Check whether a path exists on a remote host using paramiko
See the errno module for constants defining all those error codes. Also, it's a bit clearer to use the errno attribute of the exception than the expansion of the __init__ args, so I'd do this:
except IOError, e: # or "as" if you're using Python 3.0 if e.errno == errno.ENOENT: ...
There is no "exists" method defined for SFTP (not just paramiko), so your method is fine.
I think checking the errno is a little cleaner:
def rexists(sftp, path): """os.path.exists for paramiko's SCP object """ try: sftp.stat(path) except IOError, e: if e[0] == 2: return False raise else: return True
