title: how to find and drop correlated columns from pandas df
body: <p>i have a df  that i have used the heat-map to find the correlation between columns, and i want to drop those correlated columns, is there any library or any function which am unaware of to sort this problem?</p>
  <pre><code>import matplotlib.pyplot as plt
  import seaborn as sns
  fig, ax = plt.subplots(figsize=(30,30)) 
  sns.heatmap(dfnew.corr(),annot = True, vmin=-1, vmax=1, center= 0, cmap= 'coolwarm',ax=ax)
