How to avoid error: name 'score history' is not defined in modules section in Python for absolute beginners by Mark Winerbottom

Question

I'm on the course Python for absolute beginners by Mark Winterbottom, the Modules Section. I've made a follow-along task, and I literally followed every step, but it gives me an error Mark doesn't get. Please, help. Here is a full code (first Module part, and then the Script):

"""
Module for exam predictions. 
"""

def get_avg(score_histrory):
    """Takes a list of previous grades and returns average."""
    return sum(score_history) / len(score_history)

def predict_score(score_history, min_score=0):
    """Takes a list of previous persentage grades and returns the average."""
    score_avg = get_avg(score_history)
    if score_avg < min_score:
        return min_score 
    
    return score_avg 
"""
Functions for calculating results.
"""
A_THRESHOLD = 70
B_THRESHOLD = 60
C_THRESHOLD = 50
D_THRESHOLD = 40
E_THRESHOLD = 30 

def get_grade(score):
    """Accepts a score and returns a letter version."""
    if score >= A_THRESHOLD:
        return 'A'
    elif score >= B_THRESHOLD:
        return 'B'
    elif score >= C_THRESHOLD:
        return 'C'
    elif score >= D_THRESHOLD:
        return 'D'
    elif score >= E_THRESHOLD:
        return 'E'
    
    return 'F'

"""
Srcipt for proccessing students grades.
"""
from grades.predict import predict_score 
from grades.results import get_grade 

score_history = [5, 10, 10, 2]

predicted_score = predict_score(score_history)

predicted_grade = get_grade(predicted_score)
print(f'The students predicted grade is: {predicted_grade}')

NameError: name 'score_history' is not defined

Thanks a lot. It's my first time asking a question here. Hope for your support.

I think you just have a typo in your code "histrory" and not "history":

def get_avg(score_history):
"""Takes a list of previous grades and returns average."""
    return sum(score_history) / len(score_history)
