Install Python 3.8 on SLE Micro 5.5

1. Login as root user

   $ sudo -i

2. Open up a transactional-update shell session

   $ transactional-update shell

3. install the necessary interdependent software packages

   $ zypper install zlib-devel make gcc

4. Download the python from www.python.org

   $ curl -sO https://www.python.org/ftp/python/3.8.20/Python-3.8.20.tgz

5. Unzip it and Go to the folder

   $ tar zxfv Python-3.8.20.tgz && \
     cd Python-3.8.20/

6. Make a directory where you want to put your python. I called my .localpython3.8 (name it whatever you want) and make it under the home directory. Configured the Python make

   $ mkdir /root/.localpython3.8
   
   $ ./configure --prefix=/root/.localpython3.8

7. Make and make altinstall (see difference between install and altinstall here)

   $ make
   
   $ make altinstall

8. Exit the transactional-update session and reboot to the new snapshot that contains the changes you have made

   $ exit
   
   $ reboot

9. Login as root user again

   $ sudo -i

10. configure PATH env and alias

    $ cat <<'EOF' >> /root/.bashrc
    export PATH=/root/.localpython3.8/bin:$PATH
    EOF
    
    $ cat <<'EOF' >> /root/.alias
    alias python=/root/.localpython3.8/bin/python3.8
    EOF
    
    $ exit
    
    # Login again
    $ sudo -i

11. 寫一個簡單的程式快速測試

    $ cat <<'EOF' > test.py
    message = "Hello, World!"
    print(message)
    
    numbers = [1, 2, 3, 4, 5]
    
    for num in numbers:
        print(num)
    
    def add_numbers(x, y):
        return x + y
    
    result = add_numbers(2, 3)
    print(result)
    
    import datetime
    
    now = datetime.datetime.now()
    formatted_date_time = now.strftime("%Y-%m-%d %H:%M:%S")
    print(formatted_date_time)
    EOF

12. 執行測試程式

    $ python test.py

    執行結果如下 :

    Hello, World!
    1
    2
    3
    4
    5
