objgraph是一个用于定位内存泄露的工具
>>> class Container:
... def point(self, value):
... self.point = value
...
>>> container_one = Container()
>>> container_two = Container()
>>> container_one.point(container_two)
>>> container_two.point(containe1、安装pyenv
brew install pyenv
2、添加环境变量PYENV_ROOT
# 修改 ~/.bash_profile 添加
export PYENV_ROOT=/usr/local/var/pyenv
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi3、安装 python
pyenv install 3.6.2
如果上面安装很慢可以将文件包下载下来，放到 $PYENV_ROOT/cache 目录中（提前创建好）
mkdir -p $PYENV_ROOT/cache
cd $PYENV_RO1.查看orm执行的sql
In [1]: from cost_app.models import AccountInfo
In [2]: print(str(AccountInfo.objects.all().query)) 1、安装
pip install elastisearch
2、连接elasticsearch
from elasticsearch import Elasticsearch
es = Elasticsearch(hosts="192.168.28.25", port=9200, timeout=200)
3、创建索引
from elasticsearch import Elasticsearch
from datetime import datetime
class MyElasticsearch(object):
"""本pip install xlwt # xlwt库负责将数据导入生成Excel表格文件.
pip install xlrd # xlrd库则负责将Excel表格中的数据取出来。
import xlwt
from datetime import datetime
def excel():
wb = xlwt.Workbook()
# 添加一个表
ws = wb.add_sheet('cpsapi.lejunwl.com访问异常ip')
now_time = datetime.now().strftime('pip install mysqlclient
import MySQLdb
conn = MySQLdb.connect(host="localhost",user="root",passwd="12345678",db="pythontest",charset="utf8")
cur = conn.cursor()
# 写入
cur.execute("create table users(id int(2) not null primary key aut1.前端遍历
{% for api in item.important_apis.all%} <-!>注意这里用的是all</-!>
........{{ api.full_url }}
{% endfor %}
2.后端遍历
def item_check(request):
if request.method == 'GET':
item_id = request.GET.get('id')
item = CheckItem.objects.get(id=item_id)
ns1.安装ansible相关模块
pip3 install ansible_runner
pip3 install ansible_inventory
pip3 install ansible_playbook
2、重写官方的回调函数并根据官方的example 封装一个类
ansible2.py
import json
import shutil
from ansible.module_utils.common.collections import ImmutableDict # 用于添加选项。比如: 指定远程用户remote_user=None
from ansible.parsing.d如果执行成功，那么会返回0，表示命令执行成功。
否则，则是执行错误，有以下几种错误分类：
"OS error code 1: Operation not permitted"
"OS error code 2: No such file or directory"
"OS error code 3: No such process"
"OS error code 4: Interrupted system call"
"OS error code获取组或者主机
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
from collections import namedtuple
# 核心类
# 用于读取YAML和JSON格式的文件
from ansible.parsing.dataloader import DataLoader
# 用于存储各类变量信息
from ansible.vars.manager import VariableManager
# 用于导入资产文件
from ansible.inventory.manager import InventoryMa
