BelenCebrian / python-projects

A collection of several short Python projects, used for scraping several websites at once or monitoring things, and notify changes via Telegram messages.

Python 3 projects

What you will find here: short Python 3 projects that I use everyday, sorted into folders.

Mainly to monitor things and keep me informed using Telegram messages.

And it's usually run in a Raspberry Pi device I have always on :)

Files Operations

Merge PDFs

It’s used to merge independent PDF files into a single document. Useful when each file is frequently updated and is in a different location. By using shortcuts to each file, you avoid searching or moving them from their respective folders.

How it works:

1. Create shortcuts to each PDF you want to merge in the same location where the script is located.

2. Execute the Python script in a terminal python merge_pdfs.py.

3. When the merge operation is finished, the final PDF (called Result.pdf) should launch in your default PDF viewer.

Terminal output:

Webmonitor

It's a messy scrapper to keep track of certain projects, and message me when they are updated. It's not intended to be pretty or pythonic, just useful.

How it works:

1. The script (webmonitor.py) is launched at the same hour every day via a cron job.

2. It dumps today scrapped data into a file (versiones.txt) and later compares it to yesterday data (b-versiones.txt)

3. If a change it's detected (the comparision between the files is done line-by-line) the changes are being sent via a Telegram message.

It keeps track of: Android-x86, ASUS RT-68U firmware, Calibre, LibreOffice, Inkscape and more.

Speedmonitor

It's used to check how fast are my Internet speed from hour to hour. Making a nice graph with the data it's a nice way to keep track of changes. Currently just to keep me informed, but I plan to add notifications to get informed when it descends below a certain value.

How it works:

1. Do a speedtest every hour and log the results into a csv file (speedmonitor.py).

2. At a later time, make a graph with matplotlib and send it via Telegram's bot (graph.py).

3. At last, a script to keep everything organized when yesterday's data are not longer needed (move.py).

cron is used to launch the scripts at the appropiate time. For example, in case of speedmonitor.py the crontab file has this line (it means it's executed every hour):

0 * * * * python3 $HOME/scripts/speedmonitor/speedmonitor.py

Example of the graph generated:
