When do you use {....:3f or 4f or etc.}
this is string formatting specification
see https://docs.python.org/3/library/string...ing-syntax
.2f means dosis is float number and you want it to be displayed with 2 decimal places precision, e.g.>>> dosis = 1/3
>>> dosis
0.3333333333333333
>>> f'{dosis:.2f}'
'0.33'
>>> f'{dosis:.4f}'
'0.3333'
>>>
