Other difference with Perl: Python scripts in a pipe

[Fillmore]

when I put a Python script in pipe with other commands, it will refuse 
to let go silently. Any way I can avoid this?

$ python somescript.py | head -5
line 1
line 3
line 3
line 4
line 5
Traceback (most recent call last):
   File "./somescript.py", line 50, in <module>
     sys.stdout.write(row[0])
BrokenPipeError: [Errno 32] Broken pipe
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' 
encoding='UTF-8'>
BrokenPipeError: [Errno 32] Broken pipe

thanks
