Punishment

Instructions

Often in schools we are asked to copy hundreds of sentences in order to better remember not to do something, this punishment is very old and quite boring!

Hopefully we now have Python that can do the job for us. In order to do so create a file punishment.py which will contain a function do_punishment having 3 arguments:

  • first_part: which will be a string.
  • second_part: which will be also a string.
  • nb_lines: which will be a number.

Here is the prototype of the function:

def do_punishment(first_part, second_part, nb_lines):

The function will concatenate first_part and second_part, adding a space in between them and a . at the end of second_part. It will repeat this process for nb_lines times.

The function will return a single string containing all the repeated sentences.

In case first_part and second_part have empty spaces at the start or at the end those spaces should be trimmed (removed from the strings).

Usage

Here is a possible test.py to test your functions:

import punishment

print(punishment.do_punishment('   The first half   ', '   and the second  ', 4), end='')
print(punishment.do_punishment('Will not', 'show', 0), end='')
print(punishment.do_punishment('', '', 3), end='')
$ python test.py
The first half and the second.
The first half and the second.
The first half and the second.
The first half and the second.
 .
 .
 .

Hints

  • Removing spaces at the start and end of a string is so common that almost all languages implement this feature. Here you can check for the strip() method.
  • Instead of using loops you can try the string multiplication operator, which is a very nice feature of Python and will make your code more readable.
