1. Go to the Python Download page. https://www.python.org/downloads/release/python-3130/

Download the Gzipped source tarball.

2. Extract the tgz file into a folder

tar -xvf Python-3.13.0.tgz

3. Before start installing the Python, install the system-level dependencies and packages

sudo apt update
sudo apt install -y build-essential libffi-dev libsqlite3-dev zlib1g-dev \
    libreadline-dev libbz2-dev liblzma-dev libncursesw5-dev libgdbm-dev \
    libssl-dev libdb-dev uuid-dev tk-dev

4. Now install the Python. Go to the extracted directory Python-3.13.0 and run these commands in order. This will take some time.

./configure --enable-optimizations --with-system-ffi --with-computed-gotos \
    --enable-loadable-sqlite-extensions --enable-shared --prefix=/usr/local

without --enable-loadable-sqlite-extensions option you might get the below error while using code related to panda/MySQL/SQLite.

ModuleNotFoundError: No module named '_sqlite3'

Continue with below commands

make
make test
sudo make install

5. Now verify the installation by invoking the python3 or python3.13 interpreter.

6. If you get the below error

./python3: error while loading shared libraries: libpython3.13.so.1.0: cannot open shared object file: No such file or directory

It means the system cannot locate the shared library (libpython3.13.so.1.0). This happens because we enabled shared libraries with --enable-shared during configure, but the system’s dynamic linker doesn't know where to find them.

Fix this error by running the below command

echo "/usr/local/lib" | sudo tee -a /etc/ld.so.conf.d/python3.13.conf
sudo ldconfig

Explanation:

Temporary Fix (Session Only)

If you need a quick fix without modifying system files, export the library path manually:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

Note: This change is temporary and will reset when you close the terminal. Add it to your ~/.bashrc or ~/.profile if you want it to persist. 

7. Create a virtual environment

virtualenv -p /usr/local/bin/python3.13 venv-name

activate it and install the dependencies.
