tuple in python

"""tuples in python:
the lists are mutable, Python needs to allocate an extra memory block 
in case there is a need to extend the size of the list object after it is created. 
In contrary, as tuples are immutable and fixed size, Python allocates 
just the minimum memory block required for the data.
As a result, tuples are more memory efficient than the lists."""
import sys, platform, time
a_list = list()
a_tuple = tuple()
a_list = [1,2,3,4,5]
a_tuple = (1,2,3,4,5)
print(sys.getsizeof(a_list))
print(sys.getsizeof(a_tuple))
start_time = time.time()
b_list = list(range(10000000))
end_time = time.time()
print("Instantiation time for LIST:", end_time - start_time)
start_time = time.time()
b_tuple = tuple(range(10000000))
end_time = time.time()
print("Instantiation time for TUPLE:", end_time - start_time)
start_time = time.time()
for item in b_list:
  aa = b_list[20000]
end_time = time.time()
print("Lookup time for LIST: ", end_time - start_time)
start_time = time.time()
for item in b_tuple:
  aa = b_tuple[20000]
end_time = time.time()
print("Lookup time for TUPLE: ", end_time - start_time)

"""As you can see from the output of the above code snippet, 
the memory required for the identical list and tuple objects is different.
When it comes to the time efficiency, again tuples have a slight advantage 
over the lists especially when lookup to a value is considered."""

"""When to use Tuples over Lists:
Well, obviously this depends on your needs.
There may be some occasions you specifically do not what data to be changed. 
If you have data which is not meant to be changed in the first place, 
you should choose tuple data type over lists.
But if you know that the data will grow and shrink during the runtime of the application, 
you need to go with the list data type."""

properties of tuples in python

#Tuples are ordered, indexed collections of data
#Tuples can store duplicate values
#You cannot change the data of a tuple after that you have assigned it the values
#Like lists, it can also store several data items

tuple python

# Change Value In Tuple :-

friends = ("Mido", "Lucifer", "Abdelrhman")

# Example => Wanna Change ( Abdelrhman ) To ( Aiiob );
# First We Need Transformation From Tuple To List ,
# We Need To Create Variable With Any Name 
# After This We Use list() Function

oneName = list(friends)

# After This We Need Change The Value ,

oneName[-1] = "Aiiob"

# After This We Need Transformation From List To Tuple ,
# We Use tuple() Function

friends = tuple(oneName)

# And We Done (:

what are tuples in python

#A tuple is essentailly a list with limited uses. They are popular when making variables 
#or containers that you don't want changed, or when making temporary variables.
#A tuple is defined with parentheses.
Comment

tuple methods in python

#Python has two built-in methods that you can use on tuples.

#Method	Description

count()	
Returns the number of times a specified value occurs in a tuple

index()	
Searches the tuple for a specified value and returns the position 
of where it was found

what does tuple mean in python

Tuples Definition:
Tuples are used to store multiple items in a single variable. 
A tuple is a collection that is ordered and unchangeable.

There are 4 built-in data types:
-->Tuples
-->List
-->Set
-->Dictionary

Example of a Tuple:
coordinates = [(4,5), (6,7), (80,34)] 
#Coordinates are a very common example of a tuple
