我正在尝试迭代这个1D数组以获取所有8位数字中的所有数字，但我不确定如何

Question

在这里，我将文本文件移至数组，只需要访问此数组的特定8位元素即可。

os.chdir(r'C:\Users\nicho\Downloads')
cik = '0001065280'
cik_nums = []

with open('bd040122.txt', 'r') as f:
    for line in f:
            cik_nums.append(line)
               
base_submissions_url = r'https://data.sec.gov/submissions/CIK' + cik + r'.json'

content = requests.get(base_submissions_url, headers=header)
decoded_content = content.json()

submissions_json_file = open(r'sec_' + cik + r'.json', 'w')
json.dump(decoded_content, submissions_json_file, indent=3)

with open(r'sec_' + cik + r'.json') as sec:
    submissions_mass = json.load(sec)

array = np.array(str(cik_nums).split('\\t'))
array1 = array[1:-1]
array1[:20]

输出：

       '3724 47TH STREET CT. NW', ' ', 'GIG HARBOR', 'WA', '98335',
       "\\n', '\\n', '0000002303", 'PROSPERA FINANCIAL SERVICES, INC.',
       '00828164', '5429 LBJ FREEWAY', 'SUITE 750', 'DALLAS', 'TX',
       '75240', "\\n', '\\n', '0000002554", 'AEI SECURITIES, INC.',
       '00816750', '1300 WELLS FARGO PLACE', '30 SEVENTH STREET EAST'],
      dtype='<U56')

我希望有这样的列表： ['00828164'，'00829452'，...]
