HELP! Hi I'm a newbie in Python,
welcome
A few pointers regarding use of this email list:
- we are a few volunteers who try to help as we can
- please put your responses following the relevant text rather than at
the top
- please reply-all so a copy goes to the list.
- please submit plain text rather than formatting or colors.
- tell us what os and python version you are using
- remove extraneous text
- provide a meaningful subject
- regarding homework
I'm having trouble organizing the FILE into the OUTPUT BELOW. I put
the file into read, then I put it on a list, and my plan is to put the
name and the corresponding grades into a dictionary, using the
elements on the list, but when I print the dictionary, it's not giving
me the result I wanted. MY CODE SO FAR IS SHOWN BELOW THE
OUTPUT. For more details of the assignment, go to this

Thank you so much.

THIS IS MY CODE SO FAR
filename = open("student_grades_hm_5.txt")
infile = filename.read()
mix_list = infile.split()
print "Name | ID | HM1 | HM2 | HM3 | HM4 | Avg. |"
print "______________________________________________________"
Student_one =
{"Name":mix_list[9],"ID":mix_list[5],"HM1":0,"HM2":mix_list[3],
"HM3":mix_list[1],"HM4":mix_list[7]}
print Student_one
You seem to be missing a number of basic concepts. It is hard to tell
how much help is allowed by your instructor.
Did you successfully complete the preceding assignments? Since the
"purpose" is to use lists, file i/o, loops and formatted print I assume
you already know how to use split and dictionaries. True?
What elements of the "purpose" are giving you trouble? Since I see no
loop or formatted print I assume these are giving you grief.
I suggest you start with a bit of pseudo-code to express the structure
of the program.
Your program should not refer to the keys explicitly as you have done in
the line starting with Student_one = nor should it refer to the list
elements by number (that implies knowledge of the structure of a
particular line of the file.
I also suggest you examine the results of each step by entering the
lines at the interactive prompt, then displaying the value of the newly
created variable. You will be surprised by what you see!
My personal guess is that you have not done the prior exercises or else
the instructor is expecting miracles.
Do what you can to improve things then return with more questions.
