Can't paste value of re.findall in cell using openpyxl - python-3.x

Question

I'm unable to print the result of re.findall in an Excel cell, which is the result of another re.findall which is captured from a text file with multi-line data.
Below is the section of code from the entire code where I am facing a problem.
import openpyxl,os,re # -- Import
pyro_asr920_dir = '{}\\'.format(os.getcwd()) # -- MARK DIRECTORIES
input_asr920_robot_pid_wb = openpyxl.load_workbook('Data_Workbook.xlsm', keep_vba = True) # -- OPEN EXCEL
input_asr920_robot_pid_tpd_sheet = input_asr920_robot_pid_wb['Topology-Ports_Details']
wduplinka = open(os.path.join(pyro_asr920_dir, 'DELSNACAG01C7606-logs.txt'),'r') # -- OPEN MULTILINE TEXT FILE
uplinkacontent = wduplinka.read()
PreBBa = re.findall( r'{}[\s\S]*?!\ni'.format('interface TenGigabitEthernet4/2'), uplinkacontent) # -- GET REQUIRED SUBSTRING WITH MATCH CRITERIA IN BETWEEN
print(PreBBa)
output01 = '''
['interface TenGigabitEthernet4/2\n isis metric 10 level-2\n!\ni']'''
for line in PreBBa: # - 01 > I CAN PRINT THIS ON EXCEL CELL
input_asr920_robot_pid_tpd_sheet['H27'] = line[:-1]
print(line[:-1])
print('-----------')
output02 = '''
interface TenGigabitEthernet4/2
isis metric 10 level-2
!'''
# ----------------------------------------------------------------- UNABLE TO GET VALUES IN CELL
for line in PreBBa: # - 02 > I CAN'T PRINT THIS ON EXCEL CELL {THIS IS WHERE I AM STUCK}
if 'ospf' in line:
theOSPF = re.findall(r'{}[\s\S]*?{}'.format(' ip ospf','\n c'), line)
input_asr920_robot_pid_tpd_sheet['C47'] = 'Yes'
else:
input_asr920_robot_pid_tpd_sheet['C47'] = 'No' # UNABLE TO GETRESULT IN EXCEL
output03 = '''No'''
# -----------------------------------------------------------------
metric = re.findall(r'{}[\s\S]*?{}'.format('metric ',' '), str(line))
metric = re.findall(r'\d+',str(metric))
input_asr920_robot_pid_tpd_sheet['C46'].value = metric[0] # UNABLE TO GETRESULT IN EXCEL
print(metric)
output04 = '''10'''
# -----------------------------------------------------------------
input_asr920_robot_pid_wb.save('Data_Workbook.xlsm')
wduplinka.close()
input_asr920_robot_pid_wb.close()
print('TEST COMPLETED')
