Python x =1# assign variable x the value 1y = x +5# assign variable y the value of x plus 5z = y# assign variable z the value of y These examples assign numbers to variables, but numbers are just one of several data types Python supports. Notice there's no type declared for the...
Variables can store data of different types, and different types can do different things. Python has the following data types built-in by default, in these categories: Text Type:str Numeric Types:int,float,complex Sequence Types:list,tuple,range ...
