Prototyping 1 (20/09/2020)

JupiterLab

- command language : pythone (also, wiki language. ex. instead of #, use ==headline==)

- run on offline + in browser (easy to publish)

- have its library, with ? at the end (ex. random?), we get its explanation

- with "enter", change the line in the cell

- "enter + shift", command to execute the command -> on the next line, spit out the output immediately (like javascript console)

- consist of "Console" and "Notebook"

Console

-like terminal, command line interface. direct way to see the result, but, cannot be saved

Notebook

- for hybrid publishing interface (but +, console)

- fast editing and publishing possiblle ( faster than using hub)

- Text (Markdown) + Code (Python)

- modifying / rerunning the cell is possible

- Refer "AHOUSEOFDUST.ipynb" on JupiterLab

Phython code

- https://docs.python.org/3/tutorial/classes.html#class-objects

- "17" + 29 -> error / "17" + "29" -> 1729

- x=x+1 same with x+=1

- type : str (for text ex. "17"), int(number), float(number with fractional parts), boolean(true/false), list

- calculation with text is not possible (sauf, * ex."hello"*2 -> hellohello)

- x=["a", "b", "c"] -> x[1]=b / x[-1]=c(negative number starts from the end)

- print() -> empty line output

- for For, the space before inner-command is important

for x in "Michael":
    print(f"hello {x}")
print("End") 

-> hello M 
   hello i
   ... 
   hello l
   End  # appeals only at the end

- input random

random.random -> 0.234546546678

random.randint(0,5) -> 4 (random number between 0-4)

random.randint(0,len(x)) -> 1 (number between 0-2)

random.choice(x) -> c

Generated poem

- A house of dust by Alison Knowles https://hub.xpub.nl/bootleglibrary/read/465/pdf

- My generated poem input and output

import random
from random import choice

ani = ("mosquitos", "pigs", "kangaroos", "tunas", "cats")

cha = ("blue", "laziest", "numbest", "most stinky", "dullest")

for x in range (10) :
    n = random.randint(3, 30)   # when the number is too big, doesn't give a sufficient random one (like, 99999 -> always, a number of 5 ciphers)
    a = choice(ani)
    c1 = choice(cha)
    c2 = list(cha)   # to remove an element in tuple, must change to list (list = ["",""], tuple = ("","")
    c2.remove(c1)    # c2 is a list except the result of c1
    c2 = choice(c2)
    print(f"Amongst the numbers of {n} of {a},")
    print(f"the {c1} one and {c2} one are selected as the king and queen of {a}!")
    print()
