I have written a several Python scripts to collect data from external
sources (an email account and an sftp site).
In development I run the scripts from IDLE or the command line and can
view
the output of various print statements in the scripts which helps me to
monitor progress and confirm correct operation.
However, in production I will be running the scripts via Cron.
Is there a recommended/ elegant way to collect this output on the fly
for
later review/ processing.
From the python documentation of the print function:
"""
print([object, ...], *, sep=' ', end='\n', file=sys.stdout)
Print object(s) to the stream file, separated by sep and followed by
end. sep, end and file, if present, must be given as keyword arguments.
All non-keyword arguments are converted to strings like str() does
and written to the stream, separated by sep and followed by end. Both
sep and end must be strings; they can also be None, which means to use
the default values. If no object is given, print() will just write end.
The file argument must be an object with a write(string) method; if
it is not present or None, sys.stdout will be used.
"""
The following might work:
with open("progress.txt", "a") as outf:
print("what ever you used to print", file=outf)
Previously I have written bash scripts simply redirecting the standard
output to a text file and emailed this back to myself but I would like
to
do this directly within Python rather than having to wrap the Python
script
in a bash script.
Thanks, Leo.
