You have to register for an Account and get an API Key to access FRED data.

II. The scripts

Here are the scripts for Google Colaboratory:

!pip install fredapifrom fredapi import Fred
from calendar import month
from fredapi import Fred
import dateutil.parser as dp
import matplotlib.pyplot as plt
import datetime

fred = Fred("YOUR_API_KEY")

start_date = dp.parse('2012-01-01')
ukraine_war = dp.parse('2022-02-24')

cpi_mom = fred.get_series('JPNCPIALLMINMEI')
cpi_mom = cpi_mom[cpi_mom.index > start_date]

plt.figure(figsize=(12,8))
plt.plot(cpi_mom)
plt.axvline(ukraine_war,c='red')
plt.text(ukraine_war+datetime.timedelta(days=-1500),102.8
         ,'Russia invaded Ukraine \n On 24 Feb 2022    -->'
         ,fontsize=20)
plt.text(ukraine_war+datetime.timedelta(days=-2400),100.8
         ,'Consumer Price Index \n started going up in Apr 2021 -->'
         ,fontsize=20)
plt.show()
