Error while parsing tables from docx file

[aditi]

I see, does this make it better?
The input file:

My Document = some_doc.docx

import os
import re
from docx import Document

f = open("sometext.txt", "w")
def get_inputs():
    global my_doc, my_doc_file

    input_file = open('input.txt','r')                     #reading inputs text file
    names = input_file.readlines()
    input_file.close()
    for i in range(0,len(names)):
        if re.search(r'My document',names[i],re.IGNORECASE):
            pos = str(names[i]).rfind("=")
            my_doc = str(names[i][pos+1:]).strip()
    if os.stat(my_doc).st_size == 0:                       #checking the size of my_doc, if zero then message displays
        print("Empty Document! Please check and retry!")    
    my_doc_file = Document(my_doc)                         #reading the .docx file, throws error if it does not exist
    print(my_doc, my_doc_file)


def extract(my_doc):
    tlist = []
    tab_list = []
    #global my_doc, my_doc_file
    for table in my_doc.tables:                                        #looping through all tables in the .docx file
        if re.search("mystring", table.cell(0,1).text, re.IGNORECASE):            
            for row in table.rows:                                  #looping through all rows in the table under consideration
                for cell in row.cells:                                  #looping through all cells(grid cells are considered, not actual) in the row under consideration
                    tabdata = cell.text
                    tabdata = re.sub(r'\s+',"",tabdata)                     #cell.text is the text in each cell
                    tlist.append(tabdata)                               #appending to tlist(tlist is a list/array) a list of all the text in a row
                tab_list.append(tlist)                                  #list of all rows
                tlist = []
            f.write(tab_list)                                  
            tab_list=[]

def main():
    global my_doc, my_doc_file
    get_inputs()
    extract(my_doc_file)
    print("DONE!")

main()

and the error is:
