Error converting phone_number to integer: invalid literal for int() with base 10: ''

Question

I'm trying to do the following: The script takes a line from the file, splits it, and then the phone number should be set as a variable for the asterisk dialplan.

File line looks like:

Doe,John,Adam,123456789

But I get an error:

Error converting phone_number to integer: invalid literal for int() with base 10: ''

At the same time, as I understand it, the variable is set, because if I print it, it exists.

phone: 123456789

Tell me, please, what is the error?

with open(file_path, 'r') as file:
    i = 0  
    for line in file:
        
        parts = line.strip().split(',')

        # Ensure that there are enough parts in the line
        if len(parts) >= 4:
            surname, name, lastname, phone_number = parts[:4]

            # Check if phone_number is not empty before conversion
            if phone_number.strip():  # Check if the stripped value is not empty
                try:
                    phone_number = int(phone_number)
                    agi.set_variable('PHONE_NUMBER', f"{phone_number}")
                except ValueError as e:
                    print(f"Error converting phone_number to integer: {e}")
                except Exception as e:
                    print(f"Error setting PHONE_NUMBER: {e}")
            else:
                print(f"Empty phone_number encountered on line {i + 1}, skipping...")
        else:
            print(f"Invalid line format on line {i + 1}: {line.strip()}")

        print(f"phone: {phone_number}")

Update1:

If I remove the conversion to integer, I get this error:

        COMMAND: SET VARIABLE "PHONE_NUMBER" "123456789"
    SET VARIABLE "PHONE_NUMBER" "123456789"
    
        RESULT_LINE:
    Error setting PHONE_NUMBER: invalid literal for int() with base 10: 
''
phone: 123456789

Updated code

with open(file_path, 'r') as file:
    for line in file:
        parts = line.strip().split(',')

        # Ensure that there are enough parts in the line
        if len(parts) >= 4:
            surname, name, lastname, phone_number = parts[:4]

            # Check if phone_number is not empty before conversion
            if phone_number.strip():  # Check if the stripped value is not empty
                try:
                    agi.set_variable('PHONE_NUMBER', phone_number.strip())
                except Exception as e:
                    print(f"Error setting PHONE_NUMBER: {e}")
            else:
                print(f"Empty phone_number encountered on line {i + 1}, skipping...")
        else:
            print(f"Invalid line format on line {i + 1}: {line.strip()}")

        print(f"name: {phone_number}")

Update2 Code:

# Check if phone_number is not empty before conversion
            if len(phone_number) > 0:  # Check if the stripped value is not empty
                try:
                    agi.set_variable('PHONE_NUMBER', phone_number.strip())
                except Exception as e:
                    print(f"Error setting PHONE_NUMBER: {e}")
            else:
                print(f"Empty phone_number encountered on line {i + 1}, skipping...")
        else:
            print(f"Invalid line format on line {i + 1}: {line.strip()}")

Error:

    COMMAND: SET VARIABLE "PHONE_NUMBER" "123456789"
SET VARIABLE "PHONE_NUMBER" "123456789"

    RESULT_LINE:
Error setting PHONE_NUMBER: invalid literal for int() with base 10: ''

As I can see from your error message, that empty string is passed to your int() function.

Check your file and your code again.

phone_number.strip()

is being evaluated as True (May be due Python version).

Try to use ,

len(phone_number) > 0
