How to append to a list in python using for loop?

This recipe helps you append to a list in python using for loop

Recipe Objective

While working with list, there is a consistent need of modifying it, particularly adding new elements to it.

So this recipe is a short example on how to append a list in python. Let's get started.

Step 1 - Defining list_append function

def list_append(x): return [x*2,x*3],x*4,x*5

We have created a simple function that returns multiples of values passed in it.

Step 2 - Defining test example and appending it

Take any example of a list. In 2nd line of code, we call append function and it call's our predefined function to receive values.

table=[11] table.append(list_append(11))

Firstly, list_append function bring in a multiple of 11 in appended braces. Thereby the append function receives inputs and simply reflect onto the table list.

Step 3 - Printing list

Simply use print function to print the newly appended list.

print(table)

Step 4 - Lets look at our dataset now

Once we run the above code snippet, we will see:

[11, ([22, 33], 44, 55)]
