10.2 Write a program to read through the mbox-short.txt and figure out the distribution by hour of the day for each of the messages. You can pull the hour out from the 'From ' line by finding the time and then splitting the string a second time using a colon.

Please help me with the code, however I correct the code I'm getting the #error

Hey did you solve the issue? I am also facing the same problem

Yes I solved the problem.
Just leave space after 'm' in 'From '

`name = input("Enter file:")
if len(name) < 1:
name = "mbox-short.txt"
handle = open(name)

email = dict()
for line in handle:
if not line.startswith('From '): continue
time = line.split()
hour = time[5].split(':')[0]
email[hour] = email.get(hour,0) +1

lst = list()
for k,v in email.items():
lst.append([k,v])
lst = sorted(lst)

for k,v in lst:
print(k,v)
`

@ChernetAsmamaw i used the code you provided but still it says list index out of range.

@Le12vi A "list index out of range" error occurs when you try to access an index of a list that does not exist. Perhaps you made a mistake when naming your list variables, could you check that?

handle = open('mbox-short.txt')

hour = words[5][0:2] #pinpoints the time in the line and further splits to show only hour
count[hour] = count.get(hour, 0) + 1 #counts how many times that hour shows up

for k, v in count.items(): hours.append((k, v))
hours.sort() #sorts dictionary by key

My code can not do well, can anyone find some problems? thankyou!!!

Hi, here's mine

    name = "mbox-short.txt"
handle = open(name)

for line in handle:
    line_splited = line.split(" ")
    if line_splited[0] == "From":
        hour_list.append(line_splited[6][0:2])

for hour in sorted(hour_list):
    if hour_dictionary.get(hour, False) == False:
        hour_dictionary[hour] = 1
    else:
        hour_dictionary[hour] = hour_dictionary[hour] + 1

for key, value in hour_dictionary.items():
    print(key, value)

name = input("Enter file:")
if len(name) < 1:
    name = "mbox-short.txt"
handle = open(name,'r')

counts = dict()

for line in handle: 
    if line.startswith("From "):
        pos = line.find(":")
        time = (line[pos-2 : pos]) #finding hour
        counts[time] = counts.get(time,0) + 1 #creating dictionary

order = sorted(counts.items())
for key, value in order : print(key, value)

    

Hey guys this is my code on the Q it works nicely but if there is anything that I did wrong or I could have initially avoided pls let me know :)

fname = input("Enter File Name: ")
fhandle = open(fname)
lst = list()
count = dict()
finallist = list()
for line in fhandle:
if line.startswith("From") and not line.startswith("From:"):
line = line.split()
lst.append(line[5])

for hour in lst:
hour = hour.split(":")
finallist.append(hour[0])

for ftime in finallist:
count[ftime] = count.get(ftime, 0) + 1

for x, y in sorted(count.items()):
print(x, y)
