🔒 Error Appending info from .txt file to a variable

[sleek ermine]

I'm building a program to reada student ID (MXX) and exam grades from an input file, calculate the average, and display the result on screen and write it to an output file. I need to first write the grades to the variable GradeList, but the variable doesn't seem to be getting the info from the .txt file. I'm not sure why GradeList isn't getting updated. Thoughts?

Thank you

Correct

I don't think I have one

Could you type an example?

[cunning canopy]

!e

text = """x1 1 2 3
x2 4 5 6
x3 7 8 9
"""

for line in text.splitlines():
    name, *values = line.split()
    print("name:", name, "average:", sum(int(value) for value in values) / len(values))

[mint geyser]

:white_check_mark: Your 3.12 eval job has completed with return code 0.

001 | name: x1 average: 2.0
002 | name: x2 average: 5.0
003 | name: x3 average: 8.0

[sleek ermine]

So how much of the code would I have to exchange for that statement?

[errant berry]

does the output file have only averages?

[sleek ermine]

Ot

[sleek ermine]

It has the student ID's and the averages

[errant berry]

ok, trying

[cunning canopy]

Please don't post the solution. This is homework

@errant berry

[errant berry]

sure man

[cunning canopy]

It's about getting to the solution

I'm in VC with them

[sleek ermine]

It helps. I'm trying to understand what code I should then delete since I have simplified the formula.

I need the average function for the HW

I think it helps

Yep

That's correct

[errant berry]

are you sure you are writing the average to the file?

[sleek ermine]

Just playing with the code, would it look something like this?

[sleek ermine]

You still there?

[cunning canopy]

I'm here

Yeah, that is looking good. You'd still want your file IO stuff in there, but it should be a bit easier now that the logic is reduced. You don't need total_test_scores=3 in your function.

Make sure that you write to your output file after you have all of the info you need to write

[sleek ermine]

Mind clarifying what file IO stuff means? Like so:
https://paste.pythondiscord.com/VZYA
Also, I'm getting the error:
----> 4 for line in gradesFile.splitlines():
AttributeError: '_io.TextIOWrapper' object has no attribute 'splitlines'

[cunning canopy]

file IO just means file input/output. It's opening, reading and writing to files like you now have back in your code.

splitlines() is just for strings. You need your old method which was just looping over the file itself.

[zenith kindle]

            ID += line[index]
            index = 0
           #Skip spaces after the id```

[mint geyser]

Hey @zenith kindle!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

[zenith kindle]

            ID += line[index]
            index = 0
           #Skip spaces after the id 

this code will run forever

[cunning canopy]

We're already past that

[zenith kindle]

good

[cunning canopy]

Once what we discussed is fixed, you'll have one more issue with your output file.

How's it going? @sleek ermine

[sleek ermine]

Good, just making an adjustment

[sleek ermine]

Good news. Got the averages to work and the output file to print. The only thing is that they all print in one line: Here's the new code:

https://paste.pythondiscord.com/D2SA

Thoughts?

[cunning canopy]

Maybe the newline character can help "\n"

[sleek ermine]

It worked! The last part is I need to separate the ID from the average when I print them on the new file: Here's the updated code!

Thank you for all of your help!

[cunning canopy]

Awesome!

Any time!

Cheers

[sleek ermine]

There was one more thing. I need to separate the ID and averages when the value is separated. This is the line that writes the info onto the outfile: outfile.write(ID+''+str(avr)+ '\n')

How could I get the space added?

[cunning canopy]

This is your output line: outfile.write(ID+''+str(avr)+ '\n') - just add the space where it needs to go. Not sure if you noticed that you have an empty string between ID and str(avr).

[sleek ermine]

Perfect! It works! Thank you for all of your help!
