#Tutorial Jam

@elipie's jam p i n g

Here is a basic tutorial for Python, for beginners!

Table of Contents:

1. The developer of python

2. Comments/Hashtags

3. Print and input statements

  • f' strings

4. If, Elif, Else statements

5. Common Modules

1. Developer of Python

It was created in the late 1980s by Guido van Rossum in the Netherlands. It was made as a successor to the ABC language, capable interfacing with the Ameoba operating system. It's name is python because when he was thinking about Python, he was also reading, 'Monty Python's Flying Circus'. Guido van Rossum thought that the langauge would need a short, unique name, so he chose Python.

2. Comments/Hastags

Comments are side notes you can write in python. They can be used, as I said before:

  • sidenotes
  • instructions or steps
  • etc.

How to write comments:

The output is nothing because:

  1. It is a comment and comments are invisible to the computer
  2. Comments are not printed in Python

So just to make sure, hastags are used to make comments. And remember, comments are ignored by the computer.

3. Print and Input statements

1. Print Statements

Print statements, printed as print, are statements used to print sentences or words. So for example:

The output would be:

So you can see that the print statement is used to print words or sentences.

2. Input Statements

Input statements, printed as input, are statements used to 'ask'. For example:

The output would be:

However, with inputs, you can write in them. You can also 'name' the input. Like this:

You could respond by doing this:

So pretty much, inputs are used to make a value that you can make later.

Then you could add a if statement, but lets discuss that later.

3. f strings

f strings, printed as f(before a qoutation), is used to print or input a value already used. So what I mean is, say I put an f string on a print statement. Like this:

The output right now, is nothing. You didn't print anything. But say you add this:

It would work, only if the name was named. In other words, say you had a input before and you did this to it:

Then the f string would work. Say for the input, you put in your name. Then when the print statement would print:

Another way you could do this is with commas. This won't use an f string either. They are also simaler. So how you would print it is like this:

The output would be the same as well! The commas seperate the 2 strings and they add the name inside. But JBYT27, why not a plus sign? Well, this question you would have to ask Guido van Rossum, but I guess I can answer it a bit. It's really the python syntax. The syntax was made that so when you did a plus sign, not a comma, it would give you an error.

Really, the only time you would use this is to give back your name, or to find if one value was equal to each other, which we'll learn in a sec.

4. If, Elif, Else Statements

1. If Statements

If statements, printed as if, are literally as they are called, if sentences. They see if a sentence equals or is something to an object, it creates an effect. You could think an if statement as a cause and effect. An example of a if statement is:

The output could be:

However, say it isn't JBYT27. This is where the else, elif, try, and except statements comes in!

2. Elif Statements

Elif statements, printed as elif are pretty much if statements. It's just that the word else and if are combined. So say you wanted to add more if statements. Then you would do this:

It's just adding more if statements, just adding a else to it!

3. Else Statements

Else statments, printed as else, are like if and elif statements. They are used to tell the computer that if something is not that and it's not that, go to this other result. You can use it like this (following up from the other upper code):

5. Common Modules

Common modules include:

  • os
  • time
  • math
  • sys
  • replit
  • turtle
  • tkinter
  • random
    etc.

So all these modules that I listed, i'll tell you how to use, step by step! ;) But wait, what are modules?

Modules are like packages that are pre-installed in python. You just have to fully install it, which is the module(please correct me if im wrong). So like this code:

When you do this, you successfully import the os module! But wait, what can you do with it? The most common way people use the os module is to clear the page. By means, it clears the console(the black part) so it makes your screen clear-er. But, since there are many, many, many modules, you can also clear the screen using the replit module. The code is like this:

But one amazing thing about this importing is you can make things specific. Like say you only want to import pi and sqrt from the math package. This is the code:

Let me mention that when you do this, never, ever add an and. Like from ... import ... and .... That is just horrible and stupid and... Just don't do it :)

Next is the time module

You can use the time module for:

  • time delay
  • scroll text

And yeah, that's pretty much it (i think)

Note:

All of the import syntax is the same except for the names

Next is tkinter, turtle

You can use the tkinter module for GUI's (screen playing), you can import it in a normal python, or you can do this in a new repl.

You can use the turtle for drawing, it isn't used much for web developing though.

The math and sys

The math is used for math calculations, to calculate math. The sys is used for accessing used variables. I don't really know how I could explain it to you, but for more, click here

Random

The random module is used for randomizing variables and strings. Say you wanted to randomize a list. Here would be the code:

The output would be a random choice from the variable/list. So it could be pie, JBYT27, cat, or dog. From the random module, there are many things you can import, but the most common are:

  • choice
  • randrange
    etc.

And that's all for modules. If you want links, click below.

Hum ok pretty decent tutorial, some tips:

for comments, you can also have multiple line comments:

  1. If and Else Statements

elif...?

  1. Common Modules
    Common modules include:
    os
    time
    math
    sys
    replit
    turtle
    tkinter
    etc.

never heard of the "etc." module lol

The most common way people use the os package is to clear the page.

how?

whateveryouwanttoputhere = input("What is your name?")

pretty long variable, not really recommended..

you can also clear the screen using the replit package

how? examples?

and the random module (randint, randrange, choice)?

and you should prolly include more examples, especially on the modules. also what about variables? for loops? while loops? lists? you're spending a bit more time on the modules than other python ueufl things tbh..

but thank for ping I guess. Maybe try adding some more things to the tutorial, but otherwise, nice start! :D

JBloves27

Ok, thx for the suggestion! Its my first tutorial too, so im prob gonna be bad, lol @Bookie0

Bookie0

@JBYT27 cool np! :D

JBloves27

Elipie said I couldn't fix too much, but later on a different tutorial, i'll do what you said! :) Thanks btw! @Bookie0

Bookie0

@JBYT27 wdym? you can and should always try ti fix things ig :)

JBloves27

@Bookie0, ik, but bc it's a submission... ima make a editted v. later ;)

Bookie0

@JBYT27 hum well ok then, ig you could say that what you edit isn't part of the submission, but if you make another post edited, make sure to edit/add many more things, so that it's not just almost the same thing!

Bookie0

@InvisibleOne but os.system('clear') can be used not only on the repl.it IDE i think

InvisibleOne

Yeah, it doesn't work on my other IDE's @Bookie0

Bookie0

@InvisibleOne ya, tis why os.system('clear') superior lol :)

StevenVoronko

A nice, structured and concise tutorial. I recommend changing this part though so as to avoid confusion;

The output would be a random choice from the variable/list. So it could be pie, JBYT27, cat, or dog. From the random module, there are many things you can import, but the most common are:

  • choice
  • range
    etc.

I recommend changing the range to randrange, syntax: randrange(start, stop, step), since randrange() is the module included in the 'random' library which will create a list of integers and return a random number from said list, whereas the range function, syntax: range(start, stop, step), is a built-in function that only creates a list of integers in a given range, commonly used in for loops as an Iterator

JBloves27

ah, ok. Thanks for the suggestion! @StevenVoronko

thank u very much i have also posted a simple addition program pls see it

JBloves27

Thanks! Glad I helped! Ok, sure! @pyashika

BoyAhmed

u know when i use the if statements then how comes when i use the hashtag it doesnt turn green

JBloves27

the green you can just ignore. it only happens usually with complexity stuff and module stuff. @BoyAhmed

BoyAhmed

@JBYT27 so i dont have to do the green part?

BoyAhmed

@BoyAhmed and thanks for replying so fast i really appreciate it
:)

JBloves27

Yeah. lol, np! glad you learned something! @BoyAhmed

@JBYT27 ur welcome. i thought this was for javascript for a sec and tried coding with it then realized it was for python XD

JBloves27

XD hope u learned something! @bowmand117

[deleted]

@JBYT27 i did. before this, i only knew block coding on https://www.scratch.mit.edu, and even then i wasnt that good.

JBloves27

cool! Glad you learned somethin! Check out the other python tutorial links as well, they are much better than mine, lol @bowmand117

catspython

You CAN use pluses, but you can't put strings and ints together, but also you can make ints strings w/ the str() funcion by putting a int into the funcion like this, str(5[it can be any int]) this outputs this, 5, or, "5"

JBloves27

Oh, ok. Thx for the tip! @catspython

catspython

@JBYT27 Your welcome, I didn't know that you can use commas, nor that f-strings even existed!

JBloves27

Lol, glad I helped as well! @catspython

OlauPla

Ok, going to be hones haven't read it all because very simple but it looks very good! I
