Doing calculation with ascii file

[Mike]

I guess I solved my problem.
Here is the script:

with open('file.txt',"r") as in_file, open('file2.txt',"w") as out_file:
	next(in_file)
	for line in in_file:
		line = line.strip()
		num1, num2 = line.split(',')
		num1, num2 = int(num1), int(num2)
		num3 = num1 + num2
		out_file.write(str(num1) + "," + str(num2) + "," + str(num3) + "\n")
		continue

Which outputs external file "file2.txt", although without headers that I removed using command "next(in_file)"

Output:
324,234,558
346,341,687
147,346,493
234,567,801
368,405,773
344,643,987
235,235,470
236,567,803
