Add-ons to your Python code to make it better!

Hello hello hello wassup people,

I’m just going to show you some quick things to make your Python code cool!

1) Screen Clearing

Screen clearing is very useful; you use it to, well, clear the screen. I like it a lot because you can use it to erase everything so that it looks better, and so that not too much text crowds the screen!

For the screen clearing, you need to just:


os.system('clear')

You can copy this code and put it every time you need to.
However, i prefer to create a function, so that i dont need to keep putting that (even if its just a few letters...):


def sc():
     os.system(‘clear’)

As you can see I called the function sc(),which stands for screen clear, so each time I want to clear the screen, i just call that function. It makes it just a bit shorter.
(Thanks to @ArjunSS1 for helping me with the screen clear)

2) Typewriter effect

Now this typewriter effect is super cool, because it makes the text print one letter at the time. You can regulate it so that it prints the text fast or slow.
First the imports:


import sys, os, curses
import time

And this is the code:


st = 0.04
def sp(str):
  for letter in str:
    sys.stdout.write(letter)
    sys.stdout.flush()
    time.sleep(st)
  print()

I usually put it at 0.04because it prints it not too fast and not too slow. But you can change it. Just change the value after st

Each time you want to do this typewriter effect, just do:


sp(“Hello World”)

Output:


Hello World

3) While loops to go back to menu (very basic)

Personally, I’m not a pro in loops, but this is what I do sometimes. Imagine you want to do sort of menu option, like this:


print (“This is the menu”)
action1 = input(“Type hello for some greetings >  ”)
if action1 == “hello”:
    print(“Hola”)
    print(“Bonjour”)
    print(“Aloha”)

So when the user types hello, several greetings will appear. But what if the user types something else by accident? Then, you could add an else statement, and saying something like “invalid”, and then the user could return to the menu,
This is how you do that:


back_to_menu = True

while back_to_menu == True:
     print (“This is the menu”)
     action1 = input(“Type “hello” for some greetings >  ”)
     if action1 == “hello”:
          print (“Hola”)
          print (“Bonjour”)
          print (“Aloha”)
      else:
           print (“You wrote something else than “hello”! ”)
           back_to_menu = True

So when you put back_to_menu = True at the end of the else statement, the user will arrive back at the menu!

4) Colors

This is how to make colors in Python.

Pretty simple, just copy paste these colors (because typing them would be to long...)


# colors
black = "\033[0;30m"
red = "\033[0;31m"
green = "\033[0;32m"
yellow = "\033[0;33m"
blue = "\033[0;34m"
magenta = "\033[0;35m"
cyan = "\033[0;36m"
white = "\033[0;37m"
bright_black = "\033[0;90m"
bright_red = "\033[0;91m"
bright_green = "\033[0;92m"
bright_yellow = "\033[0;93m"
bright_blue = "\033[0;94m"
bright_magenta = "\033[0;95m"
bright_cyan = "\033[0;96m"
bright_white = "\033[0;97m"

So to use it, just put the color before the text:


print(bright_yellow + “text here”)

This also works with the slowPrintI mentioned earlier

5) Some functions you can use

I always use these functions in my code because they are kinda like shortcuts. Less is more!


# for putting some space in between stuff
def space():
  print()
  print()

# prompt the user to press enter
def enter():
  input("Enter to continue\n> ")
# btw: \n is for another line

So that’s about it i know this tutorial isn’t very good, but I hope it helped you and you enjoyed it.
Lastly, nothing is under copyright, so go on and copy paste!
