While Learning Python, we do Print to screen but eventually graduate to printing to output files... However most times all errors are not resolved in the code... In such cases the code aborts after running some 10 20 loops or say 80% of the code and then aborts.. However during this time the data that is printed to the file is lost as the file.close() is not executed.
In Python is there a way in which we can save the WIP file. I want to do this without closing and reopening the file once again multiple times in append modes. This will help in Debugging and also not losing the data that has been accumulated before the error was occurred.
After searching i did not find something like this .... if someone has or can give any ideas how to make a module for this that will be great... What we need is a generic catchall... in case of any error.. execute the catchall code to close the file and then exit from Python.
On the documentation of File objects : https://docs.python.org/2/library/stdtypes.html?highlight=flush#file.flush
Use the flush
function. There is also a note on the doc with os.fsync
function to be sure the data are written on the disc.
