Principle Component Analysis for computer science code example

Example: pca

#if required,do pca 1st 
#then outliers removal then skewness removal

from sklearn.decomposition import PCA
pca=PCA(n_components=20)
pca.fit(df)
x_pca=pca.transform(df)
print(x_pca.shape)
x_pca20=pd.DataFrame(data=x_pca)
