Python: What does a dot before an integer mean?

I was reading some Python code:

math.ceil(.1) + math.floor(.1)

and have encountered the following notation - .1.

Could someone explain what does it mean?

Thanks in advance.

The integer is a float (decimal) value

>>> .1
0.1
>>> 1
1

As Shashank V's answer notes, one can can check the type of an object by calling type() on it!

>>> type(.1)
<class 'float'>
>>> a = .1
>>> type(a)
<class 'float'>

It's a float. .1 represent the decimal value 0.1

>>> type(.1)
<class 'float'>

.1 is a float, it's equivalent to 0.1
