Scipy - statistical tests between two groups

Question

I have two samples from the population of neurons in the brain, each sample consisting of a thousand neuron instances, of categories:

1. cerebellum
2. cortex

Now I'm extracting multiple metrics for each sample using complex network analysis, for example, neuron degree of connectivity k, a discreet number n = 0, 1, ...., n, or clustering coefficient C, a continous value between 0.00000 and 1.00000.

df.sample(3) (where web is category) in my pandas dataframes:

cortex:

         web    k   clustering_coeff
3080    cortex  6.0         0.733333        
2951    cortex  11.0        0.428571    
1435    cortex  5.0         0.563571    

...

cerebellum

815 cerebellum  10.0        0.533333    
850 cerebellum  9.0         0.416667    
1213 cerebellum 7.0         0.454545
...

How can I use scipy stats methods to I compare both metrics in order to know if theres a statistically significant difference between the two gropus?

Assuming a distribution close to Gaussian, but skewed to the right, I'm not sure what is the best approach. Parametric, Non-Parametric, T-test and so on.

Any ideas?
