You can access tuple items by referring to the index number, inside square brackets:ExampleGet your own Python Server Print the second item in the tuple: thistuple = ("apple", "banana", "cherry") print(thistuple[1]) Try it Yourself » ...
for element in my_list: #access elements one by one print(element) print(my_list) #access all elements print(my_list[3]) #access index 3 element print(my_list[0:2]) #access elements from 0 to 1 and exclude 2 print(my_list[::-1]) #access elements in reverse 其他功能 在处理列表...
To access the items in a sublist, simply append an additional index:索引也是根据嵌套来的>>> x[1] ['bb', ['ccc', 'ddd'], 'ee', 'ff'] >>> x[1][0] 'bb' >>> x[1][1] ['ccc', 'ddd'] >>> x[1][2] 'ee' >>> x[1][3] 'ff' >>> x[3] ['hh', 'ii'] >>...
So if we call this sequence "s", we would access the first element in our sequence by typing "s" and, in brackets, putting its location, which is 0. 这个位于第二个位置的对象将作为s[1]进行寻址和访问,依此类推。 This object here in the second position would be addressed and accessed ...

remove removes the first matching value, not a specific index, raises ValueError if the value is not found. pop removes the element at a specific index and returns it, raises IndexError if an invalid index is specified.Why the output is [2, 4]?The...
Tuple items are indexed, the first item has index[0], the second item has index[1]etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not change. Unchangeable Tuples are unchangeable, meaning that we cannot change, add ...
Lists, tuples, and strings are subscriptable, but sets are not. Attempting to access an element of an object that isn’t subscriptable will raise a TypeError.Mutability is a broader topic requiring additional exploration and documentation reference. To keep things short, an object is mutable if ...
