Perhaps you should try some spelling variations:
equations python » equations without (Expand search), equations photons (Expand search), equations non (Expand search)
python using » python coding (Expand search), python usando (Expand search), action using (Expand search)
using python » usando python (Expand search), in python (Expand search)
code python » codigo python (Expand search), pacote python (Expand search)
