Integers

So, integers are numbers that do not contain a fractional part. These numbers can be both positive and negative (for example 10, -7 both of these numbers are integers). Let's take a look at the example below.

python
Input:
# Creating integers
x = 7
y = -10
print(f'It's a positive integer: {x}')
print(f'It's a negative integer: {y}')

Output:
It's a positive integer: 7
It's a negative integer: -10

Sometimes you have to check the type of some variables. In python, for it there is an useful function called type(). Let's look at an example of how this function works.

python
Input:
# Creating integers
x = 7
y = -10
print(f'The type of x is {type(x)}')
print(f'The type of y is {type(y)}')

Output:
The type of x is <class 'int'>
The type of y is <class 'int'>

It's time to practice!

Create three variables: a, b, c with the following values: 100, -5, -12350 and check the types of them.

Soluzione

a = 100
b = -5
c = -12350

print(f'It`s a: {a}, the type of a is {type(a)}')
print(f'It`s b: {b}, the type of b is {type(b)}')
print(f'It`s c: {c}, the type of c is {type(c)}')

Tutto è chiaro?

Come possiamo migliorarlo?
