Use of { :d } in the print format

#1

there’s line in code where it is written
print( 'marks : " { :d }" ’ . format(self.marks) )

what is :d in the brackets?

can’t we directly write
print( "marks : { } " . format(self.marks) )

hey @muditarya31 ,
this is just a kind printing values with types defined.

its just stating that value to be printed is a decimal .

In the above case it works the same with both line of codes.
But take an example where you want to directly print binary of a decimal number
we can write it as

print("{:b}".format(2))

it output as 10 ( 2 in binary )

I hope this would have resolved your doubt.
