1. Extract title Write a function extract_title that takes one parameter, the filename of a GenBank formatted file, and returns

trapecia [35]

Answer:

def extract_title(file):

import re

a =''

with open(file,'r') as file:

for line in file:

a += line

m = re.search("^(TITLE)(.*?)(JOURNAL)", a, re.M + re.S)

print(m.groups()[1])

extract_title('new.txt')

Explanation:

The programming language used is python 3.

The function is first defined and the regular expression module is imported.

A variable is initialized to an empty string that will hold the content of the GenBank formatted file.

The file is opened and every line in the file is assigned to the string variable. The WITH statement allows files to be closed automatically.

Regular expression is used to capture all the files between TITLE and JOURNAL in a group.

The group is printed and the function is called.

I have attached a picture of the code in action.

1What kind of rules protect everyone’s rights when we use each other’s content

Tanya [424]

Answer:

1. Copyright.

2. Songs and books.

Explanation:

A copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

For example, when an individual downloads a song owned by any record company without paying a purchase fee, it is a violation of copyright law.

A copyright can be defined as an exclusive legal right granted to the owner of a creative work (intellectual property) to perform, print, record, and publish his or her work. Also, the owner is granted the sole right to authorize any other person to use the creative work.

Hence, copyright is a kind of rules that protect everyone’s rights when we use each other’s content.

An intellectual property can be defined as an intangible creation of the human mind, ideas, thoughts or intelligence. Some examples of an intellectual property are songs, books, poems, technology, design etc.

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is

nalin [4]

Answer:

Date Date::operator++( int )

{

Date temp = *this;

Increment();

return temp;

}

Explanation:

Of options 1 through 4, only option 4 correctly implement the post increment of the ++ operator.

Interpreting each line of option for and comparing it to other options

Line 1: Date Date::operator++( int )

This declares the data type and its ++ operator

This is same for all options

Line 2: The Date type needs to be declared

In option 4, it was declared correctly as Date temp = *this; using a pointer variable *this.

Here, option 2 is removed from the list of possible options.

Comparing other options

Line 3: The member increment option needs to be declared after the declaration of the date type variable.

This is correctly declared as Increment(); in option 4

Here, option 3 is removed from the list of possible options.

Comparing other options

Line 4: The value declared variable temp needs to be returned the way it was declared (without pointer indicator)

Hence, option 4 is best appropriate
