Why is csv not defined?

Jake 1986 :

I am trying to do a relatively simple parse of a csv file, and I don't understand why the csv module is not working. Here is my code:

import csv

def getFromCSV(fileName):
    with open(fileName, 'r') as f:
        reader = csv.reader(f)
        data = list(reader)
    return data

def append_row(fileName, my_list):
    with open(fileName, 'a') as output:
        writer = csv.writer(output)
        writer.writerow(my_list)


data = getFromCSV('dh_internal_all.csv')

for row in data:
    if '25252' not in row:
        print(row)
        append_row('parsed.csv',[row])

This returns:

dh-dfbhv2l:Documents jwr38$ python3 remove_bad_data.py 
Traceback (most recent call last):
  File "remove_bad_data.py", line 13, in <module>
    data = getFromCSV('dh_internal_all.csv')
  File "remove_bad_data.py", line 3, in getFromCSV
    reader = csv.reader(f)
NameError: name 'csv' is not defined

Thank you in advance for any tips.

EDIT: when I run python3 in terminal, then import csv, and then csv, it seems to recognize it, it returns:

<module 'csv' from '/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.7/lib/python3.7/csv.py'>

You pasted the wrong code. In your traceback, the faulting line is 3, but in this code, it's 5 - the two missing lines are probably the "import csv" lines.
