Q.Write the corresponding Python assignment statements:

Here are the corresponding Python assignment statements for each scenario:

(a) Assign 10 to variable length and 20 to variable breadth.

length = 10
breadth = 20

These statements use the assignment operator (=) to store integer values in the respective variables.

(b) Assign the average of values of variables length and breadth to a variable sum.

sum = (length + breadth) / 2

This statement first calculates the sum of length and breadth, then divides by 2 to find the average. The result is then assigned to the variable sum.

(c) Assign a list containing strings 'Paper', 'Gel Pen', and 'Eraser' to a variable stationery.

stationery = ['Paper', 'Gel Pen', 'Eraser']

This statement creates a list literal enclosed in square brackets [], with each string element separated by a comma, and assigns it to the stationery variable.

(d) Assign the strings 'Mohandas', 'Karamchand', and 'Gandhi' to variables first, middle and last.

first = 'Mohandas'
middle = 'Karamchand'
last = 'Gandhi'

Each string literal, enclosed in single quotes, is assigned to its corresponding variable using the assignment operator.

(e) Assign the concatenated value of string variables first, middle, last to variable fullname. Make sure to incorporate blank spaces appropriately between different parts of names.

fullname = first + ' ' + middle + ' ' + last

This statement uses the string concatenation operator (+) to join the values of first, middle, and last. Blank spaces are included as separate string literals (' ') between the name parts to ensure proper spacing in the fullname variable.

In Python, an assignment statement is used to bind a value to a variable name. The basic syntax is variable_name = value. The value can be a literal (like a number or a string), a result of an expression (like an arithmetic calculation), or a data structure (like a list).

Let's break down each part of the question.

a) Assign 10 to variable length and 20 to variable breadth.

This involves simple direct assignment of integer literals to two distinct variables.

length = 10
breadth = 20

• length = 10: The integer value 10 is assigned to the variable named length.
• breadth = 20: The integer value 20 is assigned to the variable named breadth.

b) Assign the average of values of variables length and breadth to a variable sum.

First, we need to calculate the sum of length and breadth, then divide by 2 to find the average. The result of this expression is then assigned to the variable sum. Note that the question asks to assign the average to a variable named sum, which might be slightly confusing as sum usually implies the total. However, we must follow the variable name specified.

# Assuming 'length' and 'breadth' are already defined from part (a)
average_value = (length + breadth) / 2
sum = average_value # Assigning the calculated average to 'sum' as per the question

• (length + breadth): This calculates the sum of the values currently stored in length and breadth.
• / 2: This divides the sum by 2 to compute the average. Python's / operator performs float division, which is appropriate for calculating averages.
• sum = average_value: The calculated average is assigned to the variable sum.

c) Assign a list containing strings 'Paper', 'Gel Pen', and 'Eraser' to a variable stationery.

A list in Python is an ordered, mutable collection of items. It is defined by enclosing comma-separated items within square brackets []. Each item in this case is a string literal.

stationery = ['Paper', 'Gel Pen', 'Eraser']

• ['Paper', 'Gel Pen', 'Eraser']: This creates a list containing three string elements.
• stationery = ...: This list is then assigned to the variable stationery.

d) Assign the strings 'Mohandas', 'Karamchand', and 'Gandhi' to variables first, middle and last.

Python allows for multiple assignments in a single line, which is very convenient for assigning several values to several variables simultaneously. The number of variables on the left side must match the number of values on the right side.

first, middle, last = 'Mohandas', 'Karamchand', 'Gandhi'

• 'Mohandas', 'Karamchand', 'Gandhi': These are three string literals.
• first, middle, last = ...: The first string is assigned to first, the second to middle, and the third to last.

e) Assign the concatenated value of string variables first, middle, last to variable fullname. Make sure to incorporate blank spaces appropriately between different parts of names.

String concatenation in Python can be done using the + operator. To include spaces between the names, we concatenate the variables with string literals containing a single space ' '.

# Assuming 'first', 'middle', and 'last' are already defined from part (d)
fullname = first + ' ' + middle + ' ' + last

• first + ' ' + middle + ' ' + last: This expression concatenates the string in first, a space, the string in middle, another space, and finally the string in last.
• fullname = ...: The resulting concatenated string is assigned to the variable fullname.

fullname_fstring = f"{first} {middle} {last}"

# Part (a)
length = 10
breadth = 20

# Part (b)
average_value = (length + breadth) / 2
sum = average_value

# Part (c)
stationery = ['Paper', 'Gel Pen', 'Eraser']

# Part (d)
first, middle, last = 'Mohandas', 'Karamchand', 'Gandhi'

# Part (e)
fullname = first + ' ' + middle + ' ' + last
