ValueError: need more than 0 values to unpack (Python 2)

I am trying to replicate another researcher's findings by using the Python file that he added as a supplement to his paper. It is the first time I am diving into Python, so the error might be extremely simple to fix, yet after two days I haven't still. For context, in the Readme file there's the following instruction:
"To run the script, make sure Python2 is installed. Put all files into one folder designated as “cf_dir”.
In the script I get an error at the following lines:
if __name__ == '__main__':
cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
os.chdir(cf_dir)
cf = pd.read_csv(cf_file)
cf_phys = pd.read_csv(cf_phys_file)
ValueError: need more than 0 values to unpack
The "cf_file" and "cf_phys_file" are two major components of all files that are in the one folder named "cf_dir". The "cf_phys_file" relates only to two survey question's (Q22 and Q23), and the "cf_file" includes all other questions 1-21. Now it seems that the code is meant to retrieve those two files from the directory? Only for the "cf_phys_file" the columns 1:4 are needed. The current working directory is already set at the right location.
The path where I located "cf_dir" is as follows:
C:\Users\Marc-Marijn Ossel\Documents\RSM\Thesis\Data\Suitable for ML\Data en Artikelen\Per task Suitability for Machine Learning score readme\cf_dir
Alternative option in readme file,
In the readme file there's this option, but also here I cannot understand how to direct the path to the right location:
"Run the following command in an open terminal (substituting for file names
below): python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile
jobDataFile OESfile
This should generate the data and plots as necessary."
When I run that in "Command Prompt", I get the following error, and I am not sure how to set the working directory correctly.
- python: can't open file 'cfProcessor_AEAPnP.py': [Errno 2] No such file or directory
Thanks for the reading, and I hope there's someone who could help me!
Best regards & stay safe out there during Corona!!

cf_dir, cf_file, cf_phys_file = sys.argv[1:4]
means, the python file expects few arguments when called.
In order to run
python cfProcessor_AEAPnP.py cf_dir cf_file cf_phys_file task_file jobTaskRatingFile jobDataFile OESfile
the command prompt should be in that folder.
So, open command prompt and type
cd path_to_the_folder_where_ur_python_file_is_located
Now, you would have reached the path of the python file.
Also, make sure you give full path in double quotes for the arguments.

File content as PyCharm run configuration parameters

I'm trying to launch may main Python script with some arguments listed in a txt file (config.txt).
Because parameters change almost every launch and I dont want to type them every time. They are not literally a "config" but I didn't find the correct file name (that's an other story).
See below:
-param1 1
-param2 2
-verbose
Using Run Configuration of PyCharm.
I would like to finally do something like :
python C:\somewhere\main.py -param1 1 -param2 2 -verbose
Instead of current behavior :python C:\somewhere\main.py config.txt
Which, by the way, is missed understood by the program (obviously).
#32951846
I already tried windows for loops in the section "before launch: activate tools":
$: for /f "delims=" %x in (config.txt) do set ARGS=%ARGS%%x
$: python C:\somewhere\main.py %ARGS%
But it only keep the last line of the config.txt inside ARGS.
#51948712
I also tried to pipe the content of the file into my python main program like:
python C:\somewhere\main.py < config.txt
But it do not work neither.

Am I right that you'd like to see something like https://youtrack.jetbrains.com/issue/PY-5543?
Consider using the following plugin: https://plugins.jetbrains.com/plugin/7861-envfile/

This is not exactly what you were asking for, but you can follow this guideline to store the run configurations in a file and then modify the file, share it or add to git.
The key steps are to tick the box "Store as project file" in PyCharm's "Run/Debug Configurations" window. This will create the new subfolder "runConfigurations" in the ".idea" folder in the project folder.
The folder will contain an xml file with the line
<option name="PARAMETERS" value=""arg1" "arg2"" />
where "arg1" and "arg2" are the arguments which are passed to your script.

Print custom formatted text into cmd console

I just started learning python in order to do some stuff for the company I work for. I want to add a command line option like -doc but Ì somehow struggle with adding color or any other custom text format to my documentation (to be printed in cmd).
I have following problems:
1. Ansi escaping doesn't work as I expect when reading tutorials on the internet:
This code: print('\033[31m' + 'Hello' + '\033[0m') doesn't escape at all so I end up with this output: [31mHello[0m
2. I can't import colorama because my users have a plain python installation and I can't just add libraries to it. So my plan would be to add colorama to my project structure.
To 1: Do I misunderstand something important or has someone an idea what I`m doing wrong?
To 2: Is there a way to install colarama into my project without any changes to the plain python installation or dependencies to the outside of my project?
... I would accept any other solution to my problem.

Just use batch to do that.
Code:
#echo [31mHello[0m

Python for Data Analysis, Chapter 2, first example

I'm following along with the examples in a translated version of Wes McKinney's "Python for Data Analysis" and I was blocked in first example of Chapter 2
I think my problem arose because I saved a data file in a wrong path. is that right?
I stored a file, usagov_bitly_data2012-03-16-1331923249.txt, in C:\Users\HRR
and also stored folder, pydata-book-mater, that can be downloaded from http://github.com/pydata-book in C:\Users\HRR\Anaconda2\Library\bin.

Depends.
You might change the location you save your File or eddit the path you give to your code in Line 10. Since you're yousing relativ Paths i guess your script runs in C:\Users\HRR\Anaconda2\Library\bin, which means you have to go back to C:\Users\HRR or use an absolute Path ... or move the File, but hell you don't want to move a file every time you want to open it, like moving word files into msoffice file to open it, so try to change the Path.
And allways try harder ;)

In python open() will open from the current directory down unless given a full path (in linux that starts with / and windows <C>://). In your case the command is open the folder ch02 in the directory the script is running from and then open usagov_bitly_data2012-03-16-1331923249.txt in that folder.
Since you are storing the text file in C:\Users\HRR\usagov_bitly_data2012-03-16-1331923249.txt and you did not specify the directory of the script. I recommend the following command instead open(C:\\Users\\HRR\\usagov_bitly_data2012-03-16-1331923249.txt)
Note: the double \ is to escape the characters and avoid tabs and newlines showing up in the path.

Problems with Encoding in Eclipse Console and Python

I guess I need some help regarding encodings in Python (2.6) and Eclipse. I used Google and the so-search and tried a lot of things but as a matter of fact I don't get it.
So, how do I achieve, that the output in the Eclipse console is able to show äöü etc.?
I tried:
Declaring the document encoding in the first line with
# -*- coding: utf-8 -*-
I changed the encoding settings in Window/Preferences/General/Workspace and Project/Properties to UTF-8
As nothing changed I tried the following things alone and in combination but nothing seemed to work out:
Changing the stdout as mentioned in the Python Cookbook:
sys.stdout = codecs.lookup("utf-8")-1
Adding an unicode u:
print u"äöü".encode('UTF8')
reloading sys (I don't know what for but it doesn't work either ;-))
I am trying to do this in order to debug the encoding-problems I have in my programs... (argh)
Any ideas? Thanks in advance!
EDIT:
I work on Windows 7 and it is EasyEclipse

Got it! If you have the same problem go to
Run/Run Configurations/Common and select the UTF-8 (e.g.) as console encoding.
So, finally, print "ö" results in "ö"

Even this is a bit old question, I'm new in StackOverflow and I'd like to contribute a bit. You can change the default encoding in Eclipse (currently Neon) for the all text editors from the menu Window -> Preferences -> General -> Workspace : Text file encoding
