Lets say you have generated some html content for a web page dynamically and have it in memory variable in python.
In order to view and test this content, you would need a Python program that prints out the HTML code, which then would have to be copied and pasted to a HTML file, then from there, you can test it in a browser.
In Python, there is a way to launch such HTML code in a web browser so that you don’t have to go through the copy and paste method every time
Suppose you have a list of tuples that looks something like this:
[('abc', 121),('abc', 231),('abc', 148), ('abc',221)]
And you want to sort this list in ascending order by the integer value inside the tuples.
We can achieve this using the
key keyword with
sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda x: x)
key should be a function that identifies how to retrieve the comparable element from your data structure. For example, the second element of the tuple, so we access
Here is a simple code to send mail in Python:
An worker who had left the company had some scripts to automate his life..his coworker has posted this gem to a russian bash.org.
Based on a true story:
xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown… If something – anything – requires more than 90 seconds of his time, he writes a script to automate that.
xxx: So we’re sitting here, looking through his, uhm, “legacy”
xxx: You’re gonna love this
smack-my-bitch-up.sh – sends a text message “late at work” to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login.
kumar-asshole.sh – scans the inbox for emails from “Kumar” (a DBA at our clients). Looks for keywords like “help”, “trouble”, “sorry” etc. If keywords are found – the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply “no worries mate, be careful next time”.
hangover.sh – another cron-job that is set to specific dates. Sends automated emails like “not feeling well/gonna work from home” etc. Adds a random “reason” from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am.
xxx: (and the oscar goes to)
fucking-coffee.sh – this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.
xxx: holy sh*t I’m keeping those
