10.9 New exercise , before existing set

[Sandy Garner]

Make a text file with a series of integers e.g. 35 15 353 1 30 54 44 501

Write a function which will take a string parameter and print out that
string with a "$" sign before it and ",000" after it.

In the main routine, write code to open the file, read the contents to a
string, split the string into a list of "words" and use a for loop to send each
word to the function you wrote.

"""

"""
Extension:
Add K to some of the integers of the text file e.g. 35K 15 353K 1K 30 54K
44K 501
Adapt the function so it can remove the K if it is present, producing the
same output as before.
