HowTo Search in nested lists

[Florian Lindner]

Hello,
I've two nested lists which are representing a table or matrix.

A = [1, 2, 3]
B = [4, 5, 6]
C = [7, 8, 9]

t = [A, B, C]

print t[0][2] # Prints 3

Now I found to search for certain values in a certain column.
For example: column 1, search for 5, return 1, because 5 is found in the
first column of the second element of t

I hope I could explain what I want. Is there any way to do that except:

for i in len(t):
  if t[i][1] == "phrase":
    found = i
    break

Thx,
Florian
