Convert list to interger

[Clives]

Greetings,
The csv returns: [114436]
I want to get the values as an integer and not list, any pointers appreciated.
Thanks
Clive

##### CSV
id = open(manhole, encoding='utf-8' )
manhole_id = csv.reader(id)
next(id, None)

rows = ()
for row in manhole_id:
    data_manhole_id = [int(item) for item in row]
    print(data_manhole_id)

I still get:

Output:
[114436]
[114474]
[114514]

Not

Output:
114436
114474
114514

I also get an error: TypeError
TypeError: list indices must be integers or slices, not list

I assume your file looks like this:
114436
114474
114514

This is not csv format. You do not need a CSV reader.

with open("data.csv", "r") as file:
    for line in file:
        print(int(line))

What you wrote is for data that is actually in csv format
114436,114474,114514

import csv

with open('data.csv', "r") as file:
    reader = csv.reader(file)
    for row in reader:
        data = [int(item) for item in row]
    print(data)

Output:
[114436, 114474, 114514]

Hi Dean,
Thanks for the advice.

I changed the code:

        line = ()
        with open(data,  encoding='utf-8') as manhole_id:
            #csv_reader = reader(manhole_id)
            for line in manhole_id:
                next(manhole_id, None)

The next(manhole_id, None) is not working??
It is returning an extra line??

Thanks
Clive

If the file looks like this:
Whatever
114436
114474
114514

You can skip the first line in the file.

with open("data.csv", "r") as file:
    next(file)
    for line in file:
        print(int(line))

Output:
114436
114474
114514

When using a contact manager (with), the file only remains open for code that is in the context block (indented 1 level deeper than the with). In your latest example the manhole_id file is closed before the for loop executes.

Apologies typo...

It returns:
114806

114810

114831

114841

114843

NOT:
114806
114810
114831
114841
114843

You are doing something wrong. My guess is you are printing the str which has a trailing linefeed. I thought you wanted to read the file and convert to int.
