codePost snippet to automatically finalize all submissions of an assignment

codePost-finalize-all.py

# the codePost Python SDK must be installed: pip install codepost
import codepost

# variable parameters
# get the API key here: https://codepost.io/settings
API_KEY = "... see above where to get this ..."
COURSE_NAME = "COS126"
COURSE_TERM = "S2022"
ASSIGNMENT = "Programming Exam 1"

# authenticate
codepost.configure_api_key(API_KEY)

# retrieve the course, and then the assignment
# (will crash if the user of the API key doesn't have access to the course)

course = codepost.course.list_available(name=COURSE_NAME, period=COURSE_TERM)[0]
assignment = course.assignments.by_name(name=ASSIGNMENT)

# iterate over all submissions
for submission in assignment.list_submissions():
    
    # claim submission (must assign a grader, here I assign myself)
    submission.grader = "lumbroso@princeton.edu"
    
    # finalize the submission
    # (so it is visible to students, once the assignment is "published")
    submission.isFinalized = True
    
    # save changes
    submission.save()
