This program searches for python source code two different ways.
	- It prints a list of every *.py *.pY *.Py *.PY file in the given subtree.
	- It prints a list of every file that contains the regular expression "from \w* import \w*" or "from \w* import \*" anywhere in the first 10 lines.


Hint:  Use walk to search the file tree
Use readlines to read the lines of the file
Remember that you can array slice
Use search to examine the lines for the regular expressions
