Python Code Reviewer Task

Your mission is to create a program that reviews Python code. The solution can be written in any language!

It must take input that contains python code. The program must add # This is not pythonic! before each block of non-whitespace lines.

Input


The data can be entered via stdin.
The data will contain at least 3 lines with one blank one in between
them.


Minimum input example. 

print "Hello World!"

Print "Bye World!"


Sample Input

from os.path import abspath

lines = []
with open(__file__, 'r') as f:
    for line in f:
        lines.append(line)

if lines is not None:

    newLines = []
    hasReviewedBlock = False

    for line in lines:
        if len(line) &gt; 1: # \n
            if hasReviewedBlock == False:
                newLines.append("# This is not pythonic!\n")
                hasReviewedBlock = True
        else:
            hasReviewedBlock = False

        newLines.append(line)
    with open("d:/test.py", 'w') as f:
        for line in newLines:
            f.write(line);


Output

Output has to be written to STDOUT or closest alternative.

Sample Output

# This is not pythonic!
from os.path import abspath

# This is not pythonic!
lines = []
with open(__file__, 'r') as f:
    for line in f:
        lines.append(line)

# This is not pythonic!
if lines is not None:

# This is not pythonic!
    newLines = []
    hasReviewedBlock = False

# This is not pythonic!
    for line in lines:
        if len(line) &gt; 1: # \n
            if hasReviewedBlock == False:
                newLines.append("# This is not pythonic!\n")
                hasReviewedBlock = True
        else:
            hasReviewedBlock = False

# This is not pythonic!
        newLines.append(line)
    with open("d:/test.py", 'w') as f:
        for line in newLines:
            f.write(line);


Scoring:

Lowest number of bytes wins. -5 bytes if your program can be used as valid input.
awk, 64 56 54 bytes
/^$/{i=0}/./{if(!i++)print&quot;# This is not pythonic!&quot;}1

Test:
echo '/^$/{i=0}/./{if(!i++)print&quot;# This is not pythonic!&quot;}1' &gt; solution.awk
awk -f solution.awk &lt; pyth.py
awk -f solution.awk &lt; pyth.py

Explanation:
/^$/ - matches empty line,
/./ - matches non-empty line,
1 - matches each line. No body is equivalent to {print;} - each line of input is printed.
