Template for Python programs. Creating logfiles, standard modules to load, opening files, user configuration.

Code for mailing is on this wiki too.

ToDO:

  • Parsing commandline options
#!/usr/bin/env python

def usage():
    print ("Usage: "+__file__)
    print("Template for python programs")
    version = 'R1A, 20181010, Initial release'
    print("Version: "+version)
    sys.exit(1)

warning = 'If you need to modify these variables anywhere else you have to declare it global there'
filespec =  '*.*'
logfile2name = '<apath>_timestamp.txt'

# END USER CONFIGURABLE ITEMS, DO NOT CHANGE ANYTHING BELOW THIS LINE

import os

timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")

logfile2name = logfile2name.replace('timestamp',timestamp)

def main():

    openlog(<apath>)
    logging.info("This is in the logfile with generated name")
    openfile(filespec)

    for filename in filelist:
        if os.path.isfile(filename):
            with open (filename,"r") as file:
                for line in file:
                    #remove newline characters

    logging.info(logfilename+" open.")
    return(logfilename)


main()

Logging suggestion to test:

def logfunc(logFile):  
    logging.basicConfig(format = '%(asctime)s %(filename)25s %(levelname)6s : %(message)s' , level=logging.INFO)  
    log = logging.getLogger()  
    fh = logging.FileHandler(logFile)  
    formatter = logging.Formatter('%(asctime)s %(filename)25s %(levelname)6s : %(message)s')  
    fh.setFormatter(formatter)  
    log.addHandler(fh)  
    return log
