Вивчайте Managing Customer Data with Python

Managing customer data is a core challenge for startups. As your business grows, keeping track of customer names, emails, and signup dates can quickly become overwhelming if you rely on manual methods like spreadsheets or handwritten notes. Manual management often leads to errors, lost information, and wasted time. Python offers a simple, reliable way to structure and access customer data, allowing you to organize information efficiently and automate repetitive tasks such as searching for a customer or updating their details.


              123456789101112131415161718
            
# Creating a list of customer dictionaries
customers = [
    {"name": "Alice Smith", "email": "alice@example.com", "signup_date": "2024-05-01"},
    {"name": "Bob Johnson", "email": "bob@example.com", "signup_date": "2024-05-03"}
]

# Adding a new customer
new_customer = {"name": "Charlie Lee", "email": "charlie@example.com", "signup_date": "2024-06-10"}
customers.append(new_customer)

# Updating a customer's email
for customer in customers:
    if customer["name"] == "Alice Smith":
        customer["email"] = "alice.smith@startup.com"

# Printing all customer records
for customer in customers:
    print(customer)

In Python, you can use a combination of lists and dictionaries to manage customer information efficiently. Each customer is represented as a dictionary, where keys like "name", "email", and "signup_date" store the relevant details. All customer dictionaries are stored in a list, which makes it easy to add new customers, update existing ones, or remove those who are no longer active. This structure allows you to quickly retrieve any customer's information by looping through the list and checking dictionary values, making your data both organized and accessible.


              12345678910
            
# Searching for a customer by email and updating their information
search_email = "bob@example.com"
for customer in customers:
    if customer["email"] == search_email:
        customer["name"] = "Bob J. Johnson"  # Update the name
        customer["signup_date"] = "2024-06-15"  # Update the signup date

# Print the updated customer list
for customer in customers:
    print(customer)
