FIELDNAMES throwing an error?

for some reason I'm getting an error when I try to run my code in the workspace. it's saying that there's a sytax error with the variable "FIELDNAMES" I can't seem to find what it's talking about. 

import csv
import numpy

def open_with_csv(filename, d='\t'):
  data = []
  with open(filename, encoding='utf') as tsvin:
    tie_reader = csv.reder(tsvin, delimiter='\t')
    for line in tie_reader:
      data.append(line)
  return data


data_from+csv = open_with_csv('data.csv')
print(data_from_csv([0])

FIELDNAMES = ['', 'id', 'priceLabel', 'name', 'brandId', 'brandName', 'imageLink', 'desc', 'vendor', 'patterned', 'material']

DATATYPES = [('myint', 'i'), ('myid', 'i'), ('price', 'f8'), ('name', 'a200'), ('brandId', '<i8'), ('brandName', 'a200'), ('imageUrl', '|S500'), ('description', '|S900'), ('vendor', '|S100'), ('pattern', '|S50'), ('material', '|S50'), ]

def load_data(filename):
      my_csv = numpy.genfromtxt(filename, delimter=d, skip_header=1, invalid_raise=False, names=FIELDNAMES, dtype=DATATYPES)
      return my_csv

my_csv = load_data('data.csv')"""

Hi Charlesdi

I cannot see anything wrong with the FIELDNAMES variable, although there are a few other errors in you code 

data_from+csv=open_with_csv('data.csv')

# should be

data_from_csv=open_with_csv('data.csv')

# you have not passed in the delimiter to the function
def load_data(filename,d='\t'):
  my_csv=numpy.genfromtxt(filename,delimiter=d,skip_header=1,invalid_raise=False,names=FIELDNAMES,
                                      dtype=DATATYPES)
      return my_csv

Gotcha, thanks! I've made the changes to the code. I've decided to just write the code in a jupyter notebook. This way I'll be able to reference it later and upload it to github as well. It's unfortunate that I'm missing out on things such as actually executing the script and navigating the file system, but I'll live.
