import csv
def Add_Book():
bid=""
bname=""
pub=""
f=open(“Book.csv”,"w” newline=")
bookwriter=csv.writer(f)
ans="y’
bookrec=[]
while ans=='y':
bid=input(“Enter book id :")
bname=input(“Enter book name :")
pub= input(“Enter publisher :")
rec=( bid,bname,pub)
bookrec.append(rec)
ans=input(“Continue(y/n)”)
bookwriter.writerows(bookrec)
f.close()

Write a function EOReplace() in Python, which accepts a list L of numbers. Thereafter, it increments all even numbers by 1 and decrements all odd numbers by 1.
Example:
If Sample Input data of the list is:
L = [10, 20, 30, 40, 35, 55]Output will be:
L = [11, 21, 31, 41, 34, 54]Write the output of the code given below:
def short_sub (1st, n):
for i in range (0, n):
if len (1st) > 4:
lst [i] = lst [i] + lst [i]
else:
lst [i] = lst [i]
subject = ['CS', 'HINDI', 'PHYSICS', 'CHEMISTRY', 'MATHS']
short_sub (subject, 5)
print (subject)Write the output of the code given below:
a = 30
def call (x):
global a
if a%2==0:
x+=a
else:
x−=a
return x
x=20
