How to delete specific lines of a text file using python ?

Question

python geeks

Answer 1

f = open("file", "r+")
delete = 2
count = 0

for line in f:
count++
if(count != delete):
f.write(line);
f.write("\n");

Untested but should work.
At least you get the idea.

Answer 2

i guess read the file, save all lines as String elements of an array.

modify the array as you wish (add/remove/edit lines/ elements).

and overwrite your file with a new one containing every line of your array.
