storing logger messages in a string

Question

I wanted to store all the intermediate log messages (warn, info, error) to a string in python and finally at the end of program, display everything as a report to the consol

Answer 1

Maybe this example code is enough.
In general, you should post your code so we can see what is going on.
You should also be looking at the actual Python documentation for the logging module while you are following any given tutorial.
https://docs.python.org/2/library/logging.html

The standard Python logging module can log to a file. When you are done logging, you can print the contents of that file to your shell output.

# Do some logging to a file
fname = 'mylog.log'
logging.basicConfig(filename=fname, level=logging.INFO)
logging.info('Started')
logging.info('Finished')

# Print the output
with open(fname, 'r') as f:
    print f.read() # You could also store f.read() to a string
