在Python中通過(guò)定義個(gè)類或者系列的函數(shù)來(lái)封裝我司的邏輯。這種封裝使得代碼更加模塊化，易于理解和維護(hù)定義個(gè)Wallet類，它有生成密鑰對(duì)、存儲(chǔ)和恢復(fù)私鑰、發(fā)送和接收貨幣等方法。

```python

from Crypto.PublicKey import RSA

class Wallet:

def __init__(self):

self.private_key = RSA.generate()

self.public_key = self.private_key.publickey()

def get_public_key(self):

return self.public_key.exportKey()

def sign_message(self, message):

signature = self.private_key.sign(message.encode('utf-'), None)

return basebencode(signature).decode('utf-')

def verify_signature(self, message, signature):

try:

self.public_key.verify(basebdecode(signature), message.encode('utf-'))

return True

except ValueError:

return False

```

關(guān)于特許、肥料、材料處理等領(lǐng)域，在Python中通過(guò)封裝函數(shù)來(lái)簡(jiǎn)化復(fù)雜的操作定義個(gè)Fertilizer類，它有計(jì)算最佳施肥量、記錄施肥歷史等功能。
