Ekşi Duyuru

Selamlar,

Elimde yuzlerce .dat dosyasi var ve benim bu dosyalardaki ilk 3 satiri silmem gerekiyor. Arta kalan python kirintilari ve google vasitasiyla su noktaya kadar geldim ama ilerlemiyor.
Ekran goruntusu: ibb.co

Yardimci olabilirseniz sevinirim. Tesekkurler!

title_main=input("please enter the main part of the data file title")
title_start=input("please enter what is the starting number of data")
title_finish=input("please enter what is the finishing number of data")
title_start=int(title_start)
title_finish=int(title_finish)

for title_name in range(title_start, title_finish):
title_start=str(title_start)
title_finish=str(title_finish)
title_name=title_main + title_start + ".dat"
a_file = open(title_name, "r")
thenumber=thenumber+1 #get list of lines

lines = a_file.readlines()
a_file.close()

del lines[1] #delete lines


new_file = open(title_name, "w+") #write to file without line

for line in lines:
new_file.write(line)

new_file.close()

title_start=int(title_start)
title_finish=int(title_finish)
thenumber=int(thenumber)
thenumber=title_start+1
else:
print("done")
