Answer by Devbrat Shukla for How do I check whether a file exists without exceptions?

Use os.path.exists() to check whether file exists or not:

def fileAtLocation(filename,path):    return os.path.exists(path + filename)filename="dummy.txt"path = "/home/ie/SachinSaga/scripts/subscription_unit_reader_file/"if fileAtLocation(filename,path):   print('file found at location..')else:   print('file not found at location..')
