• Basic types and their use in Python

The basic types of variables are:

Char: Used to write just one letter. (a)

String: Used to write text. (hello world)

Int: used to assign numbers. (3, 3, 33 , 2223, -1)

Float: Used to assign decimal numbers. (3.33 34343.32 2.2451)

• Calling Python functions

To call a function in  Python, after you define your function you write “exampleoffunction()” , that way python knows that it will have to bring the function.

For example, in this program I defined the function suma, and then I call it writting “suma()”.

1. Python conventions (Zen of Python)

Write in the terminal python, and then “import this”.

1. Install Linux on their own computer

1. Basic output (print) in Python

To print text in python, you must write ‘print (“text text text”)’ and that’s it.

Use of loops with “while”

Using a while in python is simple, very similar to an if. Only write “while (condition):”, and remember to leave a space under the while. and the end of the loop define the variable that will be used in the while.

Use of “else” with a conditional

Using an else in python is very similar to using an if.

Continuing with the program created in Mastery15, If the condition is not true in the if, python will jump to the else. to write and else just put “else :” and then (after leaving a space) write what you want the program to do.

Use of the conditional “if”

To use an if, you’ll have to write “if (‘comparison’):” and then you write the rest. Don’t forget to leave a space for python to know that what you are writting next is part of the conditional.
