The function below takes one parameter: a string (date_string) containing a date in the mm/dd/year format. Complete the function
Natalija [7]

Answer:

The solution code is written in Python 3.

  1. def convertDate(date_string):
  2.    date_list = date_string.split("/")
  3.    for i in range(0, len(date_list)):
  4.        date_list[i] = int(date_list[i])
  5.    return date_list  
  6. print(convertDate('06/11/1930'))

Explanation:

Firstly, create a function convertDate() with one parameter, <em>date_string</em>. (Line 1).

Next, use the Python string <em>split()</em> method to split the date string into a list of date components (month, day & year) and assign it to variable <em>date_list</em>. (Line 3) In this case, we use "/" as the separator.

However, all the separated date components in the <em>date_list</em> are still a string. We can use for-loop to traverse through each of the element within the list and convert each of them to integer using Python<em> int() </em>function. (Line 5 - 6)

At last return the final date_list as the output (Line 8)

We can test our function as in Line 11. We shall see the output is as follow:

[6, 11, 1930]
