[Tutor] how to join two text files ?

[Mateusz K]

Well...it looks like I do not know how to use it. Could You help me

Example file_1:
====================================================================
20 53 2.66196
21 53 2.67512
20 52 2.63444
21 52 2.94148
====================================================================

Example file_2:
====================================================================
20 53 1.75904
21 53 2.92742
20 52 2.79653
21 52 2.12499
====================================================================

and so on....

my script:
====================================================================
import glob
{some code here}
####here is loop which change folder_daty, zmienna and 
folder_serw:##########

     plik2=folder_daty+zmienna+"XYZ.txt"
     zbiorcze = folder_serw + zmienna + ".txt"
     if not os.path.isfile(zbiorcze):
         shutil.copy(plik2, zbiorcze)
     else:
         with open(zbiorcze, "wb") as w:
             writer = csv.writer(w)
             for f in glob.glob(plik2):
                 rows = open(f, "rb").readlines()
                 writer.writerows(rows)
====================================================================


and result looks like:
====================================================================
2,0, ,5,3, ,2,.,4,4,8,2,"
"
2,1, ,5,3, ,3,.,0,4,9,9,6,"
"
2,0, ,5,2, ,3,.,1,8,4,9,5,"
"
2,1, ,5,2, ,3,.,3,2,2,6,5,"
"
====================================================================
