1. Choosing the Right Libraries for Working with Excel
If Instagram is where your photos come to life,
then Excel is where numbers make sense. Python, in turn, is a fantastic assistant for working with
these "lives" of numbers thanks to the pandas and openpyxl libraries.
Why pandas and openpyxl?
pandas is like your friend who always knows
a shortcut through traffic, making any data handling much easier. It's a library that offers powerful data structures and tools for analysis, making it indispensable
when dealing with tables and other structured data.
openpyxl, on the other hand, acts as
a guide to the world of Excel. It's the go-to library for reading and writing Excel files (.xlsx), and is practically designed to work hand in hand with pandas.
Together, these two libraries are like the Batman and Robin duo of the data world. They work harmoniously to achieve the best results, letting you read, modify, and save Excel files effortlessly.
2. Installing Required Libraries
Step-by-step Guide for Installing pandas and openpyxl
Alright, let's get to work. To install these magical tools, all you need is a "super-complicated" (just kidding) set of commands on your computer. All you'll need at this stage is a terminal. Using
pip, Python's package manager, enter the following commands:
pip install pandas
pip install openpyxl
Don’t forget to say the magic words "Abracadabra"—not mandatory, but it adds drama to the moment.
Verifying Library Installation
After installation, we need to make sure the libraries are properly added to the system. To do this, open the Python interpreter and execute:
import pandas as pd
import openpyxl
If everything went smoothly without errors, congratulations! You're on your way to creating automated Excel masterpieces. If not, check to ensure your virtual environment or Python interpreter is set up correctly.
3. Setting Up the Environment
The libraries you work with often depend on other libraries. When you install one library, all its dependencies are usually installed to make it work right away. However, if you've installed too many libraries, they might bring in conflicting versions of dependencies. These conflicts can cause issues. So it's useful to create a dedicated virtual environment for your project.
Setting Up a Virtual Environment for Managing Project Dependencies
Working with virtual environments is a way to protect your project from the harmful influences of the outside world. You never know when a neighbor library might throw you a surprise in the form of incompatibility. To create a virtual environment, run:
python -m venv myenv
Then activate it. On Windows:
myenv\Scripts\activate
On macOS or Linux:
source myenv/bin/activate
Now you're all set to work in an isolated and safe environment.
4. Practical Applications and Conclusions
Here's a story about a Russian-speaking programmer who automated most of his work processes, including communicating with his wife and brewing coffee. He wrote scripts that sent messages to his wife about being late at work and started the coffee maker at a specific time. This story caught the attention of Western media and became widely discussed online. On his computer after he left, they found some very interesting scripts...
For instance, smack-my-bitch-up.sh sent his wife messages like "Got stuck at work," randomly choosing one of the pre-written reasons. It automatically ran after 9 PM if there were active interactive sessions on his workstation using the ssh protocol and the programmer's login.
And badun.sh on certain dates sent messages to the boss saying “Feeling unwell, will work from home” if the author didn't start working by 8:45 AM. Moreover, he even automated interactions with the “foreign DBA” (database administrator) named Kumar, creating a script
kumar-asshole.sh, which rolled back Kumar's latest actions and automatically replied: “No problem, be careful next time”.
Most of the programmer's former colleagues were surprised that he also automated the coffee-making process. The coffe-blyat.sh script waited around 17 seconds and then sent specific commands to the coffee maker connected to the network.
It was experimentally discovered that [the script]
starts brewing a half-caf chai latte of medium size, which begins pouring into the cup just as the person leisurely walks from his office to the machine.
from the correspondence of the programmer's former colleagues published on bash.im.
Internet users doubted whether there are coffee machines that can be programmed remotely, but commentators found that such devices running Linux indeed exist.
