Python Tuple Assignment

Python Tuple Assignment-68
By carefully constructing the list of tuples to have the value as the first element of each tuple, we can sort the list of tuples and get our dictionary contents sorted by value.Coming back to our running example of the text from import string fhand = open('romeo-full.txt') counts = dict() for line in fhand: line = line.translate(str.maketrans('', '', string.punctuation)) line = line.lower() words = line.split() for word in words: if word not in counts: counts[word] = 1 else: counts[word] = 1 # Sort the dictionary by value lst = list() for key, val in list(counts.items()): lst.append((val, key)) lst.sort(reverse=True) for key, val in lst[:10]: print(key, val) # Code: and then sort the list in reverse order.You can pull the hour from the "From" line by finding the time string and then splitting that string into parts using the colon character.

But there are a few cases where you might prefer tuples: ; in this chapter we are starting to see compound data structures, like lists of tuples, and dictionaries that contain tuples as keys and lists as values.

Compound data structures are useful, but they are prone to what I call ; that is, errors caused when a data structure has the wrong type, size, or composition, or perhaps you write some code and forget the shape of your data and introduce an error.

We would encounter a composite key if we wanted to create a telephone directory that maps from last-name, first-name pairs to telephone numbers.

Assuming that we have defined the variables , then prints the name and corresponding telephone number.

This allows you to assign more than one variable at a time when the left side is a sequence.

In this example we have a two-element list (which is a sequence) and assign the first and second elements of the sequence to the variables Both sides of this statement are tuples, but the left side is a tuple of variables; the right side is a tuple of expressions.

Then sort the list in reverse order and print out the person who has the most commits.

Exercise 2: This program counts the distribution of the hour of the day for each of the messages.

Your program should not count spaces, digits, punctuation, or anything other than the letters a-z.

Find text samples from several different languages and see how letter frequency varies between languages.
