NamedTuple Example in Python

import collections 

Movie = collections.namedtuple('Movie',['MovieID','Title','Genres'])  #NamedTuple Example

M = Movie('1','Toy Story (1995)',"Animation|Children's|Comedy") 

print(M[0])

print(M[1])

print(M.MovieID)

print(M.Title)

print(M.Genres)

1

Toy Story (1995)

1

Toy Story (1995)

Animation|Children's|Comedy

#NamedTuple Example : #1

import collections 

Movie = collections.namedtuple('Movie',['MovieID','Title','Genres']) 

def parseMovie(_row):

fields = _row.split("::")

movieid = (int) (fields[0])

title = fields[1]

genres = fields[2]

M = Movie(movieid,title,genres)

return M

print(parseMovie("1::Toy Story (1995)::Animation|Children's|Comedy"))

Answer:

Movie(MovieID=1, Title='Toy Story (1995)', Genres="Animation|Children's|Comedy")

#NamedTuple Example : #2

import collections 

from datetime import datetime

Rating = collections.namedtuple('Rating',['UserID','MovieID','Rating','Timestamp']) 

def parseRatingRecord(_row):

fields = _row.split("::")

userid = (int) (fields[0])

movieid = (int) (fields[1])

rating = (int) (fields[2])

_timestamp = datetime.fromtimestamp((int) (fields[3]))

_rating = Rating(userid,movieid,rating,_timestamp)

return _rating

print(parseRatingRecord("1::1193::5::978300760"))

Answer:

Rating(UserID=1, MovieID=1193, Rating=5, Timestamp=datetime.datetime(2001, 1, 1, 3, 42, 40))

#Example 3

import collections

User = collections.namedtuple("Users",["UserID","Gender","Age","Occupation","ZipCode"])

def parseUserRecord(_row):

fields = _row.split("::")

userid = (int)(fields[0])

gender= fields[1]

age = (int) (fields[2])

occupation = (int) (fields[3])

zipcode = (int) (fields[4])

_user = User(userid,gender,age,occupation,zipcode) 

return _user

print(parseUserRecord("3::M::25::15::55117"))
