For finding course info @ BU Download PKL File

↓ in doc.ipynb

Query Courses

To load pickle file

from course import Course
import pickle

# Should take around a minute
with open("courses_directory.pkl", "rb") as f:
  course_directory: dict[str, Course] = pickle.load(f)

Find Class

College: str = "CAS" # Three letter acronym like "CAS"
Department: str = "BI" # Two letter acronym like "BI"
Number: int = 203 # Three numbers like "203"

c: Course = course_directory[f"{College} {Department} {Number}"]

Methods

Get Course Name, Code, and Attr

College, Department, Number = c.College, c.Department, c.Number

code: str = c.__repr__() # ex. CAS BI 203 

class_name: str = c.getCourseName() # ex. Cell Biology

Get PreReqs and CoReqs and Attr

pre_pres, co_reqs, leads_to = [c.UndergradReq + c.GradReq, c.UndergradCoReq + c.GradCoReq, c.Post]

# Returns clips with relivant info for course reqs
pre_req_text: dict[str, str] = c.getPreReqsText()

# Returns classes for each category
pre_req_classes: dict[str, list[Course]] = c.getPreReqs()

# Keys reversed
_ = {
        "Graduate Prerequisites:": "gpr",
        "Graduate Corequisite:": "gcr",
        "Undergraduate Prerequisites:": "upr",
        "Undergraduate Corequisites:": "ucr",
        "Prerequisites:": "pr",
        "Corequisites": "cr" 
}

Hubs

Hubs: list[str] = c.getHubs()

tmi (to much information)

c.tmi() # returns str

Webpage and url

from bs4 import BeautifulSoup

website: BeautifulSoup = c.webpage

description: str = c.getDesc() # id='course-content' of course page

url: str = c.url

link: str = c.link # kwarg for c.__init__() for web scraping

valid_link: bool = c.valid_link # False if page not found

Construct Course

# Broken right now, have to declare Course class in same place as course_directory

name: str = "CAS BI 203"

c: Course = Course(name, link=None, cd=course_directory)

Webscraping

Edit all_colleges if I missed one

# Caution does a lot, broken have to declare BUCourseBranch class in same place as course_directory

from main import BUCourseBranch

save_branch = BUCourseBranch()
save_branch.run() # or save_branch.__repr__()
