Define a function typeHistogram that takes an iterator ""it"" (representing a sequence of values of different types) and builds
Alexeev081 [22]

Answer:

def typeHistogram(it,n):

   d = dict()

   for i in it:

       n -=1

       if n>=0:

           if str(type(i).__name__) not in d.keys():

               d.setdefault(type(i).__name__,1)

           else:

               d[str(type(i).__name__)] += 1

       else:

           break

   return list(d.items())

it = iter([1,2,'a','b','c',4,5])

print(typeHistogram(it,7))

Explanation:

  • Create a typeHistogram function that has 2 parameters namely "it" and "n" where "it" is an iterator used to represent a sequence of values of different types while "n" is the total number of elements in the sequence.
  • Initialize an empty dictionary and loop through the iterator "it".
  • Check if n is greater than 0 and current string is not present in the dictionary, then set default type as 1 otherwise increment by 1.
  • At the end return the list of items.
  • Finally initialize the iterator and display the histogram by calling the typeHistogram.

Why would you convert your birth year to binary numbers?
I am Lyosha [343]

Answer:

Write out your birthday in the following format: M/DD/YY. For example, if your birthday is on June 11, 2013, it would be written as 6/11/13.

2. Convert the birthday date to binary format. Using our same example from above, 6/11/13 translated into binary code would be: 110/1011/1101.

3. Select one color of bead to represent “0”, a second color to represent “1” and then the third color to represent a space (/) between the numbers.

4. Layout the beads to represent your birthdate in binary code. Don’t forget the third color for the spaces in between the numbers!

5. Once laid out, string all the beads on to the string or pipe cleaner.

6. Tie a knot around the ends and enjoy your one-of-a kind masterpiece as a piece of jewelry or a bag tag….the options are endless!
