AttributeError

[Ltc Hotspot]

The problem here is that these are home work assignment and to code an
else word assignment would be in contradiction to the academic
curriculum.

Specifically, I want to deploy a quick and simply dic solution:

Revised code:
c = [0 for i in range(24)]
filename = raw_input("Enter file name: ")
f = open(filename,'r')
for l in f:
    h = int(l.strip().split()[X].split(':')[Y])
    c[h] = c[h] + 1
f.close()
for i in range(24):
    print '{:02d} {}'.format(i, c[i])
---------------------------------------------------------------------------
NameError
Traceback (most recent call last)
C:\Users\vm\Desktop\apps\docs\Python\week_10\assignment_10_2_v_10.py in <module>
()
      5 f = open(filename,'r')
      6 for l in f:
----> 7     h = int(l.strip().split()[X].split(':')[Y])
      8     c[h] = c[h] + 1
      9 f.close()

NameError: name 'X' is not defined

In [74]: print X
---------------------------------------------------------------------------
Print X:
NameError
Traceback (most recent call last)
<ipython-input-74-7510f249b93c> in <module>()
----> 1 print X

NameError: name 'X' is not defined
