check_files(["test1.txt","test2.txt","test3.txt"])
print(hw3_generator(10))
print(hw7_generator(10,3,10))
print(hw11_generator(10,5))
print(hw13_generator())
print(derivative_judge("3*x**2","x**3"))
print(hw5_judge(open("out.txt").read(), open("data.txt").read()))

NLP metric

Calculate BLEU score

from wzk.nlp import bleu
print(bleu("they are good", "they are not good", k=2))

Useful Tools

simple version control system

(1) Use in shell (command line)

Note: support Linux and Mac OS ( try git bash if using Windows)

#install
#change PATH to the absolute path of wzk/luna.py
#change .bashrc if using another shell. e.g. ~/.zshrc
echo "alias luna='python PATH/luna.py' " >> ~/.bashrc
source ~/.bashrc

mkdir test
luna init
touch blablabla
luna commit "first commit"
touch hahaha
luna commit "second commit"
luna log
luna reset 1
luna reset 2
luna history
luna delete 1
luna info
luna discard

(2) Use in python

from wzk.luna import *
p = "/Users/wzk/Desktop/"
init(p)
makefile(p, "1")
commit(p, "commit 1")
makefile(p, "2")
commit(p, "commit 2")
revise(p, 2, "commit 3 new message")
reset(p, 1)
reset(p, 2)
history(p)

send email

Send email with SMTP

import wzk
mail_host = ...
mail_user = ...
mail_pass = ...
sender = wzk.parser.MailSender(mail_host, mail_user, mail_pass)
sender.send_mail(title="hi~", content="nothing~", receiver=None)

check web page update

Automatically check web page and send notification email upon update

import wzk
mail_host = ...
mail_user = ...
mail_pass = ...
checker = wzk.parser.WebPageUpdateChecker(mail_host, mail_user, mail_pass)
checker.check("www.baidu.com", interval=10)

check system information

see information on your system and python

from wzk.os import *
show_os_all_info()
show_python_all_info()

For Developers

improved data structure

Dictionary supporting inverse-mapping and attribute-indexing

Number type supporting setting bound and loop

from wzk import DD, N

a = DD({"good": "kk"})
a.bad = "nyima"
print(a.good)
print(a["bad"])
print(a.inv())
print(a.inv().inv())

b = N(4, upper_bound=8, lower_bound=3)
b += 5
c = N(4, upper_bound=8, lower_bound=3, loop=True)
print(c+5)

interestring utensils

Several interesing utensils

import time
from wzk import ErrorFucker, Separate, Clock

with ErrorFucker(raises=False) as ef1:
    d1 = int("f")

with Separate("separate zone", count=True) as s:
    print("ohhh")

with s:
    with Clock("test") as c:
        time.sleep(2)
    print(c)

with ErrorFucker(raises=True) as ef2:
    d2 = int("d")

simplified pytorch(?)

Scalar autograd mechanism

from wzk.autograd.thing import *

a = thing(2)
b = thing(3)
c = a + leaky_relu(b)
d = thing(5) # a + a*b
e = tanh(d) # (a + a*b) * (a*b) = a^2(b + b^2)
f = relu(c) + sin(e)
g = log(f)

g.backward()
print(a, b, c, d, e, f, g)
