Function Practice Questions

  1. Predict the output of the following code: 
    
def Changer(P, Q=10):
    P=P/Q
    Q=P%Q
    return P

A=200
B=20
A=Changer(A, B)
print(A, B, sep='$')
B=Changer(B)
print(A, B, sep='$', end='###')

    2. 10.0$20
10.0$2.0###
  2. Rao has written a code to input a number and check whether it is prime or not. His code is having errors. Rewrite the correct code and underline the corrections made. 
    
def prime():
    n=int(input("Enter number to check :: ")
    for i in range (2, n//2):
        if n%i=0:
            print("Number is not prime \n")
        break
        else:
            print("Number is prime \n')

    3. def prime():
    n=int(input("Enter number to check :: "))
    for i in range (2, n//2):
        if n%i==0:
            print("Number is not prime \n")
            break
        else:
            print("Number is prime \n")
  3. Predict the output of the Python code given below: 
    
def Diff(N1,N2):
    if N1>N2:
        return N1-N2
    else:
        return N2-N1
    
NUM= [10,23,14,54,32]
for CNT in range (4,0,-1):
    A=NUM[CNT]
    B=NUM[CNT-1]
    print(Diff(A,B),'#', end=' ')
    4. 22 # 40 # 9 # 13 #
  4. Write the output of the code given below: 
    
p=5
def sum(q,r=2):
    global p
    p=r+q**2
    print(p, end= '#')

a=10
b=5
sum(a,b)
sum(r=5,q=1)
    5. 105#6#
  5. Consider the code given below : 

    b=100
def test(a):
      ______________  #missing statement
      b=b+a
      print(a, b)
test(10)
print(b)

    Which of the following statements should be given in the blank for #Missing Statement, if the output produced is 110?

    a. global a
b. global b=100
c. global b
d. global a=100
    6. (c) global b
  6. Rewrite the following code in Python after removing all syntax error(s). Underline each correction done in the code. 
    
Value=30
for VAL in range(0,Value)
    If val%4==0:
        print (VAL*4)
    Elseif val%5==0:
        print (VAL+3)
    else
        print(VAL+10)

    7. Value=30
for VAL in range(0,Value):
    if VAL%4==0:
        print (VAL*4)
    elif VAL%5==0:
        print (VAL+3)
    else:
        print(VAL+10)
  7. Find and write the output of the following Python code: 
    
def Display(str):
    m=""
    for i in range(0,len(str)):
        if(str[i].isupper()):
            m=m+str[i].lower()
        elif str[i].islower():
            m=m+str[i].upper()
        else:
            if i%2==0:
                m=m+str[i-1]
            else:
                m=m+"#"
    print(m)
