# Python Course #2: Data Types

## integers

You probably know about numbers. Numbers are integers like 5, 728, -98, -193 etc. Numbers are data types. A int is a integer/number.

## floats

A float has a decimal point: 54.34 and -76.2. Floats are decimals. Floats are useful for trying to figuring out pi (3.14159265359). It's also useful for exact numbers. If you wanted to express the number between 3 and 4, you would want to write "3.5". Sorry fraction users, fractions are **not** used in python calculation, but you could convert decimals into fractions.

## strings

str are "strings". Strings are words.

123abc is considered a str. As long as a data type has a word/letter, then it would be considered a string. Periods, Commas, Hyphens, Brackets, and etc. are all strings. You use strings all the time to communicate.

## booleans

True and False are the only booleans. True is basically "yes", while False is "no". Booleans are used to answer questions such as *Is 5 more than 2?* if it is, then you would reply "True!", else reply "False".

Booleans are also 0s and 1s. Computers send information using 0s and 1s. In a picture 0 could mean white and 1 could mean black:

0110

1001

0101

except for the 0s and 1s are all in one line:

### That's all for today.

if you hadn't read the last tutorial, go to https://replit.com/talk/learn/PrintingCommenting-Python-Course-1/142824

It is not really in depth though it is good and thank you for your time and effort gone into making this tutorial

thanks

Maybe add a more in depth explanation of how data types are interpreted to a computer. For example booleans are the basis for computers as they can represent 1s and 0s also known as boolean logic.
