lists and tuples in python code example

Example 1: python list of tuples

#List of Tuples
list_tuples =  [('Nagendra',18),('Nitesh',28),('Sathya',29)]

#To print the list of tuples using for loop you can print by unpacking them
for name,age in list_tuples:
  print(name,age)

#To print with enumerate--->enumerate is nothing but gives the index of the array.
for index,(name,age) in list_tuples:
  #print using fstring
  print(f'My name is {name} and age is {age} and index is {index}')
  #print using .format
  print('My name is {n} and age is {a} and index is {i}'.format(n=name,a=age,i=index))

Example 2: 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
