Parser

Write a function which converts a string representation of a table of integers to a list of lists of integers. The elements of a row are separated by commas and rows are separated by semicolons. Test your function with

'1,2,3;4,5,6;7,8,9'

Result should be

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]

Bonus: Solve the task in one line.

Spoon Language

Write a Python script which prompts the user for some input and translate user input to spoon language.

Hint: Simple replacement does not work. If, for instance, at first a is replaced by alewa, subsequent replacement of e will alter the lew in alewa. There seems to be no replacement order for vowels working correctly in each case. Thus, in a first run replace all vowels by some code (unlikely to appear in a text), then, in a second run, replace the codes by the vowel’s lew-version.
