Nested loops ¿what are they? A nested loop is a loop within a loop, an inner loop within the body of an outer one. Is possible to realize this with all the different types of loops, with for´s, here is the basic structure:
also with while’s
with if else, and also combining them.
Here is one example of what you can do with nested loops:

The flowchart of a for is like it follows:
This is the basic structure:
val is a certain value or ‘conditional’
Here is one example

In this post I´ll explain the missing loops, those are: elif, while and for. So let´s get started.
This is the flowchart of an elif
this is how it works
and here is one example

Have you ever tried to bake in the microwave? Not? It is very very simple and is something you should try for two reasons:
That´s it, prove it. Here I leave some examples of the recipes you can make with this method
This is the videos it contains:

Check out the post I worked out with Merino
If statement:
The If statement is a conditional statement and works like this. If a value is true then the instruction stop and the code continues, but if the value is false, the code read the next line on the IF.
The syntaxis is like this:
if expression:
<body>
else:
<body>
Here is an example:
For more details about IF and ELSE you can go to here and here. And also check this blog for more loops wohoo.

Loops are very used in daily life, and I´m not talking about food, i´m talking about programming. But you may ask what is a loop. A loop according to the Merriam Webster is “a series of instructions (as for a computer) that is repeated until a terminating condition is reached”.
Loops depend of a condition, this is a boolean, a boolean is a value that can be either false or true, for more information of Basic Operators, you can go here
In python we have two types of loops and one conditional:
Now…what is the structure of a loop? It is the following
And…what about the ‘if/else’ conditional? Is this
In the following posts Rodrigo Merino and I will explain you more about this

This is one of my shortest posts since this is more of self discover.
Libraries are a very useful topic, they are dictionaries that are already made and that you just invoke them, yep…invoke, you just say ‘import library_name’ and ready, you use it as normal.
Here is the link to all the libraries that python has:

The concept of a function is one of the most important ones in mathematics. A common usage of functions in computer languages is to implement mathematical functions. Such a function is computing one or more results, which are entirely determined by the parameters passed to it.
In the most general sense, a function is a structuring element in programming languages to group a set of statements so they can be utilized more than once in a program. The only way to accomplish this without functions would be to reuse code by copying it and adapt it to its different context. Using functions usually enhances the comprehensibility and quality of the program. It also lowers the cost for development and maintenance of the software.
Functions are known under various names in programming languages, e.g. as subroutines, routines, procedures, methods, or subprograms.
A function in Python is defined by a def statement. The general syntax looks like this:
def function-name(Parameter list):
statements, i.e. the function body
The parameter list consists of none or more parameters. Parameters are called arguments, if the function is called. The function body consists of indented statements. The function body gets executed every time the function is called.
Parameter can be mandatory or optional. The optional parameters (zero or more) must follow the mandatory parameters.
Function bodies can contain one or more return statement. They can be situated anywhere in the function body. A return statement ends the execution of the function call and “returns” the result, i.e. the value of the expression following the return keyword, to the caller. If the return statement is without an expression, the special value None is returned. If there is no return statement in the function code, the function ends, when the control flow reaches the

How can I make inputs? Its Easy peasy dude.
Inputs themselves are a function and you only need to put ‘input()’ and the program will stop in this line and don´t continue without receiving a string input, this is text.
Here is an example:
