Python 3 Removing All Decimal numbers from float but keep decimal

Question

I wanted to create numbered bullet points.

Decided the way I wanted to do it was

Strip a float of all numbers behind the decimal, but keep the decimal.

Example: 2.0 would be 2. 3.14 would be 3.

Is there way to do it this way? If so what would it look like?

Once again, Thanks in advance.

If you want to stay the `dot` after the number its not possible using `integer`s or `float`s but maybe using `string`s. — Azhy, Jul 25 '18 at 15:40

One way to do so would be to first use int to just obtain the integer part of the float. Then if you just want a number like 3. this is impossible without converting to string since 3. give 3.0. So perhaps convert the integer part to a string then concatenate a period of the form '3.' An example:

In [1]: num = 3.14

In [2]: myint = int(num)

In [3]: myint
Out[3]: 3

In [4]: mystr = str(myint)

In [5]: mystr
Out[5]: '3'

In [6]: mystr += '.'

In [7]: mystr
Out[7]: '3.'

or in one step:

mystr = str(int(num)) + '.'

giving the output of '3.' given the input num = 3.14:

In [12]: mystr
Out[12]: '3.'

str(int(x)) + "."

Converting back to float would add a zero after the decimal, so it has to be left in string.
