List Highest Correlation Pairs from a Large Correlation Matrix in Pandas?

Question

How do you find the top correlations in a correlation matrix with Pandas? There are many answers on how to do this with R (Show correlations as an ordered list, not as a lar

Answer 1

Few lines solution without redundant pairs of variables:

corr_matrix = df.corr().abs()

#the matrix is symmetric so we need to extract upper triangle matrix without diagonal (k = 1)

sol = (corr_matrix.where(np.triu(np.ones(corr_matrix.shape), k=1).astype(np.bool))
                  .stack()
                  .sort_values(ascending=False))

#first element of sol series is the pair with the biggest correlation

Then you can iterate through names of variables pairs (which are pandas.Series multi-indexes) and theirs values like this:

for index, value in sol.items():
  # do some staff
