You are required to write a program to sort the (name, age, height) tuples by ascending order where name is string, age and height are numbers. The tuples are input by console. The sort criteria is: # 1: Sort based on name; # 2: Then sort based on age; # 3: Then sort by score. # The priority is that name > age > score. # If the following tuples are given as input to the program: # Tom,19,80 # John,20,90 # Jony,17,91 # Jony,17,93 # Json,21,85 # Then, the output of the program should be: # [('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85'), ('Tom', '19', '80')] # Hints: # In case of input data being supplied to the question, it should be assumed to be a console input. # We use itemgetter to enable multiple sort keys. from operator import itemgetter, attrgetter l = [] while True: s = input() if not s: break l.append(tuple(s.split(","))) print(sorted(l, key=itemgetter(0,1,2))) # 14. Write a program which accepts a sequence of comma separated 4 digit binary numbers as its input and then check whether they are divisible by 5 or not. The numbers that are divisible by 5 are to be printed in a comma separated sequence. # Example: # 0100,0011,1010,1001 # Then the output should be: # 1010 # Notes: Assume the data is input by console. # Hints: # In case of input data being supplied to the question, it should be assumed to be a console input. def check(x): # converts binary to integer & returns zero if divisible by 5 total,pw = 0,1 reversed(x) for i in x: total+=pw * (ord(i) - 48) # ord() function returns ASCII value pw*=2 return total % 5 data = input().split(",") # inputs taken here and splited in ',' position lst = [] for i in data: if check(i) == 0: # if zero found it means divisible by zero and added to the list lst.append(i) print(",".join(lst)) # 15. Write a program to compute the frequency of the words from the input. The output should output after sorting the key alphanumerically. # Suppose the following input is supplied to the program: # New to Python or choosing between Python 2 and Python 3? Read Python 2 or Python 3. # Then, the output should be: # 2:2 # 3.:1 # 3?:1 # New:1 # Python:5 # Read:1 # and:1 # between:1 # choosing:1 # or:2 # to:1 # Hints # In case of input data being supplied to the question, it should be assumed to be a console input. freq = {} # frequency of words in text line = input() for word in line.split(): freq[word] = freq.get(word,0)+1 words = freq.keys() words = sorted(words) for w in words: print("%s:%d" % (w,freq[w]))
