In my spare time, I will be learning about Machine Learning, Artificial Intelligence, Data Science and other topics where Python is the interpreted language of choice.
Below are some fast notes I cleaned up to share to however is interested. Disclaimer: I am not responsible of the content or how you use the content. The responsibility fall on you.
We can import modules using the import keyword.
Note: Remember to use 4 spaces for indentation and use UTF-8 encoding with your editor when saving py files.
Functions
Fetch words. Assume this is in the words.py file:
from urllib.request import urlopen
def fetchWordsFromUrl(url):
with urlopen(url) as content:
words = []
for each_line in content:
array = each_line.split()
for each_word in array:
words.append(each_word)
return words
|
Using words.py file with python:
>>> import words
>>> words.fetchWordsFromUrl('https://wordpress.org/plugins/about/readme.txt')
|
Running as Script or Repo
import sys
from urllib.request import urlopen
def fetchWordsFromUrl(url):
with urlopen(url) as content:
words = []
for each_line in content:
array = each_line.split()
for each_word in array:
words.append(each_word)
return words
if __name__ == '__main__'
fetchWordsFromUrl(sys.argv[1])
|
Other Functions
Bytes to Int 32:
def _bytes_to_int32(b):
return b[0] |
b([1] << 8) |
b([2] << 16) |
b([3] << 24)
|
Int 32 to Bytes:
def _int32_to_bytes(i):
return bytes( (i & 0xff,
i >> 8 & 0xff,
i >> 16 & 0xff,
i >> 24 & 0xff) )
|
Even or Odd:
def isEvenOrOdd(n):
return n % 2 == 0
|
Square:
def square(n):
return n * n
|
Note: Code Execution.
$ python3 code.py 99 |
