String formatting with “{0:d}”.format gives Unknown format code 'd' for object of type 'float'

Question

If I understood the docs correctly, in python 2.6.5 string formatting \"{0:d}\" would do the same as \"%d\" with the String.format() way of formatting strings

Answer 1

That error is signifying that you are passing a float to the format code expecting an integer. Use {0:f} instead. Thus:

"I have {0:f} dollars on me".format(100.113)

will give:

'I have 100.113000 dollars on me'

Answer 2

Yes, you understand correctly. However you are passing float (i.e. 100.113), not int. Either convert it to int: int(100.113) or just pass 100.

Answer 3

delete 'd', since the object type might not be a number as in my case
