Q1. In front of the Python prompt In [ ]: in IPython console, type the following statements one by one.

(a) IMPORTANT: It would be more fruitful if students first evaluate the expressions on paper before typing in Python Shell as it will strengthen their learning of concepts.

(b) Do write the reason behind the result returned by Python.

Q1. In Spyder IDE, click --> File New File... and type the following code into it:

#This is another program with different components

#Function First5Multiples() follows

def First5Multiples():

    print ("6 * 1 =", (6*1))

    print ("6 * 2 =", (6*2))

    print ("6 * 3 =", (6*3))

    print ("6 * 4 =", (6*4))

    print ("6 * 5 =", (6*5))

# main code follows

print ("Hello")

b = 3

print ("Function First5Multiples() will print ", b + 2, "multiples of 6.")

First5Multiples() #function First Multiples() being called

if b + 2 > 5:

    print ( "The function printed ", b + 2, " multiples of 6.")

    print ("Python is amazing!")

    print ("I have started enjoying myself.")

Now save your code by pressing Ctrl + S or using File --> Save command.

Being in same window, run your code by pressing F5 key.

Now in the following boxes fill in the appropriate components of a program from the above code.

(a) Name the components in the above code

Name what all components do you see in above code, e.g. expression, statement etc.

(b) Number of Comments in the given code

(c) Number of full-line comments

(d) Number of inline comments

(e) The full-line comments

Write full-line comments from the above code:

(f) Inline comments

Write inline comments from the above code:

(e) Number of Expressions in above code

(h) Expressions Write expressions (in above code) below:

(i) Number of Statements in above code

(j) Statements Write Statements (in above code) below:

(k) Number of blocks/code-blocks in above code

(l) Blocks in above code Write below (the code blocks): (Do not write complete code, just the first line that requires block and the count of code lines in it.)

(m) Number of functions in above code

(n) Give function name and how many statements a part of Write below:

P.I.P :- 2.3

Practice #1

Click File --> New File... and type the following code into it:

myNumber = 10

print (myNumber + 1) # output statement 1

print (myNumber) # output statement 2

print (type (myNumber)) # type statement 1

myNumber = 5 + 2

print (myNumber, end = ()) # output statement 3

print (type (myNumber)) # type statement 2

myNumber = "Seven"

print (myNumber) # output statement 4

print (type(myNumber) # type statement 3

Now save your code and run it by pressing F5 key.

Now in the following table fill details as asked as per your observations based on above code:

 

 
	 
(a)
 
	 
Output generated by four marked output statements in above code.
 
	 
1.2.3.4.
 
 
 
	 
(b)
 
	 
Output generated by three marked type statements in above code
 
	 
1.2.3.
 
 
 
	 
(c)
 
	 
Why is the output of output statement 1 different from output statement 2 when we have added 1 to variable Number?
 
	 
 
 
 
	 
(d)
 
	 
Why is the output of type statement 2 different from type statement 3 when we are displaying output of same variable myNumber?
 
	 
 
 
 
	 
(e)
 
	 
Assign values 2, 4, 8 to variables a, b and c in single statement.
 
	 
 
 
 
	 
(f)
 
	 
Swap the values of a, b, c through SINGLE STATEMENT so as they now hold values of c, a, and b respectively.
 
	 
 
 
 
	 
(g)
 
	 
In a new program there is just one statement given belowprint (value)But it is giving problem upon running the program. Could you tell, why?
 
	 
 
 

Practice #2

Following code intends to obtain a number in variable x and then print its 5 multiples i.e., x, 2x, 3x, 4x, and 5x. Fill in the missing functionality and run your code.

# to obtain a number and print its 5 multiples

x = ___ (input ('_____'))

multiple1 = ____

multiple2 = ____

multiple3 = x* 3

multiple4 = ____

multiple5 = ____

print ('x =', ____)

print (________)

Alternative code

# to obtain a number and print its 5 multiples

x = ___ (input (' _____'))

print ('x =', ______)

print (x, ___, ___, ___, ___,)

Output produced by above code (First Alternative)

Output produced by above code (Second Alternative).
