type(t1) <type 'tuple'> ...
L[2]+1 ---evaluates to 5---这个是tuple就明显有区别了,tuple是immutable。 L[3] ---evaluates to [1, 2] L[4] ---gives an error Changing elements lists are mutable assigning to an element at an index changes the value L =
Python has mutable and immutable data types. Mutable types, such as lists and dictionaries, allow you to change or mutate their values in place. In contrast, immutable types, like numbers, strings, and tuples, don’t allow you to modify their values in place....
Understanding Lists in Python 3 Adding Named Fields to Tuples Python tuples are an immutable, or unchangeable, ordered sequence of elements. Tuples are frequently used to represent columnar data; for example, lines from a CSV file or rows from a SQL database. An aquarium might keep track of...
The basic difference between them should be obvious for anyone who has spent more than a few hours with Python—lists are dynamic so can change their size, while tuples are immutable (they cannot be modified after they are created).
These data types also support the standard comparison operators. Like with strings, when you use a comparison operator to compare two lists or two tuples, Python runs an item-by-item comparison.Note that Python applies specific rules depending on the type of the contained items. Here are some...
