I'd like to ask you a question about the Python string formatting decimal pointPlease let me know

>>> a=10

>>> b=20

>>> "a/b is %0.6f"%(a/b)

'a/b' is 0.500,000'

>>> "a/b is %".6f"%(a/b)

'a/b' is 0.500,000'

"a/b is 0.500000" comes out What's the difference between making the input 0.6 and making it 0.6 above?
