Python is a scripting language. It allows me to develop a right answer in record devopment time and with a high degree of confidence that the result does what it needs to do. If, then, there are speed problems then I can optimise my existing code or rewrite sections in other languages, but crucially use my initial code to aid in testing the more obscure rewrites. Most of the time, some thought upfront will tell you if you will need a compiled solution early on, but even then - getting it correct in Python before getting it fast in something like C++ can be faster - the spec is often revised as implementation can change specsand Python is more agile.

Execution speed is more than execution speed - you need to be correct, and being fast enough is quality; faster may be wasteful.
