I am making a contact Book to store Name, Phone, and Email using entry level Python but need some help.

Here is what I have:

class ContactBook:
def init(self):
self.contacts = {} # Initialize an empty dictionary to store contacts

def add_contact(self, name, phone, email):
    """Add a new contact."""
    if name in self.contacts:
        print(f"Contact '{name}' already exists.")
    else:
        self.contacts[name] = {'Phone': phone, 'Email': email}
        print(f"Contact '{name}' added successfully.")

def remove_contact(self, name):
    """Remove a contact."""
    if name in self.contacts:
        del self.contacts[name]
        print(f"Contact '{name}' removed successfully.")
    else:
        print(f"Contact '{name}' not found.")

def update_contact(self, name, phone=None, email=None):
    """Update an existing contact."""
    if name in self.contacts:
        if phone:
            self.contacts[name]['Phone'] = phone
        if email:
            self.contacts[name]['Email'] = email
        print(f"Contact '{name}' updated successfully.")
    else:
        print(f"Contact '{name}' not found.")

def view_contact(self, name):
    """View details of a contact."""
    if name in self.contacts:
        print(f"Contact '{name}':")
        print(f"  Phone: {self.contacts[name]['Phone']}")
        print(f"  Email: {self.contacts[name]['Email']}")
    else:
        print(f"Contact '{name}' not found.")

def search_contact(self, search_term):
        """Search for a contact by name, phone number, or email address.
        Args:
            search_term (str): The term to search for (name, phone, or email).
        Returns:
            list: A list of matching contacts (if any)."""
        matching_contacts = []
        for name, contact_info in self.contacts.items():
            if search_term.lower() in name.lower():
                matching_contacts.append(name)
            elif search_term.lower() in contact_info['Phone'].lower():
                matching_contacts.append(name)
            elif search_term.lower() in contact_info['Email'].lower():
                matching_contacts.append(name)

        if matching_contacts:
            print(f"Matching contacts for '{search_term}':")
            for contact_name in matching_contacts:
                print(f''  {contact_name}'')
        else:
            print(f"No contacts found for '{search_term}'.")
