Question

Write a program that counts the distribution of the hour of the day for all the event logs in the messages file. You can pull the hour from the “Nov, Oct, etc. ” line by finding the time string and then splitting that string into parts using the colon character. Once you have accumulated the counts for each hour, print out the counts, one per line, sorted by hour as shown below.  

Sample Execution: python timeofday.py Enter a file name: all_messages

04 3

06 1

07 1

09 2

Please Python Programming

Answer 1

Answer Code:

filename = input("Enter a file name: ") # user input for file

data = {} # dictionary to store the data

fileObj = open(filename, 'r') # opening the file in read mode

for line in fileObj.readlines(): # for to read data line by line

time = line.split(" ")[2] # spliting the row by space anf storing the time stamp

hour = time.split(':')[0] # spliting the time stamp to get the hour value

if hour in data.keys(): # check if hour already in dictionay

data[hour] += 1 # if yes then increment the value by 1

else:

data[hour] = 1 # else assignment the value 1, as it is his first occurence in the file

fileObj.close() # closing the file

for key in sorted(data): # sorted function sort the dictionary by keys and return the list of sorted keys

print(str(key) + " " +str(data[key])) # printing the desired output
