How to operate logging logs in python

Today, I will talk to you about how to operate the logging log in python. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Create a new python file named py3_adv_logging.py, and write the operation code in this file:

Advanced use of import logging#logging module # Loggers, Handlers Formatters# sets the logger name of the log logger = logging.getLogger ('Employee') # sets the log level logger.setLevel (logging.INFO) # defines the log formatting output formatter = logging.Formatter ('% (levelname) name) slug% (message) s') # specifies the log processor of the file file_handler = logging.FileHandler ('employee.log') # sets the log formatting file_handler.setFormatter (formatter) for the log processor # add file processor logger.addHandler (file_handler)

# define class class Employee: "A sample Employee class"

Def _ init__ (self, first, last): self.first = first self.last = last

Logger.info ('Created Employee: {}-{}' .format (self.fullname, self.email))

@ property def email (self): return'{}. @ email.com'.format (self.first, self.last)

@ property def fullname (self): return'{} {} '.format (self.first, self.last)

# when we create an object # will automatically record the log information in the # employee.log file emp_1 = Employee ('John',' Smith') emp_2 = Employee ('Corey',' Schafer') emp_3 = Employee ('Jane',' Doe')

The result of running is to generate a file employee.log with the contents of the file:
