This is under your control usually so you do not need to check for python to be installed.

You might check for enough disk space before starting to ensure that you can write the results, again this is usually under your control.

But you do not control the internet as an end user.
As it is not under your control you have to code to survive its failure modes.
For example email delivery is retried until the MTA gives up or succeeds.

Check before you start. But you are going to notice people attempting to take goal posts away while you play.

Since you have to deal with things that you do not control changing after you check what is the point in checking? You have to write the code to recover anyway.
