I’m trying to open a file on my computer but it won’t open and is saying that the file doesn’t exist and I am also getting the error that “COP10000C” is not defined even though it is please help I need to bring my grade up.)

Posting a screenshot like that? Ouch! 
You should definitely do what @csm10495 says.
As for your code, it asks for the name of a file and then calls process_file with the value of COP1000C, which is a variable that has not been defined.
The function process_file, incidentally, always tries to open a file called “COP1000C.txt”. It doesn’t do anything with whatever was passed in via the parameter COP1000C. Why does the parameter have that name?
What the code should be doing is calling process_file(filename), the function should be defined with def process_file(filename), and that function should be opening the file with with open(filename) as file:.

Hi, when I do that is says Error processing file: [Errno 2] No such file or directory: ‘COP1000C.txt’
Would you like to process another file (y/n)?
Did you type in “COP1000C.txt” as the filename?
If you did, then it’ll look for that file in a current directory, wherever that is.
You should enter the full path of the file.
Yes I put it like this
# Function to process a file and generate a course grades summary report
def process_file(filename):
try:
# Open the file in read mode
with open('COP1000C.txt', 'r') as file:
# Read all lines from the file
lines = file.readlines()
# Extract course information from the first three lines
course_info = lines[:3]
# Extract student records from the remaining lines
students = lines[3:]
# Extract individual course information
course_number_description = course_info[0].strip()
instructor_name = course_info[1].strip()
term = course_info[2].strip()
# Group student records (name and grade are consecutive lines)
student_records = [students[i:i+2] for i in range(0, len(students), 2)]
# Extract grades from student records and convert them to integers
grades = [int(record[1]) for record in student_records]
# Calculate number of passed students (grade >= 60)
passed_students = len([grade for grade in grades if grade >= 60])
# Calculate number of failed students
failed_students = len(grades) - passed_students
# Calculate passing percentage
passing_percent = round((passed_students / len(grades)) * 100)
# Calculate average grade
average_grade = round(sum(grades) / len(grades))
# Set console width for printing
console_width = 50
# Set title for the report
title = "College Grades Summary"
# Print title with underscores on either side
print("_" * console_width)
print(title.center(console_width))
print("_" * console_width)
# Print course information
print(course_number_description)
# Print instructor name and term
print(f"Professor: {instructor_name}\tTerm: {term}\n")
# Print header for student records
print("Student Name\t\t\tGrade")
# Print line separator
print("__________________________________________________")
# Print each student record with name and grade
for record in student_records:
print(f"{record[0].strip():<32}{record[1].strip()}")
# Print header for performance summary
print("\nStudents' Performance")
# Print line separator
print("__________________________________________________")
# Print performance summary: number of passed and failed students, passing percentage, and average grade
print(f"Passed: {passed_students}\tFailed: {failed_students}")
except (IOError, FileNotFoundError) as e:
# Handle exceptions related to file processing and print an error message
print(f"Error processing file: {e}")
# Main loop to continuously process files until the user decides to stop
while True:
filename = input("Enter name of course file: ")
process_file(filename)
another_file = input("Would you like to process another file (y/n)? ")
if another_file.lower() != 'y':
break
This:
with open('COP1000C.txt', 'r') as file:
will always try to open “COP1000C.txt” in the current directory, wherever that is, no matter what was passed in.
Presumably, that file is not in the current directory.

Yea I’m not sure how to get to it
You ask the user for the full path of the file, including the directory and the extension, and the program passes that to process_file:
while True:
path = input("Enter path of course file: ")
process_file(path)
another_file = input("Would you like to process another file (y/n)? ")
if another_file.lower() != 'y':
break
process_file then opens the path that it was passed:
def process_file(path):
try:
# Open the file in read mode
with open(path, 'r') as file:
# Read all lines from the file
... # etc
So with this when asked anger path to course file do I type in COP1000c. Because when I did I still got Error number 2
When it asks for the full path, type in the full path, which, from the original screenshot, I see is C:\Users\Admin\OneDrive\Documents\COP1000C.txt.
I pasted it and I got error 22 now that says invalid argument
I tried adding different slashes to see if it made a difference
Please don’t post screenshots.
Copy and paste any code or traceback, and in order to preserve formatting, select the code or traceback that you posted and then click the </> button.
You’re supposed to type in only the path.
Don’t put quotes around it. It isn’t some code in a program.
