Question 6

Question 15What do you understand by undefined variable in Python ?

Accepted Answer

In Python, a variable is not created until some value is assigned to it. A variable is created when a value is assigned to it for the first time. If we try to use a variable before assigning a value to it then it will result in an undefined variable. For example:print(x)   #This statement will cause an error for undefined variable x
x = 20
print(x)The first line of the above code snippet will cause an undefined variable error as we are trying to use x before assigning a value to it.

Question 7

Question 18What is the error in following code : X, Y = 7 ?

Accepted Answer

The error in the above code is that we have mentioned two variables X, Y as Lvalues but only give a single numeric literal 7 as the Rvalue. We need to specify one more value like this to correct the error:X, Y = 7, 8

Question 8

Question 19Following variable definition is creating problem X = 0281, find reasons.

Accepted Answer

Python doesn't allow decimal numbers to have leading zeros. That is the reason why this line is creating problem.

Question 9

Question 20"Comments are useful and easy way to enhance readability and understandability of a program." Elaborate with examples.

Accepted Answer

Comments can be used to explain the purpose of the program, document the logic of a piece of code, describe the behaviour of a program, etc. This enhances the readability and understandability of a program. For example:# This program shows a program's components

# Definition of function SeeYou() follows
def SeeYou():
    print("Time to say Good Bye!!")

# Main program-code follows now
a = 15
b = a - 10
print (a + 3)
if b > 5:         # colon means it's a block
    print("Value of 'a' was more than 15 initially.")
else:
    print("Value of 'a' was 15 or less initially.")

SeeYou()          # calling above defined function SeeYou()

Question 10

Question 1From the following, find out which assignment statement will produce an error. State reason(s) too.(a) x = 55(b) y = 037(c) z = 0o98(d) 56thnumber = 3300(e) length = 450.17(f) !Taylor = 'Instant'(g) this variable = 87.E02(h) float = .17E - 03(i) FLOAT = 0.17E - 03

Accepted Answer

y = 037 (option b) will give an error as decimal integer literal cannot start with a 0.z = 0o98 (option c) will give an error as 0o98 is an octal integer literal due to the 0o prefix and 8 & 9 are invalid digits in an octal number.56thnumber = 3300 (option d) will give an error as 56thnumber is an invalid identifier because it starts with a digit.!Taylor = 'Instant' (option f) will give an error as !Taylor is an invalid identifier because it contains the special character !.this variable = 87.E02 (option g) will give an error due to the space present between this and variable. Identifiers cannot contain any space.float = .17E - 03 (option h) will give an error due to the spaces present in exponent part (E - 03). A very important point to note here is that float is NOT a KEYWORD in Python. The statement float = .17E-03 will execute successfully without any errors in Python.FLOAT = 0.17E - 03 (option i) will give an error due to the spaces present in exponent part (E - 03).

Question 11

Question 3Find out the error(s) in following code fragments:(i)temperature = 90
print temperature

Accepted Answer

The call to print function is missing parenthesis. The correct way to call print function is this:print(temperature)(ii)a = 30
b=a+b
print (a And b)There are two errors in this code fragment:In the statement b=a+b variable b is undefined.In the statement print (a And b), And should be written as and.(iii)a, b, c = 2, 8, 9
print (a, b, c)
c, b, a = a, b, c
print (a ; b ; c)In the statement print (a ; b ; c) use of semicolon will give error. In place of semicolon, we must use comma like this print (a, b, c)(iv)X = 24
4 = XThe statement 4 = X is incorrect as 4 cannot be a Lvalue. It is a Rvalue.(v)print("X ="X)There are two errors in this code fragment:Variable X is undefined"X =" and X should be separated by a comma like this print("X =", X)(vi)else = 21 - 5else is a keyword in Python so it can't be used as a variable name.

Question 12

Question 5What is the problem with the following code fragments ?(i)a = 3
    print(a)
b = 4
    print(b)
s = a + b
    print(s)

Accepted Answer

The problem with the above code is inconsistent indentation. The statements print(a), print(b), print(s) are indented but they are not inside a suite. In Python, we cannot indent a statement unless it is inside a suite and we can indent only as much is required.(ii)name = "Prejith"
age = 26
print ("Your name & age are ", name + age)In the print statement we are trying to add name which is a string to age which is an integer. This is an invalid operation in Python.(iii)a = 3
s = a + 10
a = "New"
q = a / 10The statement a = "New" converts a to string type from numeric type due to dynamic typing. The statement q = a / 10 is trying to divide a string with a number which is an invalid operation in Python.

Question 13

Question 8Find the errors in following code fragment(a)y = x + 5
print (x, Y)

Accepted Answer

There are two errors in this code fragment:x is undefined in the statement y = x + 5Y is undefined in the statement print (x, Y). As Python is case-sensitive hence y and Y will be treated as two different variables.(b)print (x = y = 5)Python doesn't allow assignment of variables while they are getting printed.(c)a = input("value")
b = a/2
print (a, b)The input( ) function always returns a value of String type so variable a is a string. This statement b = a/2 is trying to divide a string with an integer which is invalid operation in Python.

Question 14

Question 10Consider the following code :name = input ("What is your name?") print ('Hi', name, ',') print ("How are you doing?")was intended to print output asHi , How are you doing ? But it is printing the output as :Hi , How are you doing? What could be the problem ? Can you suggest the solution for the same ?

Accepted Answer

The print() function appends a newline character at the end of the line unless we give our own end argument. Due to this behaviour of print() function, the statement print ('Hi', name, ',1) is printing a newline at the end. Hence "How are you doing?" is getting printed on the next line.To fix this we can add the end argument to the first print() function like this:print ('Hi', name, ',1, end = '')

Question 15

Question 11Find the errors in following code fragment :c = input( "Enter your class" )
print ("Last year you were in class") c - 1

Accepted Answer

There are two errors in this code fragment:c - 1 is outside the parenthesis of print function. It should be specified as one of the arguments of print function.c is a string as input function returns a string. With c - 1, we are trying to subtract a integer from a string which is an invalid operation in Python.The corrected program is like this:c = int(input( "Enter your class" )) 
print ("Last year you were in class", c - 1)

Question 16

Question 12What will be returned by Python as result of following statements?(a) >>> type(0)

Accepted Answer

(b) >>> type(int(0))(c) >>>.type(int('0')SyntaxError: invalid syntax(d) >>> type('0')(e) >>> type(1.0)(f) >>> type(int(1.0))(g) >>>type(float(0))(h) >>> type(float(1.0))(i) >>> type( 3/2)

Question 17

Question 16The id( ) can be used to get the memory address of a variable. Consider the adjacent code and tell if the id( ) functions will return the same value or not(as the value to be printed via print() ) ? Why ?[There are four print() function statements that are printing id of variable num in the code shown on the right.num = 13
print( id(num) )
num = num + 3
print( id(num) )
num = num - 3
print( id(num) )
num = "Hello"
print( id(num) )

Accepted Answer

num = 13
print( id(num) ) # print 1
num = num + 3
print( id(num) ) # print 2 
num = num - 3
print( id(num) ) # print 3
num = "Hello"
print( id(num) ) # print 4For the print statements commented as print 1 and print 3 above, the id() function will return the same value. For print 2 and print 4, the value returned by id() function will be different.The reason is that for both print 1 and print 3 statements the value of num is the same which is 13. So id(num) gives the address of the memory location which contains 13 in the front-loaded dataspace.

Question 18

Question 17Consider below given two sets of codes, which are nearly identical, along with their execution in Python shell. Notice that first code-fragment after taking input gives error, while second code-fragment does not produce error. Can you tell why ?(a)>>> print(num = float(input("value1:")) )  
value1:67

TypeError: 'num' is an invalid keyword argument for this function
(b)>>> print(float(input("valuel:")) )
value1:67

67.0

Accepted Answer

In part a, the value entered by the user is converted to a float type and passed to the print function by assigning it to a variable named num. It means that we are passing an argument named num to the print function. But print function doesn't accept any argument named num. Hence, we get this error telling us that num is an invalid argument for print function.In part b, we are converting the value entered by the user to a float type and directly passing it to the print function. Hence, it works correctly and the value gets printed.

Question 19

Question 2Write a program to read today's date (only del part) from user. Then display how many days are left in the current month.Solutionday = int(input("Enter day part of today's date: "))
totalDays = int(input("Enter total number of days in this month: "))
daysLeft = totalDays - day
print(daysLeft, "days are left in current month")OutputEnter day part of today's date: 16
Enter total number of days in this month: 31
15 days are left in current month

Accepted Answer

day=int(input("Enter day part of today's date: "))totalDays=int(input("Enter total number of days in this month: "))daysLeft=totalDays-dayprint(daysLeft,"days are left in current month")OutputEnter day part of today's date: 16Enter total number of days in this month: 3115 days are left in current month

Question 20

Question 4Modify above program so as to print output as 5@10@9.Solutiona = 5
print(a, end='@')
a = a * 2
print(a, end='@')
a = a - 1
