Python是一種強大的編程語言，使得為公司和組織打造一款客戶關系管理(CRM)系統變得更加容易。我們在這里提供了一份Python編寫的簡單的CRM源代碼，支持以下功能：

• 創建新客戶
• 查找客戶
• 更新客戶信息
• 刪除客戶

import csv
class Customer:
def __init__(self, fname, lname, email, company):
self.fname = fname
self.lname = lname
self.email = email
self.company = company
class CRM:
def __init__(self):
self.customers = []
def add_customer(self, customer):
self.customers.append(customer)
self.save_customers()
def find_customer(self, email):
for customer in self.customers:
if customer.email == email:
return customer
return None
def update_customer(self, email, new_customer):
found_customer = self.find_customer(email)
if found_customer:
found_customer.fname = new_customer.fname
found_customer.lname = new_customer.lname
found_customer.email = new_customer.email
found_customer.company = new_customer.company
self.save_customers()
return True
else:
return False
def delete_customer(self, email):
found_customer = self.find_customer(email)
if found_customer:
self.customers.remove(found_customer)
self.save_customers()
return True
else:
return False
def save_customers(self):
with open('customers.csv', mode='w', newline='') as f:
writer = csv.writer(f)
writer.writerow(['First Name', 'Last Name', 'Email', 'Company'])
for customer in self.customers:
writer.writerow([customer.fname, customer.lname, customer.email, customer.company])

我們建立了一個Customer類來維護每個客戶的信息。CRM類維護所有客戶，并存儲在名為"customers.csv"的CSV文件中。add_customer函數將新客戶添加到列表中，并使用save_customers方法將其保存到文件中。find_customer使用電子郵件地址作為參數并返回包含該地址的客戶。update_customer函數更新該客戶的信息。delete_customer函數使用電子郵件查詢和刪除客戶。所有更改也將保存到CSV文件中。

這只是一個簡單的例子，可以根據需要對其進行更改和擴展，以創建更為全面的CRM系統。
