Swipe to start coding

Implementing a function add_user to manage users in a database. If the user exists in users_db, their fields should be updated instead of creating a new entry. If the user is not found, a new user should be added with the provided details.

Define the add_user function with parameters name, age, role (default is "user"), and status (default is "active").
Check if a user with the same name exists in the users_db list.
If the user exists, update their age, role, and status with the values received as arguments in the add_user function.
Return the string "User {name} updated successfully!" after updating the user.
If the user doesn't exist, create a new user (new_user) with the provided details(name, age, role, status).
Add the new user (new_user) to list users_db.
Return the string "User {name} added successfully!" after adding the new user.

Løsning

users_db = []

def add_user(name, age, role="user", status="active"):

# Check if the user already exists

for user in users_db:

if user["name"] == name:

# Update the user if they already exist

user["age"] = age

user["role"] = role

user["status"] = status

return f"User {name} updated successfully!"

# Add a new user if they don't exist

new_user = {

"name": name,

"age": age,

"role": role,

"status": status

}

users_db.append(new_user)

return f"User {name} added successfully!"

# Testing the result

print(add_user("Alice", 30))

print(add_user("Bob", 25, role="admin"))

print(add_user("Alice", 31, status="inactive"))

# Check the list of users

print(users_db)
