How do I make it so when I insert a row to csv it adds it to another line

Question

So I'm trying to insert a new row to a csv file using pandas. It adds the data, but it doesn't make it into a new row for example

This is the current file:

id,balance
00,100

But when I insert a new row, it becomes like this:

id,balance
00,10001,0

I have tried adding \n to the id but it becomes like this:

id,balance
00,100"
01",0

This is my current code:

member_id = '\n' + str(member.id)
df1 = pd.DataFrame({
     'id': [member_id], 
     'balance': [0]
})
     df1.to_csv('member_file.csv', mode = 'a', header = False, index = False)

How do I make it so it adds it to another line?

Answer 1

Add a newline at the end of the file (before you call to_csv ) with:

with open('member_file.csv', "a") as myfile:
    myfile.write('\n') 

Answer 2

use pd.DataFrame.append()

df1 = pd.DataFrame.append({
     'id': [member_id], 
     'balance': [0]
})
df1.to_csv('member_file.csv', mode = 'a', header = False, index = False)
