Error - list index out of range

[Einat]

Hi all,

I'm just starting my way into Python and I'm trying to use a while loop with lists but keep getting the list index out of range error.
(Please ignore any other foolish mistakes I might find later on J):

  DBReportsArray = [6000,5000,4000,3000,2000,1000,100]         
  curNum = 0 
  RepInDB = tssh.command ("ls -l /something | wc -l")[0] ##something to get a result by ssh
  RepInDB = [y.replace("\n","") for y in RepInDB] ##replaces a non-good format
  RepInDB = RepInDB[0]
  print RepInDB ##I got 351
  print self.DBReportsArray[curNum] 
  while self.DBReportsArray[curNum] <= RepInDB: 
     curNum+=1
  RepToChange = RepInDB-self.DBReportsArray[self.curNum]
  print RepToChange
 

Thanks in advance,
Einat

Einat,

Either RepInDb is an empty list, or the value of curNum is equal to or exceeds the length of the list self.DBReportsArray as in:

>>> [][0]
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
IndexError: list index out of range
>>> alist = [0,1,2,3,4,5]
>>> alist[0]
 0
>>> alist[5]
5
>>> alist[6]
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
IndexError: list index out of range
>>>

Appreciate your reply.

I tried verifying the content of RepInDb and curNum and both were in order.
Anyway I converted the "while" loop to a "for" loop and now it works:

DBReportsArray = [6000,5000,4000,3000,2000,1000,100]         
curNum = 0 
RepInDB = tssh.command ("ls -l /something | wc -l")[0] ##something to get a result by ssh
RepInDB = [y.replace("\n","") for y in RepInDB] ##replaces a non-good format
RepInDB = RepInDB[0]
print RepInDB
for num in range(len(self.DBReportsArray)):
    if self.DBReportsArray[num] <= RepInDB:
       break
    return num,RepInDB 
 

Thanks again,
E
