How to write a file in azure function app in python?

Question

I am creating a azure function. This function locally have a csv file. I read it via given code

csv = f'{context.function_directory}/new_csv.csv'
df=pd.read_csv(csv)

after reading the data, I want to make some changes to this csv (like adding some columns). Please suggest some code how can I write this updated csv/dataframe in same directory and with the same name.

D.L · Answer

you just have to write back to the same file (or a new file)...

csv = f'{context.function_directory}/new_csv.csv'
df=pd.read_csv(csv)

# make edits to the dataframe

make a new csv or write to existing csv

df.to_csv()
