The function below takes a single parameter, a list of numbers called number_list. complete the function to return a string of the provided numbers as a series of comma separate values (csv). for example, if the function was provided the argument [22, 33, 44], the function should return '22,33,44'. hint: in order to use the join function you need to first convert the numbers into strings, which you can do by looping over the number list to create a new list (via append) of strings of each number.

The solution code is written in Python 3.

Explanation:

Firstly, create a function, convertCSV(), that take one input which is a list of number, number_list. (Line 1)

Next, declare a new string list, str_list. (Line 2)

Use a for-loop to traverse the individual number in the number_list (Line 4) and add each of the number into the str_list. Please note, the individual number is converted to string type using Python str() method. (Line 5)

By now, the str_list should have a list of string type number. We can use join() method to join all the string element in the str_list into a single string and return it as an output. (Line 7) The "," acts as a separator between the element in the str_list.

We can  test the function by passing a random list of number, (e.g. [22,33,44]) and the output shall be '22,33,44'.  (Line 9 - 10)
