尝试读取 Python 中的 txt 文件时，列表索引超出范围

Question

I want to read a txt file in Python. The text file consists of 3 columns, all are separated by a ','. One column represents the ID, one for a random float number, and one for the assigned attribute (solo, not solo, acc).

My goal is to convert values for 'solo' and 'acc' to 'not solo', and afterwards calculate the variable y.

The user is asked to enter an ID (number) in. Then I want to convert the lines of the txt file into a list and search for the remaining values, eg User enters in: 45 --> I want to search for the assigned value, then convert it to 'not solo' and calculate y. In the end, I want to print the assigned value in the unit 'not solo' as well as the y-calculation.

However, when I am trying to find the values, I get an error saying that my list index would be out of range. Does anyone have a clue how to fix this?

I am browsing for hours but I can't find a solution that works.

Thank you so much!

for file in file_content:

file = file.strip()

ID_q = int(input("Please enter number [else enter 'finished']:"))
ID = ID_q + 1

if ID_q != "finished":

                x_result = round(x_result, 2)

                function = float("f(x) = {0}".format(y))
                function = round(function, 2)

                print(x_result)

                print(x)

When you do this:

fobj = open('test.txt', 'r')
file_content = fobj.readline()
fobj.close()

You are reading only one line, not the whole file.
