Cloud9のPython
2021年3月時点では、Cloud9（というかAmazon Linux2）に標準で入っているPythonは、3.79です。
Admin:~/environment $ python -V
Python 3.7.9
SAMでLamdaを書くぞ
SAMでLamdaのコードを書く際に、Runtimeとして、Python3.8を選択できます。
が、インストールされているPythonのバージョンがあっていないため、酷くお叱りを受けます。
Admin:~/environment/sam-app $ sam build
Building codeuri: hello_world/ runtime: python3.8 metadata: {} functions: ['HelloWorldFunction']
Build Failed
Error: PythonPipBuilder:Validation - Binary validation failed for python, searched for python in following locations : ['/usr/bin/python'] which did not satisfy constraints for runtime: python3.8. Do you have python for runtime: python3.8 on your PATH?
Cloud9でPython3.8インストール
セオリー通りに、インストールしようとしますが、残念ながらうまくいきません。
Admin:~/environment/sam-app $ sudo yum install python38
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
229 packages excluded due to repository priority protections
No package python38 available.
Error: Nothing to do
python38 is available in Amazon Linux Extra topic "python3.8"
To use, run
# sudo amazon-linux-extras install python3.8
Learn more at
https://aws.amazon.com/amazon-linux-2/faqs/#Amazon_Linux_Extras
そんなパッケージないと叱られます。
が、ちゃんとヒントが書いてあるので、その通りコマンドを叩きます。
Admin:~/environment/sam-app $ sudo amazon-linux-extras install python3.8

補足
2021年3月現在、LambdaではPython3.9はサポートされてませんが、そもそもPython3.9自体、yumでのインストールに対応していないので、どうしてもCloud9（Amazon Linux2）にインストールしたい場合は、自身でコンパイルするしか方法がなさそうです。
