First check for all the python version available to install using conda search python. It will give list like below.

# Name                       Version           Build  Channel             
python                        2.7.13     hac47a24_15  pkgs/main           
.
.
.
python                         3.8.2      h191fe78_0  pkgs/main           
python                         3.8.2      hcf32534_0  pkgs/main           
python                         3.8.2     hcff3b4d_13  pkgs/main           
python                         3.8.2     hcff3b4d_14  pkgs/main           
python                         3.8.3      hcff3b4d_0  pkgs/main           
python                         3.8.3      hcff3b4d_2  pkgs/main  

Then, install the latest version using conda install python=3.8.3.
