saving data from text file to CSV file in python having delimiter as space

[K11]

I have a huge report file. I extracted the required data from it into a new file named "new.txt" I want to save this data in a csv file so that i get the columns and rows properly for each of the headers defined in the file. I am posting my code and the text file contents here...I am not able to get it in the proper form as we get it in excel. Kindly help..I am using python 2.7 and want to do this without using pandas package.

SIMPLE_FILE REPORT:

Output:
CALL            Alias           Severity   File                                                                                                                                                             Line   Wt   Message

Here is my code.

import csv

outFile = "new.txt"
new_file = open(outFile, "a+")
new_file.truncate(0)
csv_file = "report.csv"
    
def open_file(filename):
    try:
        contents = [] 
        with open(filename, 'r') as f1:
            contents=[line.strip() for line in f1]
        counter = contents.index("Final report:")
        for item in contents[counter:]:
            new_file.write(item+"\n")

        in_txt = csv.reader(new_file, delimiter = '\t')
        out_csv = csv.writer(open(csv_file, 'w'))

        out_csv.writerows(in_txt)
    except Exception,e:
        print str(e)
    exit(1)
