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.
In programming the ability to have these values allows us to manage in a very simple way some operations like for example the conditions. [
The IF command is used to construct conditional constructs. The IF construct consists of a condition and a set of instructions within it. If the condition produces a True value, that is, the statements within the construct are verified, otherwise no and execution passes to the next command
The IF-ELSE construct is used to differentiate between operations to be performed when in a condition we want to cover 100% of cases.
In This section, we discover how we can create more complex conditions using Boolean logic through Boolean operators (and, or, and NOT). [
Operator precedence is a very important concept in general programming. In fact the order in which the operators are assessed in the evaluation of an expression (including the conditions) is very important, both in mathematics and in programming itself.
