Python range() function
The Python range() function (built-in-function) is used to generate a sequence of numbers. It generates a list of integers from some lower limit (0 by default) up to some upper limit , possibly in increments (steps) of some other number (1 by default). The range() function works a little bit differently between Python 2.x and Python 3.x under the hood, however the concept is the same.
- start - The starting point for the range() to generate numbers.
- stop - It is the point just before range() ends. The range of integers end at stop - 1.
- step (Optional) - integer value which determines the increment between each integer in the sequence.

How to floats with Python's range() function
Unfortunately Python range() function doesn't support the float numbers. i.e. user cannot use floating point number in any of its argument.
If you provide a non-integer stop value, then it raises a TypeError: 'float' object cannot be interpreted as an integer .
However, you can implement an alternate way to get the range of floating numbers .

Concatenation of two range() functions using chain() method
The chain() method takes any number of iterables as arguments and "chains" them together.

Python range() to List
The Python range type represents an immutable sequence of numbers, so it is possible to convert the output of a range() to the Python list.
