Basic Beginner question

Hi all,

I'm trying to work with a large CSV file to effectively return what a filter would in excel....
So when the value in column 4 = a defined number then return that entire row.
Seems pointless, but some of the csv files won't open with excel as they have too many rows, so this would be quite useful for just looking at 1 customer.
Also, I plan on expanding this a lot further, this is just the 1st step!

What I have so far is:

import csv
import sys


number = '1'

csv_file = csv.reader(open('File.csv', "r", encoding="Latin1"))
filename  = open("Result.csv",'w')
sys.stdout =filename
print(next(csv_file))


for row in csv_file:

    if number == row[4]:
       print(','.join(row))

This is getting me some of the way there, however there are a few cases where cells have ',' within them, this results in the results from here going into 2 different columns.

I was trying to use quotechar="'" but I am using it wrong as my file returns nothing with this.

Also, using the

print(','.join(row))

it changed 'text' to text (which is what I want) however the header row still has 'text'.

Anyone know a good way of fixing these two issues?
Guessing it's quite straight forward, but anything I find online I think I end up using wrong as it returns errors, or it runs but the result file only has the header row, or nothing at all!

Thanks in advance,

N
