Exponents in Python

You can use exponents in Python, without using any modules. Let's see an example. To raise 3 squared, would look like this:

    >>> 3**2
    9

Easy. So when using a single * it's multiplication, when using two ** it's raised.

To get 2 to the power of 3, you would use:

    >>> 2**3
    8

Raise many

To get a lot of exponents, you can use it combined with a for loop:

    >>> for i in range(1,10):
    ...     3**i
    ... 
    3
    9
    27
    81
    243
    729
    2187
    6561
    19683

In these examples I'm using the Python interpreter, you can run it in code too. But then you have to print the output.

    x = 2**3
    print(x)

Explicit output

You can output variables together with text like this:

    for i in range(0,10):
        print("Exponent, 3 to the power of",i,"=",3**i)

This outputs the data in more descriptive terms:

Exponent, 3 to the power of 0 = 1
Exponent, 3 to the power of 1 = 3
Exponent, 3 to the power of 2 = 9
Exponent, 3 to the power of 3 = 27
Exponent, 3 to the power of 4 = 81
Exponent, 3 to the power of 5 = 243
Exponent, 3 to the power of 6 = 729
Exponent, 3 to the power of 7 = 2187
Exponent, 3 to the power of 8 = 6561
Exponent, 3 to the power of 9 = 19683
