Convert text file date into specific format

[jacklee26]

Thanks. I solve it
This is my code. Is there any comment with my code, or any suggestion.

import datetime as dt
from datetime import datetime
with open('holiday.txt') as f, open('new.txt', 'w') as f_out:
    for line in f:
        line = line.strip()
	#line =line.replace('/', '')
	#f_out.write('{}\n'.format(line))
	#f_out.write(datetime.strftime(datetime.strptime(line, '%Y/%m/%d'), '%Y%m%d'))
	line.rstrip().split('  ')
	line_1 = line.split()[0]
	line_2 = line.split()[1]
	newline =(datetime.strftime(datetime.strptime(line_1, '%Y/%m/%d'), '%Y%m%d'))
	#result = line_1 +" " +line_2
	#f_out.write(result)
	f_out.write(line_1 +" " +line_2+ '\n')
