Export Python variables and import them into your LaTeX document -- Combining Python with LaTeX
Do you have a dataset in Python that you want to include in your LaTeX document? In this video, I'll show you how to import Python variables into your LaTeX document in a simple and efficient way using the datatool package and filecontents.
We'll start by creating a Python script that generates a dataset, and then we'll use the filecontents package to save it to a file. Next, we'll use the datatool package to read the dataset from the file and create a database in LaTeX. Finally, we'll use the database to display the dataset in a table in our LaTeX document.
Whether you're a researcher, a student, or a data analyst, this technique can save you time and effort by allowing you to easily include your Python data in your LaTeX documents.
Join me in this tutorial and learn how to import Python variables into your LaTeX documents in just a few simple steps!

📝 Useful notes:
To save a variable in Python: save_var_latex("variable_name", 22)
To import a variable in LaTeX: \var{variable_name}
👨💻 Source code:
```python
def save_var_latex(key, value):
import csv
import os
dict_var = {}
file_path = os.path.join(os.getcwd(), "mydata.dat")
try:
with open(file_path, newline="") as file:
reader = csv.reader(file)
for row in reader:
dict_var[row[0]] = row[1]
except FileNotFoundError:
pass
dict_var[key] = value
with open(file_path, "w") as f:
for key in dict_var.keys():
f.write(f"{key},{dict_var[key]}\n")
```
```latex
% package to open file containing variables
\usepackage{datatool, filecontents}
\DTLsetseparator{,}% Set the separator between the columns.
% import data
\DTLloaddb[noheader, keys={thekey,thevalue}]{mydata}{../mydata.dat}
% Loads mydata.dat with column headers 'thekey' and 'thevalue'
\newcommand{\var}[1]{\DTLfetch{mydata}{thekey}{#1}{thevalue}}
```
