The answer is yes we can, but no we won't.
You wouldn't learn anything if we did and
this list is here to teach.
That means you need to write the code and
we will offer help and suggestions.

Can you read a line of input and extract 2 numbers?
Can you write a loop that repeats as often as one
of the numbers you read?
Can you write a print statement that outputs as many '*'s as the other
If so, put it together and jobs done.
If not do what you can and show us the result.

Read a number.
Shift the letters - this is probably easiest with slicing
and a wee bit of slightly tricky arithmetic
Read the input word
Now use the two lists of letters to map each letter (hint Python has
some string functions that do precisely this.)
