CalPlot.py

import calplot
import numpy as np; np.random.seed(sum(map(ord, 'calplot')))
import pandas as pd
all_days = pd.date_range('1/1/2019', periods=730, freq='D')
days = np.random.choice(all_days, 500)
events = pd.Series(np.random.randn(len(days)), index=days)
calplot.calplot(events)

Executing python program:

$ python CalPlot.py 
Traceback (most recent call last):

ModuleNotFoundError: No module named 'calplot'

Any suggestions?

>Solution :

The keyword python is usually associated with the default version of python installed on your system. If you are using a Linux distro or Mac, this most likely python 2.7.

It therefore means you probably have two versions of python on your system. In this case you will need to be specific on the version of python associated with the library you installed. SO modify your command:
