Want to know if I can access the second to last row of this csv file? Am able to access the very last using:
pd.DataFrame(file1.iloc[-1:,:].values)
But want to know how I can access the one right before the last?
Here is the code I have so far:
import pandas as pd
import csv
url1 = r"https://raw.githubusercontent.com/owid/covid-19-data/master/public/data/vaccinations/country_data/Austria.csv"
file1 = pd.read_csv(url1)
df1 = pd.DataFrame(file1.iloc[:,:].values)
df1 = pd.DataFrame(file1.iloc[-1:,:].values)
Austria_date = df1.iloc[:,1]
Austria_cum = df1.iloc[:, 4].map('{:,}'.format)
if ( Austria_cum.iloc[0] == 'nan' ):
Essentially I am checking if the the row at that specific col is 'nan', which is True, and after which I want to get the data from the row right before the last. Please, how would this be done?
Thank you
As simple as that:
df1.iloc[-2,:]
To access the data frame at any index you can use the following
df.iloc[i]
For your ask you need to set the index as -2, which would look like this:
df.iloc[-2]
Just use negative indices like in your example, but pull out the second to last with -2
instead of the last:
df.iloc[-2,:]
