Failed to run file in a submodule

python pyapi/keyword.py

ImportError: No module named dirFoo1.foo1

Set your PYTHONPATH environment variable. For example like this PYTHONPATH=.:.. (for *nix family).

Also you can manually add your current directory (src in your case) to pythonpath:

import os import sys sys.path.insert(0, os.getcwd())

Enable simple default logging

import logging

logging.basicConfig(format='%(asctime)s,%(msecs)d %(levelname)-8s [%(filename)s:%(lineno)d] %(message)s', datefmt='%Y-%m-%d %H:%M:%S', level=logging.INFO)

# 记录下来 行号 文件名:方法名
logging.basicConfig(filename='application.log', level=logging.INFO, format='%(asctime)s - %(levelname)-5s %(lineno)d %(filename)s:%(funcName)s - %(message)s')

logger = logging.getLogger(__name__)

Logging to console and file

import logging

# 定义日志格式
log_format = '%(asctime)s %(levelname)s - [P:%(process)d] - %(filename)s.%(funcName)s:%(lineno)d - %(message)s'
date_format = '%Y-%m-%d %H:%M:%S'

logging.basicConfig(level=logging.INFO, format=log_format, datefmt=date_format)
file_handler = logging.FileHandler('application.log')
file_handler.setLevel(logging.INFO)
file_handler.setFormatter(logging.Formatter(log_format, datefmt=date_format))

logging.getLogger().addHandler(file_handler)

Get current function name

function_name = sys._getframe().f_code.co_name

import sys

def query_database():
    function_name = sys._getframe().f_code.co_name
    logger.info("Start %s()" % function_name)
    start_time = time.time()
    #.....
    logger.info("%s() cost: %s " % (function_name, time.time() - start_time) )

Dynamically replace a method of third-party library.

For example, repace the werobot get_access_token method to use a customized method which stores token in redis, and share the token across processes.

from werobot.client import Client

## 覆盖 Client 类中的 get_access_token 方法，存储 token 信息到 redis
from client_shared import get_shared_access_token

Client.get_access_token = get_shared_access_token

Call a function dynamically by function name

# I have this code:

fields = ['name','email']

def clean_name():
    pass

def clean_email():
    pass

# How can I call clean_name() and clean_email() dynamically?


Solution based on none class and class:

``` python
  # method 1
        function = getattr(sys.modules[__name__], function_name)  # or you can use module name instead of __main__
        return function(text)  # calls my_function and outputs "Hello, world!"
        
  # method 2, mapp function to values in dictionary
  fields = {'name':clean_name,'email':clean_email}

  for key in fields:
    fields[key]()
  
# method 3, class
#  You could even move further and do something like this:

class Cleaner(object):
    def __init__(self, fields):
        self.fields = fields

    def clean(self):
        for f in self.fields:
            getattr(self, 'clean_%s' % f)()

# Then inherit it and declare your clean_<name> methods on an inherited class:

cleaner = Cleaner(['one', 'two'])
cleaner.clean()

Current time and date

week_list = ["星期一","星期二","星期三","星期四","星期五","星期六","星期日"]

def current_time(prompt):
    unix_time = time.time()
    text = datetime.fromtimestamp(unix_time).strftime('%Y-%m-%d %H:%M:%S')
    return "现在的时间是: %s" % text

def current_date(prompt):
    today = date.today()
    text = date.strftime(today, "%Y年%m月%d日")
    return "今天是: %s" % text
    
def current_day(prompt):
    today = datetime.today()
    # 使用strftime()方法将今天的日期格式化为星期几的字符串
    weekday = week_list[today.weekday()]
    return "今天%s" % weekday
