You can install the said module directly using: 1## git clone the module-name from its repo, then 2python -m pip install -e ./module-name or in one line (replace the repo accordingly): 1pip install -e git+https://github.com/enzoampil/fastquant.git@master#egg=fastquanthttps://quicktasks.ismael.casimpan.com/post/python-virtualenv/Tue, 27 Jun 2023 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/python-virtualenv/ Best approach in doing development in any language is to have an isolated dev environment. In python, we do it this way: 1python3 -m venv env 2source ./env/bin/activate See more options in https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/https://quicktasks.ismael.casimpan.com/post/python-debugging/Thu, 05 May 2022 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/python-debugging/ Use pdb module in debugging python: 1$ python3 -m pdb pdb_example.py and something like this: 1student@ubuntu:~$ python3 -m pdb pdb_example.py 2> /home/student/pdb_example.py(1)<module>() 3-> class Student: 4(Pdb) continue 50 61 72 83 94 10The program finished and will be restarted 11> /home/student/pdb_example.py(1)<module>() 12-> class Student: 13(Pdb) See https://hub.packtpub.com/debugging-and-profiling-python-scripts-tutorialhttps://quicktasks.ismael.casimpan.com/post/quick-http-server-using-python/Fri, 25 Feb 2022 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/quick-http-server-using-python/ If you ever need to serve your current directory via http for some reason, this is a quick command in python3: 1~$ python3 -m http.server 8000 Then access http://localhost:8000https://quicktasks.ismael.casimpan.com/post/links-python/Fri, 18 Feb 2022 09:19:11 +0800https://quicktasks.ismael.casimpan.com/post/links-python/ Python Official Documentation Python Package Index or PyPI Python3 Standard Library Python3 Docs Learn Python PyNative Learn Python in Y minutes Python Frameworks Django Project Flask Bottle Others Beautiful Soup - HTML & XML web scraping Stackoverflow: Other alternatives to venv Build REST API with Django REST Framework in 30mishttps://quicktasks.ismael.casimpan.com/post/basic-python-datatypes/Sat, 12 Feb 2022 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/basic-python-datatypes/ These are the three core data types in python. Of course there are strings, int too. I'm listing this here as I often forget these: List Somewhat similar to tuple (see below) but changeable. Uses square brackets instead of parenthesis in tuple. 1>>> kirk = ["James Kirk", 34, "Captain", 2265] 2>>> type(kirk) 3<class 'list'> Tuple A tuple is a collection which is ordered and unchangeable. 1>>> mytuple = ("apple", "banana", "cherry") 2>>> type(mytuple) 3<class 'tuple'> Dictionary 1>>> comedian = {'name': 'Eric Idle', 'age': 74} 2>>> type(comedian) 3<class 'dict'> 4>>>https://quicktasks.ismael.casimpan.com/post/pythonic-code-using-enumerate/Sat, 12 Feb 2022 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/pythonic-code-using-enumerate/ Use enumerate to iterate to each list's element 1>>> # Pythonic Example 2>>> animals = ['cat', 'dog', 'moose'] 3>>> for i, animal in enumerate(animals): 4... print(i, animal) 5... 60 cat 71 dog 82 moose If the index is not important, use "_" in place of "i": 1>>> # Pythonic Example 2>>> animals = ['cat', 'dog', 'moose'] 3>>> for _, animal in enumerate(animals): 4... print(animal) 5... 6cat 7dog 8moose Or more simply, without using "enumerate" function:
