Python data structures: Assignment 10.2

Coursera: Python data structures
Assignment 10.2
Week 6

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.
From stephen.marquard@uct.ac.za Sat Jan  5 09:14:16 2008
Once you have accumulated the counts for each hour, print out the counts, sorted by hour as shown below.

 Solution:

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

 for line in handle :
line = line.rstrip()
if line == "": continue
words = line.split()
if words[0] != "From" : continue
time = words[5].split(":")
counts[time[0]] = counts.get(time[0], 0) + 1

 list = list()

 for key,value in counts.items() :
list.append((key,value))
list.sort()

 for hour,count in list :

print(hour, count)

Python data structure: Assignment 8.4

Coursera : Python data structures Assignment 8.4 Week 4 8.4  Open the file  romeo.txt  and read it line by line. For each line, split the line into a list of words using the  split()  method. The program should build a list of words. For each word on each line check to see if the word is already in the list and if not append it to the list. When the program completes, sort and print the resulting words in alphabetical order. You can download the sample data at  http://www.py4e.com/code3 Solution: fname = input("Enter file name: ") fh = open(fname) lst = list() for line in fh:     for i in line.rstrip().split(' '):         lst.append(i) lst = list(set(lst)) lst.sort() print(lst) Coursera official website: https://www.coursera.org/learn/python-data/home/welcome

Programming for everybody (Python) Assignment 5.2

Coursera: Programming for everybody with Python  Assignment 5.2 Week 7 Question:- 5.2  Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number. Enter 7, 2, bob, 10, and 4 and match the output below. Solution:- largest = None smallest = None while True:  try:   num = input("Enter a number: ")   if num == "done":    break   #print (num)   num = int(num)   if largest is None or largest < num:    largest = num   elif smallest is None or smallest > num:    smallest = num  except ValueError:   print("Invalid input") print ("Maximum is", largest) print ("Minimum is", smallest) Official website for Coursera: https://...
