I recently came across corrmorant package in R.

It allows to plot all three basic EDA plots together: Scatter Plot + Histogram + Correlation Values. enter image description here

Is it possible to do same in Python also?

Corrmorant is based on ggplot, but it seems that there is no equivalent in Python.

However, you can redo it thanks to this code:

import matplotlib.pyplot as plt
from scipy import stats
import seaborn as sns
import numpy as np

def corrdot(*args, **kwargs):
    corr_r = args[0].corr(args[1], 'pearson')
    corr_text = round(corr_r, 2)
    ax = plt.gca()
    font_size = abs(corr_r) * 80 + 5
    ax.annotate(corr_text, [.5, .5,],  xycoords="axes fraction",
                ha='center', va='center', fontsize=font_size)

def corrfunc(x, y, **kws):
    r, p = stats.pearsonr(x, y)
    p_stars = ''
    if p <= 0.05:
        p_stars = '*'
    if p <= 0.01:
        p_stars = '**'
    if p <= 0.001:
        p_stars = '***'
    ax = plt.gca()
    ax.annotate(p_stars, xy=(0.65, 0.6), xycoords=ax.transAxes,
                color='red', fontsize=70)

sns.set(style='white', font_scale=1.6)
iris = sns.load_dataset('iris')
g = sns.PairGrid(iris, aspect=1.5, diag_sharey=False, despine=False)
g.map_lower(sns.regplot, lowess=True, ci=False,
            line_kws={'color': 'red', 'lw': 1},
            scatter_kws={'color': 'black', 's': 20})
g.map_diag(sns.distplot, color='black',
           kde_kws={'color': 'red', 'cut': 0.7, 'lw': 1},
           hist_kws={'histtype': 'bar', 'lw': 2,
                     'edgecolor': 'k', 'facecolor':'grey'})
g.map_diag(sns.rugplot, color='black')
g.fig.subplots_adjust(wspace=0, hspace=0)

# Remove axis labels
for ax in g.axes.flatten():

# Add titles to the diagonal axes/subplots
for ax, col in zip(np.diag(g.axes), iris.columns):
    ax.set_title(col, y=0.82, fontsize=26)
