Using Python: How to divide two different indicators (amount and exchange rate) in case two attributes match (Country AND date)?

I downloaded and imported a csv file from an economics research database which contains three columns (screenshot of the table): "Country-Code", "Time", "Indicator". There are basically two types of indicators (1. amount in local currency and 2. EUR exchange rate). How can I create a new column "EUR_amount" in Python that divdes the amount with the rate in case the countrycode and the month is the same for both items, e.g. EUR = amount/rate where country and time matches?

Any help highly appreciated! (Please keep in mind that I am quite a noob with python and this is my first question on stackoverflow ever.) Thanks a lot in advance.

Edit: Adding this code after receiving feedback from mozway (thanks for that):

import pandas as pd
df = pd.DataFrame({'country_code':['EU','UK','US','EU','UK','US','EU','UK','US','EU','UK','US','EU','UK','US','EU','UK','US'],
               'date':['2019-03','2019-03','2019-03','2019-04','2019-04','2019-04','2019-05','2019-05','2019-05','2019-03','2019-03','2019-03','2019-04','2019-04','2019-04','2019-05','2019-05','2019-05'],
              'item':['exposure','exposure','exposure','exposure','exposure','exposure','exposure','exposure','exposure','FX-rate','FX-rate','FX-rate','FX-rate','FX-rate','FX-rate','FX-rate','FX-rate','FX-rate'],
              'value':[15000,9000,13000,16500,8750,17000,17000,7999,25000,1.00,1.25,0.90,1,1.23,0.93,1.00,1.24,0.95]})
print(df)

So, to restate my question: How can I divide the item exposure with the item FX-rate under the condition of country_code AND date are matching?
