Python Lists ,set,tuple and Dictionary

The following table contains some examples of lists:

Answer explanation

Empty List

A List of Integers

A list of mixed data types

A List of Strings

A nested list

A deeply nested listEmpty List

Select all the correct statements given below.

• All elements in a list should be of same data type.

•   Lists are immutable.

• Lists are ordered and can contain other lists as elements.

• Indexing can be used with lists to access individual items only if there are no nested lists.

Write a python program for list by using extend and append methods.

SAMPLE TEST CASE

hi

hello

Lists

['hi', 'hello', 'Python']

['hi', 'hello', 'Python', 'Code is Life']

['hi', 'hello', 'Python', 'Code is Life', 45, 67, 89]

list1 = ["hi", "hello", "Lists"]

Answer explanation

hi

hello

Lists

['hi', 'hello', 'Python']

['hi', 'hello', 'Python', 'Code is Life']

['hi', 'hello', 'Python', 'Code is Life', 45, 67, 89]

list1 = ["hi", "hello", "Lists"]

Write a program to determine if a given element is present in a list or not. Print the result as shown in the sample test cases.

Sample Input and Output 1:

data: Python,Java,Perl

element: Java

True

Answer explanation

data: Python,Java,Perl

element: Java

True

Write a program to get list elements using slicing as shown in the example.

Sample Input and Output:

a = [9, 8, 7, 6, 5, 4]

a[0:3] = [9, 8, 7]

a[:4] = [9, 8, 7, 6]

a[:] = [9, 8, 7, 6, 5, 4]

a[2:2] = []

a[0:6:2] = [9, 7, 5]

a[-3:] = [6, 5, 4]

a[:-3] = [9, 8, 7]

Answer explanation

a[0:3] = [9, 8, 7]

a[:4] = [9, 8, 7, 6]

a[:] = [9, 8, 7, 6, 5, 4]

a[2:2] = []

a[0:6:2] = [9, 7, 5]

a[-3:] = [6, 5, 4]

a[:-3] = [9, 8, 7]

plist = ['red', 'orange', 'blue', 'green', 'yellow', 'cyan']

elem = plist.pop()

print(elem)________________________

elem = plist.pop(-1)

print(elem)_____________________________

print(plist)____________________________

Write a program to find the difference between the maximum and the minimum elements of a list and print the result as shown in the example.

 

Sample Input and Output:data: 12,52,96,85

min: 12

max: 96

difference: 84

Answer explanation

min: 12

max: 96

difference: 84

A set is a ________ data type that contains an ___________ collection of items. A set is represented with ______.

set of squares of even numbers and cubes of odd numbers between the user-given range. Fill in the missing code.

Sample Input and Output:

     n1: 1

      n2: 11

·[1, 4, 16, 27, 36, 64, 100, 125, 343, 729]

Answer explanation

n1: 1

 n2: 11

[1, 4, 16, 27, 36, 64, 100, 125, 343, 729]

Write a program to convert the tuple into list

The result should be as follows:

Given Tuple: ('i', 'love', 'python')

After Converting Tuple into List: ['i', 'love', 'python']

List after changing element: ['i', 'practice', 'python']

After Converting List into Tuple: ('i', 'practice', 'python

Answer explanation

The result should be as follows:

Given Tuple: ('i', 'love', 'python')

After Converting Tuple into List: ['i', 'love', 'python']

List after changing element: ['i', 'practice', 'python']

After Converting List into Tuple: ('i', 'practice', 'python
