First declare variables
This cant be printed, because the if only executes the action when its true.
And now, a if that can be printed because its true.
You can add variables, more conditions.

Welcome to another post, and another loop.
In this case we explain the FOR loop. The for loop is used for the same things as the While Loop, but the for loop is for finite loops.
You can use Lists.
If you put, for example the print (“A value”) into the loop, the words “A value” can be printed with every number.
Range function.
If you put a third number in the (), this number activates a function that says steps of 2 in the range.
And you can use slices (strings) for the for loops.

The while loop executes a function when this remains true.
Sum.
Argument END.
An Infinite loop.

In this post we have an introduction to strings of python 3.
First, the strings can be enclosed in single quotes (‘ ‘) or doble quotes (” “).
You can put \ to scape single quote or put instead double qoutes ” “
The print () function
\n Character
If you dont like to expect a new line, you can put letter r before the quotes.
Operator \t
If you want to span in multiple lines , you can put triple quotes( ¨¨¨ ¨¨¨)
Properties of the strings.
Indexed
Slicing
Strings learned.
And its the end.

Using python 3 as a calculator
I can use python 3 as a calculator using the interpreter of python, you can do the basic math functions.
The integer numbers ( 23 , 45, 4) have type int , and the others numbers with a fractional part ( 2.5 , 4.34, 3.141592653….) have type float
The division (/) always returns a float number, to do a division to get a type int number you need to put // instead of / , and to calculate the remainder use the %.
In python is possible to use the ** operator to calculate powers, 2**2 is equal to write 2² (At a real calculator).
You can use the equal sign = to assign a value to a variable, if you dont assing a variable, you cant use, and you accredit an error.
In the interactive mode the last printed expression is assigned to the variable _
And, you can round the number if you put the function round(AValuue,Numberofdecimals)
And now, a gif of a taco.
