Before installing python on the Linux platform, you may have to install zlib package,

if any permission issue, then 
$ sudo yum install zlib-devel
Download python releases from python.org, you can choose the release version according to your need

$ wget https://www.python.org/ftp/python/3.8.6/Python-3.8.6.tgz
unzip the downloaded file using the following command
$ tar xf Python-3.8.6.tgz
Change the directory to python directory

 $ cd Python-3.*
run the ./configure tool to prepare the build 
$ run the ./configure tool to prepare the build
now using make command , start to build python
$ make
finally you can install python using the below command,
$ make install

if you face any permission issue, then use sudo 

$ sudo make install

If you need to run multiple python releases in your platform, you have to use the below command, so it will not overwrite the existing python release
$ make altinstall
$ vim helloworld.py

# helloworld program
print('Hello world')

press “esc” and type 😡 (save and exit)

now execute the python code

$ python helloworld.py
