Data types

Python infers data types of variables. This means that you don't need to write string, boolean, int or others to explicit declarations to work with variables. You can specify the type of a variable using cast for that.

The basics for write a variable and its value is variable name + equals sign + variable value. That will create a new variable and its type will be infered by the value type.

myVariableName = myValue

I'll show you some data types bellow, but you can learn more about other ones on this site

Integer

myInteger = 3 # infered data type

or

myInteger = int(3) # explicitly

Float

myFloat = 3.5 # infered data type

or

myFloat = float(3.5) # explicitly

String

myString = 'Have a nice day!' # infered data type

or

myString = str('Have a nice day!') # explicitly

You can use double quotes " or single quotes ' to delimit the string. When you're using the first one, it'll be easier to write single quotes inside your value string.

myString = "Jhon's house"

Using single quotes everywhere, you should to scape *\* all of the single quotes in the value.

myString = 'Jhon\'s house'

Boolean

myBool = True

or

myBool = bool(True)
