Why doesn't this work?

Question

data = ["John", "Doe", 53.44]
message = "Hello, %s %s. Your balance is $%s."
print(message % data)

It tells me there are not enough arguments for format string to work.

Answer 1

data = ("John", "Doe", 53.44) # tuple
message = "Hello, %s %s. Your balance is $%.2f." # last one is float instead of string
print(message % data)
