I'm an experienced C/Java/Perl developer learning Python.
What's the canonical Python way of implementing this pseudocode?
String buf
File f
while ((buf=f.read(10000)).length() > 0)
{
do something....
}
In other words, I want to read a potentially large file in 10000 byte
chunks (or some other suitably large chunk size). Since the Python
'file' object implements __next__() only in terms of lines (even,
it seems, for files opened in binary mode) I can't see how to use
the Python for statement in this context.
Am I missing something basic, or is this the canonical way:
with open(filename,"rb") as f:
buf = f.read(10000)
while len(buf) > 0
# do something....
buf = f.read(10000)
