how to get around "Single '}' encountered in format string" when using .format and formatting in printing

Question

I am currently trying to print a tabulated format (using left alignment and padding) for headings in a table however I keep getting the following error.

ValueError: Single '}' encountered in format string 

Here's the line:

print("{0}:<15}{1}:<15}{2}:<8}".format("1", "2", "3")) 

Required output is something along the lines of:

1              2              3         

I've tried duplicating the { } as advised here but received no luck.

I am probably missing something incredibly obvious however after staring at it for ages, I cannot see it. After all, what's the harm in asking?

Thanks

Use }}:

>>> "{0}:<15}}{1}:<15}}{2}:<8}}".format("1", "2", "3") '1:<15}2:<15}3:<8}'
