formatting float like int for whole values

[Skaperen]

i know i have seen this before but now that i have a use case, i can't find it.

Output:
>>> foo(3.25)
'3.25'
>>> foo(4.0)
'4'
>>> 

i want to find what works like foo() in this fake example.

i thought i had seen it as a single function. i want to do this in an f-string. i want to keep it simple. maybe it was something i had coded a long time ago like answer #3 in that link.

Something like this perhaps.

def foo (floating_point_number) :
	integer = int (floating_point_number)
	if integer == floating_point_number :
		return integer
	return floating_point_number

print (f'{foo (3.25)}, {foo (4.0)}')

[Skaperen]

close to that. while str() isn't exactly necessary, that was what i had in mind ... that foo() did the formatting.

def foo (floating_point_number) :
    integer = int (floating_point_number)
    if integer == floating_point_number :
        return str(integer)
    return str(floating_point_number)

print (f'{foo (3.25)}, {foo (4.0)}')

Do you mean like this?

def foo (floating_point_number) :
	integer = int (floating_point_number)
	if integer == floating_point_number :
		print (integer)
	else :
		print (floating_point_number)

foo (3.25)
foo (4.0) 

[Skaperen]

not to print in the function since i may want 2 or more on the same line. i may or may not need a str returned.

You said that you want this:

Output:
>>> foo(3.25)
'3.25'
>>> foo(4.0)
'4'
>>> 

and I gave you this:

Output:
>>> def foo (floating_point_number) :
...     integer = int (floating_point_number)
...     if integer == floating_point_number :
...             return integer
...     return floating_point_number
... 
>>> foo (3.25)
3.25
>>> foo (4.0)
4
>>> 

The only difference I see is the quotation marks. Is that what your looking for? If not, can you explain exactly what the difference is?

The difference is return a string, not a number. I think Skaperen wants something that returns the shortest string that accurately represents the value of a number.
