file, modify and store - python-3.x

Today I use python to edit a text.What I can do only read and write.When I use write by the model 'w', it covers the last file.As the same time,I remember the editor 'word'.In our life,every time we modify a text,and save in the same file like 'Control+S'.This action is covering the file before?
I think what the computer can do to a text is not modifying but reading and writing.Can you tell me what I think is true or false and share your knowledge with me?
At last,My English is poor ,sorry --||，but I want to know it. 3Q

How to edit a .raf file?

I am trying to open and edit a .raf file (maybe the Fuji RAW Image File, the result file of a software named SleepSign http://www.sleepsign.com/ ). But I faild to convert it to text file,such as .txt,which I could edit easily and replace the result to what I want. So I can load the replaced-file in SleepSign for manual correction. I test almost all the ways to convert or edit it, but it always break down with a error.I hope for some advises or tools to solve it. Thanks!

You can trie with this one : https://www.onlineconvert.com/by/raf-to-txt-converter.
for infoemration .RAF is a .RAW priority format created by Fuji.

batch file extract numbers from text file with little information

So This is related to my other two posts. Im dealing with extracting text from a text file and analyzing it and I've run into some problems. For A while I've been using a method that sets all the text between two other strings as a variable, but here is the situation I have. I need to extract the speed (numbers) from the below string: "etc...,query":{"ping":47855},"cmts":...etc. The problem is that the text cmts sometimes changes to something else so really I need to extract all the numbers from this:
,query":{"ping":47855},"
One more thing that makes this difficult is that the characters }," Are all over the file. Thank you for helping me! -Lucas EDG Programmer.

By the way, the reason things change is because it looks at info from different servers

Very similar to ther answer I gave you to your first question:

export data from gams to excel

I have a mathematical model and I want to run it 10 times automatically with different data sets which are generated randomly(when the first model stops, start another model automatically). for this purpose I have written the solve statement in a loop . I want to see the result of these 10 models in different sheets of an excel file. how can I do it? is it possible to correct my code?
set k/sheet1*sheet10/;
loop(k,
data generation....
solve statement....
execute_unload 'RESULT.gdx'
execute 'gdxxrw.exe RESULT.gdx o=RESULT.xlsx var=x.l rng='k.t1:0'!a1'
);
I really appreciate your kind helps

Actually, you are pretty close already, you just need to use 'put_utility' instead of 'execute' to make use of the 'k.tl' syntax (note: it is .tl, not .t1):
*dummy put file
file fx; put fx;
set k/sheet1*sheet10/;
loop(k,
solve statement....
execute_unload 'RESULT.gdx'
put_utility 'exec' / 'gdxxrw.exe RESULT.gdx o=RESULT.xlsx var=x.l rng='k.tl:0'!a1';
);
I hope that helps!

Output other than .txt

I'm looking to build a simple program that will simply modify existing output files from an other program so I don't have to open the program and enter a bunch of data the long way. This program is very specific to my domain and has an extension named .wcc. However, when I change the extension of one of these output files to .txt, I get half gibberish :
ÿÿ WPointÿÿ WPolygonÿÿ  WQuadrilateralÿÿ  WMemberDataÿÿ
WLoadÿÿ WLStandardMembersÿÿ WLSavedDesignSettingsÿÿ WLSavedFormatSettingsÿÿ  WLSavedViewSettingsÿÿ WLSavedProjectSettingsÿÿ  WLSavedSettingsÿÿ  WLSavedLoadSettingsÿÿ WLSavedDefaultSettingsÿÿ WLineÿÿ WProductÿÿ WBeamDataÿÿ  WColumnDataÿÿ
WJoistDataÿÿ

WLStandardMembersÿÿ "
There are also musical notes and perpendicular signs which I can't copy paste here. I can sorta read the text, but still not enough to make modifications via txt file. What type of file could this be? Is it even possible to do what I'm trying to do? Thanks!

I am surprised that you are trying to open a .wcc file as a text file (it's contents - as you will see - don't lend themselves to being converted to such a file type); however, the attempt to open the file as a .txt file seems to be specific to your domain.
I noticed part of your question is as follows: "What type of file could this be?"
You are right in thinking that the .wcc file is a rather obscure file type - we don't think about that file type a lot (or are not conscious of it existing). A .wcc file is a WinCam 2000 Cache file that allows WinCam 2000 movies to be previewed in the slide browser - these were often generated by older WinCam 2000 screen recording and editing programs.
Again, the file extension is very rare these days (a Google search only returns ~700 results). But, it appears you have a program that is producing the file, which - as you are saying - "is quite specific to your domain". You may be out of luck with regard to opening them for modification purposes.
Supposedly, you can covert .wac files to .wav files, which are much more relevant to today's technology (and definitely alterable from code); however, without knowing the purpose of the file, e.g. what you are trying to do with the file domain-side, I can't say that this will suit your needs.
Also, the above comments are "correct": changing a file extension will not convert the file to the file extension type. Typically, converters - like a simple software - are needed to convert files.

Changing BUNIT in csh for a FITS file

I'm writing code in .csh, and I'm trying to change the bunit header for a FITS file from K (kelvin) to km/s. How can I do that?
I know in Python I would use new_fitsfile.header['BUNIT']='km/s', but that won't work in the current .csh code, and it's not an option to switch it to Python code.

If this is needed only once, call interactively fv or ds9, move to the header, edit the header card and save the result.
For generic batch jobs, one needs some online FITS editor like fmodhead fmodhead, fthedit, or my fedithead

sed "s:BUNIT = 'K ':BUNIT = 'km/s ':g" old.fits >new.fits
and be very careful to count the significant spaces.
