I have a folder with nearly 150 *.txt files. I need to delete the 1st seven lines of every .txt file in that folder using python3.5.2

What does your folder structure look like? You need to loop through each file and then do what is mentioned in the link I’ve given. — Jack Moody, Dec 05 '18 at 20:27

You can use Python's OS Module to get the names of all *.txt files from your folder. Then you can iterate over this names, read all lines from each file and overwrite the file with the lines you want to keep:

from os import listdir, path

path_str = '.'  # your directory path
txts = [f for f in listdir(path_str)
        if f.endswith('.txt') and path.isfile(path.join(path_str, f))]

for txt in txts:
    with open(txt, 'r') as f:
        lines = f.readlines()

    with open(txt, 'w') as f:
        f.write(''.join(lines[7:]))
