    Observe the following code carefully and rewrite if after removing all syntax and logical errors :
    Underline all the corrections made. [2 MARKS] [2024] 

    def EvenOdd() 
    for i in range(5) :

  4. Write a user defined function in Python named Puzzle(W, N) which takes the argument W as an English word and N as an integer and returns the string where every Nth alphabet of the word W is replaced with an underscore ("_"). For Example : if W contains the word "TELEVISION" and N is 3, then the function should return the string "TE_EV_SI_N". Likewise for the word "TELEVISION" if N is 4, then the function should return "TEL_VIS_ON". [2 MARKS] [2024]

  5. Write a user defined function in Python named showGrades(S) which takes the dictionary S as an argument. The dictionary, S contains Name : [Eng, Math, Science] as key : value pairs. The function displays the corresponding grade obtained by the students according to the following grading rules : [2 MARKS] [2024]

    Average of Eng, Math, Science Grade
    >=90 A
    <90 but >=60 B
    <60 C


    For example :
    Consider the following dictionary
    S={"AMIT" : [92,86,64], "NAGMA" : [65,42,43], "DAVID" : [92,90,88]}

    The output should be :
    AMIT - B
    NAGMA - C
    DAVID - A
    def showGrades(S):
    for i,j in S.items():
        avg=(j[0]+j[1]+j[2])/3

            print(i,"- A")
        elif avg>=60 and avg<90:
            print(i,"- B")
        elif avg<60:
            print(i,"- C")


D={"Amit":[92,86,64],"Nagma":[65,42,43],"David":[92,90,88]}
showGrades(D)
  6. Predict the output of the following code : [2 MARKS] [2024]

    def callon(b=20, a=10):
    b=b+a
    a=b-a
    print(b,"#",a)
    return b
x=100
y=200
x=callon(x,y)
print(x,"@",y)
y=callon(y)
print(x,"@",y)

    300 # 100
300 @ 200
210 # 200
300 @ 210

  11. 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. [3 MARKS] [2023]

    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]
    def EOReplace(L):
      for i in range(len(L)):
            if L[i]%2==0:
                  L[i]=L[i]+1
            else:
                  L[i]=L[i]-1
print(L)

or

def EOReplace():
      L=[]
      ch = 'y'
      while ch == 'y' or ch == 'Y':
            x = int(input('give item'))
            L.append(x)
            ch= input('do you want to enter more y/n ')
      for i in range(len(L)):
            if L[i]%2==0:
                  L[i]=L[i]+1
            else:
                  L[i]=L[i]-1
print(L)
