在 Pandas Python 中添加一行并将值附加到列

Question

I am trying to append 10, 5, 890, 50, Finish for the Date,High,Low,Volume,Symbol at the end of the input.csv file. It will format the contents of the csv file permanently so I use data.to_csv(url,index=False) . How would I be able to do that?

import pandas as pd
url= 'input.csv'
data = pd.read_csv(url, low_memory=False)
data.to_csv(url,index=False)

Current output:

Date,High,Low,Volume,Symbol
2021-01-15 00:04:00,39358.98,39273.24,0.4786072902,BTCUSD
2021-01-15 00:03:00,39362.37,39166.19,0.2911817448,BTCUSD
2021-01-15 00:02:00,39187.06,39017.72,6.2488076695,BTCUSD

Expected output:

Date,High,Low,Volume,Symbol
2021-01-15 00:04:00,39358.98,39273.24,0.4786072902,BTCUSD
2021-01-15 00:03:00,39362.37,39166.19,0.2911817448,BTCUSD
2021-01-15 00:02:00,39187.06,39017.72,6.2488076695,BTCUSD
10 , 5, 890, 50, Finish 

Answer 1

Try with loc :

data = pd.read_csv(url, low_memory=False)

data.loc[len(data)] = [10 , 5, 890, 50, 'Finish' ]
data.to_csv(url,index=False)
