以下是一个简化的 Python 代码框架,以及如何实现上述功能点的基本思路,可以基于这个框架进一步开发和完善你的小程序。
以下是一个简化的 Python 代码框架,使用了基本的类和函数来模拟上述功能:
python
import pandas as pd
from cryptography.fernet import Fernet
import matplotlib.pyplot as plt
from typing import List, Dict
# 数据加密类
class DataEncryptor:
def __init__(self, key):
self.key = key
def encrypt(self, data):
fernet = Fernet(self.key)
encrypted_data = fernet.encrypt(data.encode())
return encrypted_data
def decrypt(self, encrypted_data):
fernet = Fernet(self.key)
decrypted_data = fernet.decrypt(encrypted_data)
return decrypted_data.decode()
# 账单记录和分类
class BillTracker:
def __init__(self):
self.bills = []
def add_bill(self, amount, category, date):
bill = {
'amount': amount,
'category': category,
'date': date
}
self.bills.append(bill)
def get_category_totals(self):
category_totals = {}
for bill in self.bills:
if bill['category'] in category_totals:
category_totals[bill['category']] += bill['amount']
else:
category_totals[bill['category']] = bill['amount']
return category_totals
# 消费分析报告
class ConsumptionAnalyzer:
def __init__(self, bill_tracker):
self.bill_tracker = bill_tracker
def generate_report(self):
category_totals = self.bill_tracker.get_category_totals()
categories = list(category_totals.keys())
values = list(category_totals.values())
# 生成图表
plt.pie(values, labels=categories, autopct='%1.1f%%')
plt.axis('equal')
plt.show()
# 打印报告
for category, total in category_totals.items():
print(f"{category}: {total}")
# 储蓄目标跟踪
class SavingsTracker:
def __init__(self, initial_amount):
self.current_amount = initial_amount
def add_savings(self, amount):
self.current_amount += amount
def get_progress(self, target_amount):
progress = (self.current_amount / target_amount) * 100
return progress
# 用户自定义设置
class UserSettings:
def __init__(self):
self.encryption_key = None
self.savings_target = None
def set_encryption_key(self, key):
self.encryption_key = key
def set_savings_target(self, target):
self.savings_target = target
# 示例代码逻辑
def main():
# 用户设置
user_settings = UserSettings()
user_settings.set_encryption_key(b'Sixteen byte key')
user_settings.set_savings_target(10000)
# 账单记录
bill_tracker = BillTracker()
bill_tracker.add_bill(500, 'Food', '2023-11-01')
bill_tracker.add_bill(300, 'Entertainment', '2023-11-01')
# 分析和报告
analyzer = ConsumptionAnalyzer(bill_tracker)
analyzer.generate_report()
# 储蓄跟踪
savings_tracker = SavingsTracker(2000)
savings_tracker.add_savings(1000)
progress = savings_tracker.get_progress(user_settings.savings_target)
print(f"Savings progress: {progress:.1f}%")
if __name__ == "__main__":
main()
在这个框架中:
DataEncryptor
类负责数据的加解密。BillTracker
类管理账单的记录和分类。ConsumptionAnalyzer
类生成消费分析报告。SavingsTracker
类跟踪储蓄目标进度。UserSettings
类允许用户自定义设置,如加密密钥和储蓄目标。
这只是一个基础的框架,需要根据实际需求添加更多的功能和安全措施,比如用户身份验证、数据库后端支持、更复杂的报告生成、前端界面等等。此外,要确保加解密密钥的安全存储和传输,可能还需要考虑密钥的备份和恢复机制。对于图表和报告的生成,可以使用 matplotlib 和 pandas 等库来生成静态图表,或者使用更高级的库如 Dash 或 Streamlit 来生成交互式报告。
