I have a script that automates some things on Chrome with Selenium, which works like a charm. The only problem is that at some point I want to upload a file from my computer to the webpage. For this purpose, a Windows system popup will show in which I need to navigate to the correct file, followed by clicking 'Open' to upload the file.
It seems that Selenium is not able to handle this, but what is able to handle this then? I'm also not sure how to focus the script to the popup (or if that is even needed).
I hope someone can help.
To upload file with Selenium:
1 Find the input element with type=file.
2 Call send-keys selenium command and send the file absolute path text to the input-file element.
file_input = driver.find_element_by_xpath("//input[#type='file']")
file_input.send_keys("D:\\Documents\\user-logo.jpg")
No additional clicks required.

The problem:
I'm currently working on a programming language, which uses a simple python interpreter. The interpreter loops over every line with a bunch of if-statements.
The file extension I'd like to use is .ccp.
So far my progress. I want the computer to recognise .ccp files as a CalcScript file, and open it with the script.
I don't want to have a default filename which I can open using text = open("filename.idk","r").read(), I want to open a file like a 'normal' file. You double-click on the file in explorer, and it opens it in the python script. Regardless of the filename.
What I've tried:
Tinkering with the default applications in settings
Tinkering in regedit
Converting my .py file to .exe
Scouering the internet
My code:

Sorry for bad English if there was any.
Summarizing my comments on the question, you can follow the steps below to achieve what you are asking:
Use sys.argv to access the command line arguments. For example the following script will just print all the arguments given to it:
import sys
print("Given arguments: ", str(sys.argv))
Let's name it myprogram.py.
You can then call it (I think) with: python myprogram.py arg1 arg2 arg3 and it will run and print the command line arguments.
Notice that the first argument (sys.argv[0]) is the script's path. So arg1 would be sys.argv[1], arg2 would be sys.argv[2] and so on.
I am saying to use sys.argv because as far as I remember double clicking a file with an extension which has a default opening program, will open that program with the file path as an argument.
Next step is to package your python script to an executable. This has been already asked and answered for example here (which is a duplicate, where you can follow the question which came before it to see even more examples). I used PyInstaller to test it (and on Windows OS). My command was like:
pyinstaller myprogram.py
... and it generated some folders and files. Specifically the folder dist\myprogram contained the executable along with its dependencies. You can then run your program by double clicking on it in the dist\myprogram folder. It should pop a CLI window, printing the arguments (ie only the program's path, since we called it without any other) and immediately exit. Or you can open a CLI window and run it with a command like:
myprogram argument1 argument2 argumentN
(supposing your current working directory is dist\myprogram) and it will indeed print the arguments.
Finally you have to set it up as the program which by default opens files with .ccp extension. On Windows 10, you can do this via:
Open up File Explorer.
Find a file with .ccp extension (or create one).
Right click on it.
Click on Properties on the dialog that pops up.
Go to General tab (if you are not already there) on the dialog that pops up.
On the Open with: section there is a button which reads Change. Click it.
Select More apps at the bottom of the dialog.
Make sure you have the Always use this app to open .ccp files checkbox selected.
Scroll to the bottom of the dialog and click on the blue text which prompts for manually selecting the default app, which in turn pops up a file chooser. I am not running on English language so it is a bit difficult to translate it exactly (I followed some online pages to actually see the default translation for the previous steps).
Select your executable as the default.
Confirm your choices by selecting Ok, Apply or anything else required.
Then you will also be able I think to change this extention later via:
Settings --> Apps --> Default Apps --> Choose default apps by file type.

I just downloaded python on a new pc and now whenever I try to create a script the output viewer just closes down immediately when I launch it as a python file.
My original script was
import secrets
secrets.token_hex(32)
but it just closes down immediately. I thought that it was something with my code so I tried to just make the simple "hello world" script.
(print) "I hope this work"
and I had the same result as the first script, the output window opened up then immediately closed down.
I can get it to work using the python shell but I prefer doing all my coding using notepad++ and it would a real pain in the behind if I can't get that to work.
This is expected behavior if you run your scripts as you described, by opening them in Explorer. Your script completes execution in a terminal window, then closes immediately.
If you absolutely insist on running them on double click and still want to see your console, I suggest you create a .bat file at your python path with contents like this:
python -i %1
and them bind your double-click handler to use that file on .py extension. That way, Python will execute your file and go into CLI mode, preserving your terminal window and allowing you to type further commands.
My other guess would be that you want a console plugin to work right within Notepad++, in that case use nppexec: https://sourceforge.net/projects/npp-plugins/files/NppExec/
What needs to be done?
I need to make a connection to the remote machine through UNIX, go to the shared drive, open an excel file, save it and close it. This needs to written in an script.
The file contains macros so they needs to be opened manually on daily basis, save it and close it. We plan to write a script that would run on daily basis and refresh this file automatically.
Where am i facing the issue?
Making a connection to the remote machine is done, after that i run certains commands:
1. Open the command prompt
2. cd the file path
3. Open the File
Now this is where the issue starts
How to save the file automatically?
How to close that file?
I tried using the taskill option and it almost worked but it gives out the popup of Do you want to save the file and i dont know how to provide output to that popup through command prompt.
Let me know if you have any idea on how to move ahead on this.
A bit hackish, but xdotool, a program which simulates mouse clicks and keyboard presses could be used. If Windows is being used, then see this question for tools which simulate mouse clicks and keyboard presses.
Have you tried SendKeys?
That may help.
I am building a chrome extension where I need to take the text of the current webpage and save that text in the input file on hard disk. This file I need to use in the python program which i'l be running in the back end. This python script will create a output file after processing the input file. Then i'll display this file content on the same webpage in the form of pop up. Now I am need to know how will I create the file,write into it and read from it in chrome. Is there any way to do this???
As far as I know Chrome Extensions are merely glorified javascript snippets. With the limitations of javascript and chrome's sandboxing I doubt you can do File I/O let alone talking to a native application. I'd say the best you can do use Chrome's LocalStorage or WebDatabase APIs. You'll have to poke around to see where these things are actually stored (hacky hacky).
I want to create an image what a web page looks like,
e.g. create a small thumbnail of the html + images.
it does not have to be perfect (e.g. flash /javascript rendering).
I will call use the code on linux, ideally would be some java library, but a command line tool would be cool as well.
any ideas?
Try CutyCapt, a command-line utility. It uses Webkit for rendering and outputs in various formats (SVG, PNG, etc.).
you can get it nearly perfect, and cross platform too, by using a browser plugin.
FireShot or ScreenGrab for Firefox.
6 Google Chrome Screenshot Webpage Capture Extensions
BrowserShots is an open source project that may have some code you can use.

What is the best way to create a web page thumbnail?
Convert HTML to an image
To take a screenshot in the terminal with ImageMagick, type the following line into a terminal and then click-and-drag the mouse over a section of the screen:
import MyScreenshot.png
To capture the entire screen and after some delay and resize it, use the following command:
import -window root -resize 400×300 -delay 200 screenshot.png
You may use a mixture of xwininfo and import to retrieve the window id of the browser and make a screenshot of that window. A bash script to automate this process would be something like this:
#!/bin/bash
window_id=`xwininfo -tree -root | grep Mozilla | awk '{print $1}'`
import -window $window_id -resize 100x100 tumb.png
This script will create a 100x100 screenshot of Firefox on the current directory under the name tumb.png
Several sources show how to run a bash script from inside a Java application, google can help you on that. If you are in a hurry, check this and this.
After reading this page, I was thinking, let me fire up midori browser: http://midori-browser.org/ and when I tried the -h option, I have seen:
-s, --snapshot Take a snapshot of the specified URI
QutyCapt is difficult to compile, and has many dependencies. Midori has it less. It outputs the PNG of the website into TMP folder. One can get the file with:
midori -s http://www.rcdwealth.com new.png 2>/dev/null | awk '{ print $4}'
After that, the file can be converted to thumbnail size by using ImageMagick's convert program.
If you're interested in Java, maybe you could look at browser automation using Selenium-RC http://seleniumhq.com
It's a little java server that you can install on the box and the program itself will execute remote commands in a web browser.
Steps like (this is pseudo code by the way, I code my Selenium in php and I can't recall 100% of the specifics off the top of my head)
selenium.location("http://foo.com")
selenium.open("/folder/sub/bar.html")
selenium.captureScreenshot("/tmp/" + this.getClass().getName() + "."
+ testMethodName + ".png");
Actually, I just did a quick websearch for the exact syntax on that last one ... and this guy has a blog with what might actually be working code in java :)
https://dev.youdevise.com/YDBlog/index.php?title=capture_screenshots_of_selenium_browser_&more=1&c=1&tb=1&pb=1
There's also a number of websites that provide this service "cross browser and OS" I just can't recall what they are. Basically they've got a cloud of every single operating system and browser combination, and they log on with each machine, take a screen and store it on their site for you to come back to in a few hours when they're done.
Ahh... another websearch and it's yours :) http://browsershots.org/
