You are given a text file that contains the timetable for buses that travel a college campus. The first line of the file contains the name for each stop on the bus system separated by colons. Each following line contains the times using a 24-hour clock at which each bus in the system will arrive at a bus stop, also separated by colons.The timetable will have the following format:

Edinburgh:Danderhall:Dalkeith:Edgehead:Pathhead:Blackshiels:Oxton:Carfraemill:Lauder:Earlston:Leaderfoot:Newtown St Boswells:St Boswells:Clintmains:Kelso

0850:0911:0918:0930:0933:0939:0953:0955:1001:1015:1025:1029:1032:1038:1055

Write a program in Python that reads this file and outputs a row for each bus stop, showing the times when a bus arrives at that stop

Expert Solution

CODE:

file = open('data.txt','r')
#reading the lines in the file
lines = [x.split('\n')[0] for x in file.readlines()]
busStops = {}
#storing all the busStop names as keys of a dictionary
for i in lines[0].split(':'):
#each key has a list of times a bus will arrive at that particular stop
busStops[i] = []
#for each key value or busStop
for k,j in enumerate(busStops.keys()):
for i in range(1,len(lines)):
#the kth time value on each line is the time to be stored in that key's list
busStops[j].append(lines[i].split(':')[k])
#printing all the details
for i in busStops.keys():
print('Stop Name: ',i,'\nTimings for buses at this stop are(in 24 hrs format):')
for j in busStops[i]:
print(j,end = ' ')
print('\n')

Given some data in a text file, the task is to scramble the text and output in a separate text file. So, we need to write a Python program that reads a text file, scrambles the words in the file and writes the output to a new text file. Rules to be followed: Words less than or equal to 3 characters need not be scrambled. Don’t scramble first and last char, so Scrambling can become Srbmnacilg or Srbmnailcg or Snmbracilg,...
