Question

Write 6 functions for list and give the example to explain the same
​

Answer 1

Answer:

list is an ordered set of values, where each value is identified by an index. The values that make up a list are called its elements. Lists are similar to strings, which are ordered sets of characters, except that the elements of a list can have any type. Lists and strings — and other things that behave like ordered sets — are called sequences.

9.1. List values

There are several ways to create a new list; the simplest is to enclose the elements in square brackets ( [ and ]):

[10, 20, 30, 40]

["spam", "bungee", "swallow"]

The first example is a list of four integers. The second is a list of three strings. The elements of a list don’t have to be the same type. The following list contains a string, a float, an integer, and (mirabile dictu) another list:

["hello", 2.0, 5, [10, 20]]

A list within another list is said to be nested.

Finally, there is a special list that contains no elements. It is called the empty list, and is denoted [].

Like numeric 0 values and the empty string, the empty list is false in a boolean expression:

>>> if []:

... print 'This is true.'

... else:

... print 'This is false.'

...

This is false.

Answer 2

Functions can be stored as elements of a list or any other data structure in Python. For example, if we wish to perform multiple operations to a particular number, we define apply_func(L, x) that takes a list of functions, L and an operand, x and applies each function in L on x.
