NLP project, python or C ++

Question

We are working on a project to process Arabic in natural language, we limited our choice to writing code in Python or in C ++ (and in the Boost library). We think about these points:

• Python

  • Slower than C ++ (work continues on creating Python)
  • Improved UTF8 Support
  • Speeding up test writing and using different algorithms

• C ++

  • Faster than python
  • Familiar code, every programmer knows C or C code

After the project is completed, transferring the project to other programming languages ​​should not be very difficult.

What do you think is best and suitable for the project?
