Answer 1

#usr/bin/python 
input = "_20161002_1630_"

# removing _ from start and end
string = input[1:-1]

#seprating date and time
date, time = string.split("_")

# formatting date
formatted_date = date[:4] + "/" + date[4:6] + "/" + date[6:]

# adding zeros to make time into hrsminsseconds
time = (time + "00") if len(time) < 5 else time

#formatting time
formatted_time = time[:2] + ":" + time[2:4] + ":" + time[4:]

# rejoining output
output = formatted_date + " " + formatted_time
