Python3 issue regarding index out of range - python-3.x

Question

I am having this problem. When i run this code, with the above file it gives me a index out of range error.
f = open(sys.argv[1], 'r')
file_contents = [x.split('\t')[2:5] for x in f.readlines()]
#Set the variables for average and total for cities
total = 0
city = set()
for line in file_contents:
print(line[0])
This is the content for the file
2012-01-01 09:00 San Jose Men's Clothing 214.05 Amex
2012-01-01 09:00 Fort Worth Women's Clothing 153.57 Visa

Answer 1

You need to close the file after reading from it, the recommended practice is to open it using the with statement which automatically closes it;
with open(sys.argv[1], 'r') as f:
file_contents = [x.split(' ')[2:5] for x in f.readlines()]
#Set the variables for average and total for cities
total = 0
city = set()
for line in file_contents:
print(line[0])
However the issue you are having is splitting the lines by \t, use a blank space and it should give you what you need.
OUTPUT
09:00
09:00
09:00
