### Python Native Payment Integration Demo

Source: https://www.yuque.com/leshua-jhzf/qrcode_pay/ice1rg?language=en-us

Demonstrates MD5 signature generation and merchant order ID formatting for the payment interface.

```python
import hashlib
import requests
import datetime
import random
import string
import json
'''
定义签名函数
'''
def sign_MD5(data):
unsigned_items = sorted(data.items(), key=lambda d: d[0], reverse=False)
unsigned_string = "&".join("{0}={1}".format(k, v) for k, v in unsigned_items)+"&key="+key
print(unsigned_string)
h = hashlib.md5()
h.update(unsigned_string.encode(encoding="utf-8"))
return h.hexdigest().upper()
'''
定义商户订单号规则，服务商可根据自身规则自由定义
'''
def mer_order_id():
now = datetime.datetime.now()
order_id0 = "T" + now.strftime("%Y-%m-%d-%H-%M-%S").replace("-", "")
ran_str = ''.join(random.sample(string.ascii_letters + string.digits, 8))
```

### Python Refund Transaction Demo

Source: https://www.yuque.com/leshua-jhzf/qrcode_pay/kegaff?language=en-us

Provides a reference implementation for MD5 signature generation and merchant order ID creation. Ensure the 'key' variable is defined before calling the signing function.

```python
import hashlib
import requests
import datetime
import random
import string
import json
'''
定义签名函数
'''
def sign_MD5(data):
unsigned_items = sorted(data.items(), key=lambda d: d[0], reverse=False)
unsigned_string = "&".join("{0}={1}".format(k, v) for k, v in unsigned_items)+"&key="+key
print(unsigned_string)
h = hashlib.md5()
h.update(unsigned_string.encode(encoding="utf-8"))
return h.hexdigest().upper()
'''
定义商户订单号规则，服务商可根据自身规则自由定义
'''
def mer_order_id():
now = datetime.datetime.now()
order_id0 = "T" + now.strftime("%Y-%m-%d-%H-%M-%S").replace("-", "")
ran_str = ''.join(random.sample(string.ascii_letters + string.digits, 8))
order_id=order_id0 + ran_str
```
