You can write nested lists, which means lists inside lists live the above example.Also, you can access any element of the list by its index which is zero based.third_elem = mylist[2]There are some similarities with strings. You can review the Python programming basics post....
下面开始分析，t1是不可变的元祖，在t1内包含一个列表['I','am','inside']，我们知道列表是可变的，我们首先通过id()函数获取列表的标识符，即内存地址45954512，然后试图通过赋值语句t1[4]=['I am coming']更改t1，结果自然是失败的。怎么办呢？既然t1[4]是列表，那就可以用List的方法嘛，于是我们先用clea...
Similar to tuples, lists can contain one or more lists inside them and can be accessed via subsequent square brackets. The same "tree" representation can be used to illustrate the nesting of lists. An example of accessing the elements from a nested list is shown below. >>> a = [['Enjo...
>>> T[1][0] = 'spam' # This works: can change mutables inside >>> T (1, ['spam', 3], 4) === eval能够把字符串当做可执行程序代码(从技术上来讲,就是一个含有Python表达式的字符串) >>> line = "[1,2,3]${'a':1, 'b':2}\n" >>> line "[1,2,3]${'a':1, 'b':2...
Python Tuple A tuple is a collection similar to aPython list. The primary difference is that we cannot modify a tuple once it is created. Create a Python Tuple We create a tuple by placing items inside parentheses(). For example, numbers = (1,2,-5)...

Certainly, in Python, you can nest tuples inside other tuples to create multi-dimensional data structures. This concept is known as tuple nesting. By nesting tuples, you can represent complex and hierarchical data in a concise and organized manner. Each inner tuple can contain its own set of...
name = "python" for name1 in name: print(name1) p y t h o n 2, use for and enumerate for index,name in enumerate(listname) print(index,name) for index,pyl in enumerate("python"): print(index,pyl) 0 p 1 y 2 t 3 h
Tuple inpythonis basically like arrays in other languages like Java. 30th Nov 2016, 3:23 PM Resurektzz7 + 3 A tuple is a sequence of objects. It's similar to a list, but tuples are immutable, so you cannot change the values of the objects inside a tuple, as you can do in a ...
nestedTuple = ("hello", ("python", "world")) 2. Accessing Tuple Items We can access tuple items using indices inside square brackets. Positive index begins counting from start of tuple. Negative index begins counting from end of tuple. A range of index will create a new tuple (called Sl...
