The floats, or floating numbers, are the decimal numbers, that is, those that have the comma (0.24,-3.1423333). These numbers can be defined directly by writing the number with the comma, or by using operators that generate decimal numbers such as Integer divisions.

Sometimes in some algorithms you need to know in the operations of division, not the result, but the quotient values and remainder. The remainder operation is often also called module (11 Module 3)

In Python You can use text and you can do it using strings, or strings. You can define a string using both the single and the double quotation mark.

Often when running a program, you must return some text strings (output) to the console. We have already seen that to correctly report a string or variable you use the function print ().

Perhaps the most used operation on strings is the concatenation of two or more strings. That is, it is often necessary to combine more strings to form longer sentences.

It often happens (even much more than we realize) that in the lines of code to perform operations between values of different types. We've already seen it between integers and floats. In fact, the integers were implicitly converted to float by the interpreter and then the operation was performed. In This case we talk about implicit conversions.

The variables are practically indispensable in programming and serve to store values in order to be used later.

There are some operators that allow you to write numeric expressions in a more contracted form using with only one operator both the operation and the assignment.

An IDLE is a text editor that allows you to do the programming, that is the writing of the programs in Python in a simple and fast. In fact from the same editor, you can create a new. py file, write the code, run the program, fix the errors, and save the program, to reuse it at a later time

Each element of the list array is copied into a temporary variable called item, on which you will work within the for loop by writing a series of commands in the indentation. No need for counters, no need to know how long the list is.
