Answer 1

Some Guy Whit A Computer ,

if you need a higher precision as float or double can give, you can use the "Decimal" datatype. to do so, you need to import the decimal module in python. you can find more about it in the documentation:

https://docs.python.org/3.9/library/decimal.html

Answer 2

s = 1
for i in range(int(input())):
print("0."+"3"*s)
s += 1

Answer 4

Unfortunately, most decimal fractions cannot be represented exactly as binary fractions. One consequence of this is that, in general, values entered as decimal floating point values can only be approximated by the binary floating point values that are actually stored by the computer.

Answer 5

Thanks you all

Answer 6

Did you try to start with the smallest one (r += 0.000003) , and end with the biggest (r += 0.3) ?

print(r/(10**(k+1)))
k += 1
