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.
The WHILE construct likewise expects to always evaluate a condition and if it is checked (True) a series of operations are performed, but at the end of these, instead of restoring control to the program flow and exiting the construct, the Initial condition is evaluated again.
In the Python language, lists are a type of object. This particular type of object is used to store a series of values in an indexed sequence.
Now that we have seen how to create lists, we see in this section how to apply on them some operations that will prove very useful in programming in Python.
