A data science experiment you are conducting has retrieved two historical observations for the price of Bitcoin(BTC) on December 2, 2017 of 11234 and 12475. Create a Python script that stores these two historicalobservations in a list variable namedbtcdec1.Your data science experiment requires four additional data tasks. The first task is to use the listappend()method to add the BTC price of 14560 to the listbtcdec1. The second task is to create a new empty listnamedbtcdec2and append the BTC prices of 15630, 12475, and 14972. The third task required you to usethe listextend()method to add the contents ofbtcdec2into the listbtcdec1. The fourth and final taskrequires you to use the listsort()method of the listbtcdec1to sort the items in the newly extended list, then use theprintstatement to output the content of listbtcdec1to the Python console. Starter code:.

Following are the code to this question:

btcdec1=[11234, 12475] #defining a list btcdec1 that holds two integer values  

btcdec1.append(14560)#using append method to add value in btcdec1 list

btcdec2=[]#defining an empty list btcdec2

btcdec2.append(15630)#using append method to add value in btcdec2 list

btcdec2.append(12475)#using append method to add value in btcdec2 list

btcdec2.append(14972)#using append method to add value in btcdec2 list

btcdec1.extend(btcdec2)#using the extend method to add value list into btcdec1

btcdec1.sort()#using sort method to arrange value in ascending order

print(btcdec1)#print list btcdec1

Output:

[11234, 12475, 12475, 14560, 14972, 15630]

Explanation:

In this code a list "btcdec1" is declared, which holds two integer variables, in the next step, it uses the append method to add another element into the list.

In the next step, another empty list "btcdec2" is declared, which uses the append method to hold the integer element, and uses the extend and sort method to add the second list into the first one and then sort the whole list and print its values.
