Day 18 of 100

#python #beginners #learning #challenge

So today I did quite a lot and spent a few hours on a project and some challenges. Without further adieu, let's get into what I learnt today.

Ways to Import Modules

Basic Import : import module
from ... import ... : eg. from turtle import Turtle, helpful so that you do not need to call upon that class again and again:
import turtle
t1 = turtle.Turtle()
t2 = turtle.Turtle()
t3 = turtle.Turtle()

from turtle import Turtle
t1 = Turtle()
t2 = Turtle()
t3 = Turtle()

from ... import * : eg. from turtle import * The asterisk means that you import everything, it is useful because then you can just say the fuction you want it to do rather than the module as well. eg: import random

choice([1, 2, 3])

So you don't need to say random.choice()
It can be useful but can also become very confusing as it is not clear what exactly is happening therefore it is not used a lot.

import .... as ... (Alias modules) : This is useful for when the module has a long name. eg. import very_long_name_module as m m.action()

rather than saying :
very_long_name_module.action()

installing modules : Not all modules are built into python. You may need to download the module before you use it.

Extra
Tuple - it is a dataset and you use () brackets for it. It is 'set in stone' meaning that once you make it you cannot modify it in any way. It's used wherever you want a fixed set of data that must not be modified in the program. If you want to modify it you will need to covert it into a list first - list(tuple)

What I built

I'm learning french so I thought it would be fun to add the comments in french(thanks google translate).
