Python basic data types12/31/2023 ![]() Bools are either True or False (Capitals Matter!). Str's are any anything surrounded by double quotes ("im a string") or single quotes ('i am also a string').īoolean: In python boolean's are represented by the keyword "bool". String: In python strings are represented by the keyword "str". Floats's are any decimal number (negative or positive). Int's are any whole number (negative or positive).įloat: In python floats are represented by the keyword "float". Integer: In python integers are represented by the keyword "int". In Python there are many different data types but the ones we are going to talk about now are the following: The data type of an object dictates the different things that we can do to it and use it for. Once we've done this I recommend saving your file by hitting CTRL + S or by clicking File > Save As.Ī "Data Type" is simply a classification of information. This should open up what looks like a blank file. Once we've done that we need to click File > New File from the top menu bar. To do this simply find "IDLE" and double-click to run it (you can type IDLE in your windows search bar and it should show up). To get started we need to get to the text-editor built into IDLE. This is great for testing small snippets of code but it's not what we want for right now. In the shell you can type any python code you wish and after hitting enter it will immediately be executed. The shell is what will appear after launching the program. IDLE has two main components, a text-editor and a shell. Luckily for us when we install python it comes with its own editor named "IDLE". Python has a series of data types that define a set of values with characteristics and specific properties, these data types allow us to handle information. Whenever we are writing python code we want to use some sort of a text-editor or IDE (Integrated Development Environment). NumPy Standard Data Types int32, Integer (-2147483648 to 2147483647) int64, Integer (-9223372036854775808 to 9223372036854775807) uint8, Unsigned integer (0. This allows for programs to be written and tested much faster than many other languages. The main advantage python has over other languages is its simplicity. Python is most commonly used for web design but is also capable of making games, performing data analysis, controlling robots, creating GUI's and much more. It is an extremely powerful language that is used in a variety of different applications. Its syntax (words, structure and commands) is very similar to English which allows it to be learned quickly. Python is a very beginner friendly language. Hence, they are mutable objects.Before starting please ensure that you have downloaded and installed python 3.0+ from the python website. It is possible to add, delete, insert, and rearrange items in a list or dictionary. On the other hand, items in a List or Dictionary object can be modified. Numbers, strings, and Tuples are immutable, which means their contents can't be altered after creation. Some of these values can be modified during processing, but contents of others can't be altered once they are created in the memory.
