Answer 2

Given:

A binary file with Emplyee.dat having structure (empno, ename, salary)

To Find:

In Python, that would read the file Emplyee.dat and display the details and count the number of employees whose name begin with A and S

Solution:

For reading the file,

import pickle

def addrec():

      fobj=open("Emplyee.dat","wb")

      eid=input("EnterE.Id")

      ename=input("Enter Name")

      designation=input("Enter designation")

      salary=int(input("Enter salary")

      I=[eId,ename,designation,salary]

      pickel.dump(I,f1)

      f1.close()

To Count the number of members with A and S as staring letters

Add,

test_list = [ 'Sanu' , 'Akash' , 'Nikil' , 'Manjeet' ]

check = 'A' , 'S'

print("The original test: " + str(test_list))

res = [idx for idx in test_list if idx[0].lower() == check.lower()]

print("The list of match first letter: " + str(res))
