How to plot these histograms next to each other-CodePudding

I want to take a look onto data distribution. Problem is I want to make loop that displays each dataframe column separately. With this approach every column's histogram is plotted on one graphical area.

for x in df.columns.to_list():
  df[x].hist(bins=120)

How to divide these histograms to separated images?

Having sample data with 3 columns:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

d = {'col1': [1, 2, 3, 4, 5, 6, 3, 5], 
     'col2': [1, 2, 2, 2, 5, 6, 3, 5], 
     'col3': [1, 2, 2, 2, 2, 2, 2, 6], }
df = pd.DataFrame(data=d)

df

You can use subplots from matplotlib to see each column on separate histogram:

fig, axs = plt.subplots(len(df.columns), figsize=(8,12))
i=0

for x in df.columns.to_list():
    axs[i].hist(df[x], bins=10)
    i=i 1

Why not just df.hist(bins=120) ? No need to go through the loop.
