Python list functions

Lists in Python
 Python offers a range of compound datatypes
often referred to as sequences.
 Lists are a useful tool for preserving a sequence
of data and further iterating over it.
 Note:Like variables store 1 value, lists can be
used to store multiple values.

Lits has 4 atrributes
 Name of the list
 Values inside the list
 Length of list
 Calculated by len(list)
 Indexes of list
 Indexes of list start with 0 to (len(list) – 1)

Strings are stored as lists in python

Functions in python
 In Python, function is a group of related
statements that perform a specific task.
 Functions help break our program into smaller
and modular chunks.
 As our program grows larger and larger,
functions make it more organized and
manageable.

Scope and Lifetime of variables
 Scope of a variable is the portion of a program
where the variable is recognized. Parameters
and variables defined inside a function is not
visible from outside. Hence, they have a local
scope.
 Lifetime of a variable is the period throughout
which the variable exits in the memory. The
lifetime of variables inside a function is as long
as the function executes.
 They are destroyed once we return from the
function. Hence, a function does not remember
