List and tuple code example

Example 1: list of tuples python

import string
fhand = open('romeo-full.txt')
counts = dict()
for line in fhand:
    line = line.translate(None, 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 counts.items():
    lst.append( (val, key) )

lst.sort(reverse=True)

for key, val in lst[:10] :
    print key, val

Example 2: python tuple and list time compare

import timeit
print(timeit.timeit('x=(1,2,3,4,5,6,7,8,9)', number=100000))

print(timeit.timeit('x=[1,2,3,4,5,6,7,8,9]', number=100000))
