Using Python and Streamlit with MS SQL

Sat, 22 Nov 2025 00:00:00 +0000

Create and activate the Python environment
Install Python modules
Install MS SQL
Start coding & Run

Prerequisites

For this project, we used MS SQL, so the operating system is Windows Server 2012. I installed MS SQL Server 2012 Advanced. If your system is Windows 10 or Windows 11, install the latest version of MS SQL Express instead.

Python 3.12
Windows OS
MS SQL Express
Internet

Get started

Create and activate the Python environment

# Create the virtual environment
python -m venv c:\project\event

# Activate it
cd c:\project\event\Scripts
.\activate

# Deactivate it when finished
deactivate

Install Python modules

You can install these modules step by step, or use pip install -r requirement.txt.

Python 批量查询快递单号，并将查询结果填入Excel中

Fri, 08 Dec 2023 00:00:00 +0000

缘由

因为11月份是快递量比较大时候，会有有很多快递单需要查询快递状态；之前是因为单量少，每一个单每一个单去baidu 直接看百度查询到的结果。这两个月由于快递单特别多，于是就打算用Python 结合快递100的API 来查询快递状态

代码

快递100 API

实时查询状态

# coding = utf-8
import hashlib
import json

import requests

class KuaiDi100:
 def __init__(self):
 self.key = '' # TODO 客户授权key
 self.customer = '' # TODO 查询公司编号
 self.url = 'https://poll.kuaidi100.com/poll/query.do' # 请求地址

 def track(self, com, num, phone, ship_from, ship_to):
 """
 物流轨迹实时查询
 :param com: 查询的快递公司的编码，一律用小写字母
 :param num: 查询的快递单号，单号的最大长度是32个字符
 :param phone: 收件人或寄件人的手机号或固话（也可以填写后四位，如果是固话，请不要上传分机号）
 :param ship_from: 出发地城市，省-市-区，非必填，填了有助于提升签收状态的判断的准确率，请尽量提供
 :param ship_to: 目的地城市，省-市-区，非必填，填了有助于提升签收状态的判断的准确率，且到达目的地后会加大监控频率，请尽量提供
 :return: requests.Response.text
 """
 param = {
 'com': com,
 'num': num,
 'phone': phone,
 'from': ship_from,
 'to': ship_to,
 'resultv2': '1', # 添加此字段表示开通行政区域解析功能。0：关闭（默认），1：开通行政区域解析功能，2：开通行政解析功能并且返回出发、目的及当前城市信息
 'show': '0', # 返回数据格式。0：json（默认），1：xml，2：html，3：text
 'order': 'desc' # 返回结果排序方式。desc：降序（默认），asc：升序
 }
 param_str = json.dumps(param) # 转json字符串

 # 签名加密， 用于验证身份， 按param + key + customer 的顺序进行MD5加密（注意加密后字符串要转大写）， 不需要“+”号
 temp_sign = param_str + self.key + self.customer
 md = hashlib.md5()
 md.update(temp_sign.encode())
 sign = md.hexdigest().upper()
 request_data = {'customer': self.customer, 'param': param_str, 'sign': sign}
 return requests.post(self.url, request_data).text # 发送请求

result = KuaiDi100().track('yuantong', 'YT9693083639795', '', '广东省江门市', '广东省深圳市')
print(result)

Coding Practice. Use an IP Guide retrieve your ip information

Sat, 02 Dec 2023 00:00:00 +0000

Intuduction

When we need to check some IP address information , do we have to open the browser, then type the googl domain and copy-paste the IP address?

In this article . I’m goinG to use python with IP GUIDE to check ipaddres information .This much better before.

Let’s started

Install Python

found what version can be match your OS , download it and installl .
https://www.python.org/downloads/

Install requests library

website: https://pypi.org/project/requests/
$ python -m pip install requests

Code

#import requests library
import requests

#get data from ip guide
response = requests.get(f'https://ip.guide/').json()

#function get_ip
def get_ip():
 return response["ip"]

#function get_location
def get_location():
 location_data = {
 "Latitude":response["location"]["latitude"],
 "Longitude" : response["location"]["longitude"],
 "City": response["location"]["city"],
 "Country": response["location"]["country"]
 }
 return location_data

#function get_network
def get_network():
 network_data = {
 "Cidr": response["network"]["cidr"],
 "Host Start" : response["network"]["hosts"]["start"],
 "Host end" : response["network"]["hosts"]["end"]
 }
 return network_data

#dictionary variable
network_data = get_network()
location_data = get_location()
ipaddress = get_ip()

# output information 
print(f"Your internet IPaddress is :{ipaddress}\n and below is this IPaddress other informations\n")

# for loop
for key,value in network_data.items():
 print(f"{key}: {value}")
print(" \n")

for key,value in location_data.items():
 print(f"{key}: {value}")
print(" \n")
