Answer:
import pandas as pd
# loads the text file as a pandas dataframe
student_file = pd.read_fwf("std_info.txt")
# opens a new text file if the student_avg does not exist
# the file closes automatically at the end of the with statement
with open('student_avg.txt', 'w+') as file:
for row in student_file.iterrows():
file.write(row)
ee = student_file[student_file['major'=='EE']]
cpe = student_file[student_file['major'=='CPE']]
file.write(f'EE average = {ee['EE'].mean()}')
file.write(f'CPE average = {ee['CPE'].mean()}')
file.write(f'Total average = {student_file['EE'].mean()}')
Explanation:
The python program gets the text file as a fixed-width file and loads the file as a pandas dataframe. The dataframe is used to get the total average GPA the student GPA and the average GPA of students in various departments. The results are saved in a new file called 'student_avg.txt'.
It is true that the information provided in text aids can help us to understand a text's content before we even read it.
These text aids will contain bits and pieces from the text, which will make us understand the overall message even before we actually get down to going through the text itself. I believe it is better to actually read the text, and try to understand it on your own, before going to these aids for help.

Explanation:
Answer:
1.) Relative cell reference - A1
2.) Absolute cell reference - $D$2
3.) Mixed cel reference - $D2
Explanation:
In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.
A cell reference is a cell address or a range of cell addresses that can be used in a formula.
There are three types of cell references and they are;
a) Relative reference
b) Absolute reference
c) Mixed reference
A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.
An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.
Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.
What do you mean pieces? Like Laptop components? If so then motherboard,ram,cpu, and psu for a basic laptop so 4 I guess (5 if you want to include a gpu).
