Question

Write the corresponding Python assignment statements:
a) Assign 10 to variable length and 20 to variable breadth.
b) Assign the average of values of variables length and breadth to a variable sum.
c) Assign a list containing strings ‘Paper’, ‘Gel Pen’, and ‘Eraser’ to a variable stationery.
d) Assign the strings ‘Mohandas’, ‘Karamchand’, and ‘Gandhi’ to variables first, middle and last.
e) Assign the concatenated value of string variables first, middle and last to variable fullname. Make sure to incorporate blank spaces appropriately between different parts of names.

Accepted Answer

> [!TLDR]
> Five direct assignment statements — including a parallel (tuple) assignment for the three name parts and string concatenation with explicit spaces for the full name.

**The idea.** Assignment binds a name to a value with `=`; Python also supports **parallel assignment** (`a, b = 1, 2`) and builds strings with the concatenation operator `+`.

```python
# a) Assign 10 to length and 20 to breadth
length = 10
breadth = 20
# (equivalently: length, breadth = 10, 20)

# b) Average of length and breadth into sum
sum = (length + breadth) / 2       # (10 + 20) / 2 = 15.0

# c) List of strings into stationery
stationery = ['Paper', 'Gel Pen', 'Eraser']

# d) Three strings into first, middle, last (parallel assignment)
first, middle, last = 'Mohandas', 'Karamchand', 'Gandhi'

# e) Concatenated full name with single spaces between the parts
fullname = first + ' ' + middle + ' ' + last
```

Verification of (e):

```python
>>> fullname
'Mohandas Karamchand Gandhi'
```

**Key points**
- (b) needs parentheses: `(length + breadth) / 2`. Without them, operator precedence would compute `length + (breadth / 2)` = 20.0 — the wrong average. Division `/` always yields a float, so `sum` is `15.0`.
- (d) parallel assignment unpacks the right-hand tuple left to right — one tidy line instead of three.
- (e) the `' '` literals supply the blank spaces the question asks for; `+` on strings concatenates.

> [!WARNING]
> Naming a variable `sum` (as the question directs) shadows the built-in function `sum()` for the rest of the program — fine for this exercise, but avoid it in real code.

> [!ANSWER]
> a) `length = 10` ; `breadth = 20`  b) `sum = (length + breadth) / 2`  c) `stationery = ['Paper', 'Gel Pen', 'Eraser']`  d) `first, middle, last = 'Mohandas', 'Karamchand', 'Gandhi'`  e) `fullname = first + ' ' + middle + ' ' + last` → 'Mohandas Karamchand Gandhi'.

Input type	What it reads	Example user input	Stored as
String	Any characters until Enter	`42`	`"42"` (text, not the number 42)
Integer	Only digits (and optional sign)	`42`	`42` (the number)
Float	Digits with decimal point	`3.14`	`3.14` (the number)
