Thank you for the time you´ll spend reading it.
 I have this kind of data (I´ll show only just a few lines bacuse it is almos 3000 lines)

evento\_T\_A.ascii

I did some programing (not the pythonic way) to ignore 2015-04-15T all this words and just trying to keep 

07:00:52.260000 15842 
07:00:52.270000 10292
...
07:00:52.390000 13574

here it is my code

```
ff=open('evento_T_A.ascii','r')
tiem=[]
for line in ff:
     line=line.strip()
     columns=line.split()
     Tiempo=columns[0]
     Amplitud=columns[1]
     Tiemp=str(Tiempo)
     if "T" in Tiemp:
          tiem=Tiemp[11:]
          print (repr(tiem))
     else:
          print "None"
ff.close()
outo=open('XY.txt','w')
for line in tiem:
    outo.writelines(repr(tiem))
outo.close()

```

but when I open the XY.txt I just get the last value not all the raw of data.
when I did the step `print (repr(tiem))` I could see all the data but when I did `outo.writelines(repr(tiem))` it just saved one line.

my first doubt:
- How can I merge Tiempo and Amplitud to look like this: 

```
07:00:52.260000  15842 
07:00:52.280000  10845
07:00:52.360000  11761
...
07:00:52.390000  13574

```

* how can write all the data in just one txt?

Thank you a lot for the time you spent reading it-
