doing PCA?

[laurentperrinet]

then, scikit-learn may be useful!

pip install scikit-learn

then navigate to :
https://scikit-learn.org/stable/modules/generated/sklearn.decomposition.PCA.html

you need to remove the mean first (of course ;-) )

for this, you can use sklearn.preprocessing.StandardScaler with the with_std=False option
