Python installing as 32bit application on my 64bit system

[DeaD_EyE]

Is there any issue with this or will the running of code be affected in any way?

Not direct. Windows and the most Linux distributions have 32 bit and 64 bit libraries installed.
I guess float have the double accuracy in 64 bit.

If you want to install extensions like numpy manually (the unofficial binary distribution), you've to chose the same architecture + supported Python Version.

If you go a deeper and want to use C libraries with ctypes or cffi, the Interpreter must have the same architecture (32/64 bit) to access this libraries.

For a beginner this does not matter.
