Given that we have already acquired an understanding of the `int()` operation, it is unnecessary to reiterate the same information. The `float()` function serves a similar purpose, with the distinction of converting data into the floating-point data type.Look at this simple example:😁

variable1 = 56
variable2 = "98.7"
variable3 = "5e4"

print(float(variable1))
print(float(variable2))
print(float(variable3))

It seems to me that one fascinating feature of the `float()` function should be noted. Not only can we represent regular numbers, but we can also represent concepts like **infinity** and **Not a Number (NaN)**.

import unittest

class TestUserCode(unittest.TestCase):
    def test_true(self):
        self._testMethodName = "pass"
        self.assertTrue(True, "pass")

if __name__ == '__main__':
    unittest.main()

This course is going to help you dive deeper into data types and try to work with them. Here you will learn basic operations and all ins and outs of numbers, boolean data type, and strings. This course consists of a lot of practical tasks after which you will become a skillful programmer.

Numeric data types are crucial in Python, so it is important to start with them. Here you will work with simple math operations and find out the purposes of learning different types of numerical data.

The main goal of this section is to clarify the boolean data types; it's a sub type of numeric data, but indeed it is more challenging. Since it is always better to excel in the more difficult topics, this section is a valuable part of your curriculum.

Strings are a way for us to implement your phrases in Python, that is, to give instructions to users who are the target audience of your program. Indeed, it is always better to be able to work with strings because they should be used in your code. You'll understand why soon.

This chapter consists of practical tasks that combine all the examined topics together with a bit of theory.
