Q. Convert 2.5GB into bytes                                                                                      

(2.5 x 1024 x 1024 x 1024) Bytes

GB -> MB -> KB -> Byte

 

Q.     Write output of following                                                                                    

i.                    print(“kv\nnepa”)

kv

nepa

 

ii.                  x, x=12,15

y, y=x+10,x+20

print(x, y)

 

x = 15, y = 35

 

iii.                print(4/2)

2.0

 

Q.     write name of function to find datatype of a variable x.                                                

type()

Q.     write a program to input a number form user and find its square.                               

num = int(input(“Enter a Number”))

sqr = num*num

print(“Square of “, num, ” is “, sqr)

 

Q.     Q. Convert into python expression                                                                                 

    Q  -     A

            (B+P)⁸

 

Q – A/((B+P)**8)

 or

Q - A/math.pow((B+P),8)

 

Q.     Write a program to obtain x, y, z from user and calculate 4x² + 3y³ + 9z + 18  

import math

x = int(input(“Enter value of x”))

y = int(input(“Enter value of y”))

z = int(input(“Enter value of z”))

res = 4*(x**2) + 3*(y**3) + 9*z + 18*math.pi

print(res)

 

Q.      Given a list iterate it and display numbers which are divisible by 5 and if you find number greater than 150 stop the loop iteration                                                  

list1 = [12, 15, 32, 42, 55, 75, 122, 132, 150, 180, 200]

Expected output:

15

55

75

150

list1 = [12, 15, 32, 42, 55, 75, 122, 132, 150, 180, 200]

for i in list1:

    if(i>150):

        break

    if(i%5 == 0):

        print(i)

 

Q.     Q.  Write a program to Reverse the following list using for loop                                 

list1 = [10, 20, 30, 40, 50]

Expected output:

50

40

      30

20

10

list1 = [10, 20, 30, 40, 50]

for i in range(len(list1)-1, -1 , -1):

    print(list1[i])

 

Q.     Q. Write a program to Accept number from user and calculate the sum of all number between 1 and given number                                                                         

For example user given 10 so the output should be 55

 

num = int(input(“Enter a NUmber”))

sum = 0

for i in range(1,num+1):

    sum = sum + i

print(sum)

Dictionaries Manipulation Practice

Dictionaries Manipulation Practice

Question:
Write a program to print the worker’s informations (Name age, salary) in records format.
Answer:
Employees = {‘Rohan’ : {‘age’ : 20, ‘salary’ : 10000}, ‘Mohan’ : {‘age’ : 30, ‘salary’ : 15000}}
for key in Employees :
    print “Employee”, key + ‘:’
    print ‘Age :’ + str (Employees [key] [‘age’]
    print ‘Salary :’ + str (Employees [key] [‘salary’])

Question:
What is a key-value pair with reference to Python dictionary ?
Answer:
A dictionary is a mapping between a set of indices (which are called keys) and a set of values. Each key maps a value. The association of a key and a value is called a key-value pair.

Question:
What are the characteristics of Python Dictionaries ?
Answer:
The 3 main characteristics of a dictionary are :

1.    Dictionaries are Unordered : The dictionary elements (key-value pairs) are not in ordered form.

2.    Dictionary Keys are Case Sensitive : The same key name but with different case are treated as different keys in Python dictionaries.

3.    No duplicate key is allowed : When duplicate keys encountered during assignment, the last assignment wins.

4.    Keys must be immutable : We can use strings, numbers or tuples as dictionary keys but something like [‘key’] is not allowed.

Question:
Write a Python program to input ‘n’ names and phone numbers to store it in a dictionary and to input any name and to print the phone number of the particular name.
Answer:
phonebook = dict( )

n = int(input("Enter total number of friends"))

i = 1

while i<=n:

    a = input("Enter name")

    b = input("Enter phone number")

    phonebook[a] = b

    i = i + 1

print("Dictionary is:- ")

print(phonebook)

name = input("Enter name to search")

if name in phonebook.keys():

        print("Phone number =", phonebook[name])

else:

    print("Given name not exist")
