Python String Formatting - Type Error - Not enough arguments for format string

Question

So what's wrong with this string? I'm not able to figure out why it says there's not enough arguments for format string. I'm new to Python and just figuring things out.

Edit: This is not the same as the other question suggested. The other is trying to do some crazy array stuff that I am not even getting into. I just need to understand the basic concept of tuples and how string formatting works.

    data = ["John", 23, "United States", "United Kingdom"]
    format_string = "Your name is %s and you are %s years old. You were born in %s and are now living in %s."
    print(format_string %data)

Is it because I do not have enought " strings" inside? How do I have a single list with strings and numbers? For example, a JSON list.

Answer 1

If you pass the list in as a tuple, it should work just fine.

data = ["John", 23, "United States", "United Kingdom"]
format_string = "Your name is %s and you are %s years old. You were born in %s and are now living in %s."
print(format_string % tuple(data))

Answer 2

The right operand of str.__mod__ must either be a tuple or a single value. Since it is not a tuple it is being interpreted as a single value whereas the format string requires a 4-tuple. Either convert data to a tuple or make it a tuple in the first place.
