Stopped twatting about and finished day 2.

I really wanted this to work without iteration, but I was getting nowhere.

#!/usr/bin/python
import timeit
from pandas import read_table
df = read_table('input_day2.txt', sep='-| |: ', header=None, engine='python')

# Part 1
starttime = timeit.default_timer()
my_check = 0 
for index, row in df.iterrows():
    my_check = my_check + (row[3].count(row[2]) >= row[0] and row[3].count(row[2]) <= row[1])
print("Part 1 - Number of valid passwords:", my_check)
print("Time taken: ", timeit.default_timer() - starttime)

# Part 2 
starttime = timeit.default_timer()
my_check = 0 
for index, row in df.iterrows():
    my_check = my_check + ((row[3][row[0]-1] == row[2]) is not (row[3][row[1]-1] == row[2]))
print("Part 2 - Number of valid passwords:", my_check)
print("Time taken: ", timeit.default_timer() - starttime)
