Oops! Clearly,
b in "\r\n\t"
is preferable to ...
b in list("\r\n\t")

Dennis Lee Bieber presented a code snippet with two consecutive statements
that made me think, "I'd code this differently". So just for fun ... is
Dennis's original statement or my "_alt" statement more idiomatically
Pythonic? Are there even more Pythonic alternative codings?

Define binary content.

Step one: read the file.
Step two: does any of the data you have read match

There is no such thing as a unicode file. You most likely mean UTF-8 or
UTF-16 coded text.

Yes, check the file size. If it's non-zero, then it has binary
content.

All files are binary, but probably by binary you mean non-text.
There are lots of ways to decide if a file is non-text, but I don't know
of any "standard" way. You can detect a file as not-ascii by simply
searching for any character greater than 0x7f. But that doesn't handle

There are lots of ways to decide if a file is non-text, but I don't know
of any "standard" way. You can detect a file as not-ascii by simply
searching for any character greater than 0x7f. But that doesn't handle
a UTF-8 file, which is an 8bit text file representing Unicode.
The way I've see
or rather:
#!/usr/bin/env python
import string
def isbin(filename):
fd=open(filename,'rb')
for b in fd.read():
if not b in string.printable and b not in string.whitespace:
fd.close()
return True
fd.close()
return False
for f in ['/bin/bash', '/etc/passwd']:

There might be another way but off the top of my head:
#!/usr/bin/env python
def isbin(filename):
fd=open(filename,'rb')
for b in fd.read():
if ord(b) > 127:

return True
fd.close()
return False

Hi,
I'm wondering if Python has a utility to detect binary content in
files? Or if anyone has any ideas on how that can be accomplished? I
haven't been able to find any useful information to accomplish this
(my other option is to fire off a perl script from within m python
