  • two.

  • The types of numbers available in Python depend on which version you are using.

  • If you're using version, too, There are four types of numbers If you're using version three, there are three types of numbers If you're using version for your living in the future, and I hope it's amazing our goal today.

  • Learn about the types of numbers in Python version, too.

  • First, start the Python Interpreter.

  • If you see version three, be sure to watch our video on numbers for version three.

  • This video is for people using version, too, and some of the examples will cause an error if you use Python three in Python version, too.

  • There are four types of numbers in CE Long's floats and complex numbers.

  • Two of these types are for whole numbers in CE, which is short for integer and longs.

  • Which one you use depends on how large the whole number is.

  • Most of the time you'll use in CE, but if you're number gets too large, python will automatically switched the longs for you.

  • Notice the hashtag.

  • This is how you write comments and python.

  • Everything after a hashtag is a comment and is ignored by the interpreter.

  • Let's assign the number 28 to the variable, eh?

  • You can see what data type this is by using the type function.

  • A is an end, not along.

  • If you ever need to see the value of a, just type it on press enter.

  • This will print the number, and if you love typing, you can explicitly print it.

  • Insulate you store whole numbers up to a limit to find out the limit.

  • First, import the cyst module and then check the max in property.

  • We'll talk all about imports and module soon.

  • For now, just remember that import cysts brings in a library of system functions.

  • Let's create an interviewer.

  • Be with this maximum value.

  • You can see that it's an ent, but watch what happens if we create the next hole number.

  • We'll call it.

  • See.

  • It creates a long.

  • You can also tell this is a long by displaying its value.

  • See the L at the end.

  • This is how Python tells you the number is a long and not an end.

  • By the way, if you print, see the letter l will not display.

  • This is because printing displays more human readable values.

  • Luckily, you do not have to worry too much about ends and longs.

  • If you're integer gets too large pythons, which is over two lungs.

  • You don't have to worry about integer, overflow and python for the curious.

  • The smallest intern Python version two is equal to mine assist dot maxim to minus one.

  • You can verify this is an end by checking its type or by displaying its value and observing there is no el at the end.

  • If you subtract one from this whole number, then you will see that Python uses along when creating a whole number.

  • You can specify if you'd like to use along to do so.

  • Put a letter L.

  • A.

  • The end of your number.

  • But given pythons automatic handling of Instant Long's, this isn't something you really need to worry about.

  • The third type of number and Python version two is floats.

  • This is how decimal values are stored.

  • To make a float, just type in a number that has a decimal point.

  • We'll use the famous number E, which is approximately 2.7 18 28 18 28 to confirm that this is a float look at its type.

  • The fourth and final type of number, and Python version two is complex numbers.

  • Ah, complex number has a real part on an imaginary part.

  • The mathematical symbol for the complex numbers is a capital C with an extra stroke, while the mathematical symbol for the square root of minus one is I.

  • Many engineers will use the letter J, and this is with Python uses.

  • So to create a conflicts number, just type in the real part, and then the imaginary part, followed by the letter J.

  • You can confirm that this is a complex number.

  • By checking its type you can display.

  • It's really part by displaying the real property, and you can access the imaginary part through the property.

  • Named I.

  • M.

  • A G python automatically uses floats for the real and imaginary parts.

  • Now that you know about its Long's floats and complex numbers, you are ready to tackle arithmetic.

  • Just remember, I is called J Longs and in L.

  • A.

  • And the only thing that can overflow with your drink do you?
