[New-bugs-announce] [issue35626] Python dictreader KeyError issue

[Eduardo Orochena]

New submission from Eduardo Orochena <mint.alchemist at gmail.com>:

def load_file(filename):

    with open(filename, 'r', encoding='utf-8') as fin:
        header = fin.readline()
        print('Found ' + header)

        reader = csv.DictReader(fin)

        for row in reader:
            print(type(row), row)
            print('Beds {} '.format(row['beds']))

This results in a KeyError exception

whilst 

open_f = open(filename, 'r', encoding='utf-8')

    read_it = csv.DictReader(open_f)

    for i in read_it:
        print('Beds {}'.format(i['beds']))

behaves as expected
