  1. Compare with 212.

Solution

Python
temp = float(input("Enter temperature in F: "))if temp >= 212:    print("Water is boiling")else:    print(f"Water is not boiling ({212 - temp:.0f} degrees to go)")
Outputtyped input: 190
Enter temperature in F: 190
Water is not boiling (22 degrees to go)

Line by line

Line 2

Smallest of three numbers

EasyIf-Else Programs · 61 of 64

Write a Python program to find the smallest of three numbers.

Input
A = 45, B = 23, C = 68
Output
Smallest: 23 | min(): 23

Approach

  1. Compare each with the other two using <=.

Solution

Python
a, b, c = 45, 23, 68if a <= b and a <= c:    smallest = aelif b <= c:    smallest = belse:    smallest = cprint("Smallest:", smallest, "| min():", min(a, b, c))
Output
Smallest: 23 | min(): 23

Line by line

Line 4

If a is not the smallest, only b and c remain to compare.

Monuments of a city

EasyIf-Else Programs · 59 of 64

Write a Python program that accepts a city name (Pune or Mumbai) and displays its monuments.

Input
Pune
Output
Enter city name: Pune
Shaniwar Wada
Lal Mahal
Sinhagad Fort

Approach

  1. Compare the city name and print the matching monuments.

Solution

Python
city = input("Enter city name: ").strip().title()if city == "Pune":    monuments = ["Shaniwar Wada", "Lal Mahal", "Sinhagad Fort"]elif city == "Mumbai":    monuments = ["Gateway of India", "Chhatrapati Shivaji Terminus", "Elephanta Caves"]else:    monuments = [] if monuments:    for m in monuments:        print(m)else:    print("No data for", city)
Outputtyped input: Pune
Enter city name: Pune
Shaniwar Wada
Lal Mahal
Sinhagad Fort

Line by line

Line 1

title() makes “pune” and “PUNE” match “Pune”.

Line 9

An empty list is falsy, so the else branch handles unknown cities.

Day name from a number

EasyIf-Else Programs · 58 of 64

Write a Python program that reads a number from 1 to 7 and prints the day (1 = Sunday, 2 = Monday, … 7 = Saturday).

Input
7
Output
Enter number: 7
Saturday

Approach

  1. Validate the range, then index into a list of day names.

Solution

Python
days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]n = int(input("Enter number: "))if 1 <= n <= 7:    print(days[n - 1])else:    print("Enter a number from 1 to 7")
Outputtyped input: 7
Enter number: 7
Saturday

Line by line

Line 4

List indexes start at 0, so subtract 1.

Tip

A list lookup replaces seven elif branches.

Python Practice › If-Else Programs › Program 57

Road tax by car price

EasyIf-Else Programs · 57 of 64

Write a Python program to display road tax: price below 5,00,000 pays 15,000; below 10,00,000 pays 50,000; below 15,00,000 pays 80,000.

Input
1200000
Output
450000 -> tax: 15000
1200000 -> tax: 80000
1800000 -> tax: not covered by these slabs

Approach

  1. Test the price bands from the lowest upwards.

Solution

Python
def road_tax(price):    if price < 500000:        return 15000    elif price < 1000000:        return 50000    elif price < 1500000:        return 80000    else:        return "not covered by these slabs" for price in [450000, 1200000, 1800000]:    print(price, "-> tax:", road_tax(price))
Output
450000 -> tax: 15000
1200000 -> tax: 80000
1800000 -> tax: not covered by these slabs

Line by line

Lines 2-7

Each elif only runs when the price is above the previous band.

Note

The original sample said a 12,00,000 car pays 50,000, but by the given rules prices from 10,00,000 to 15,00,000 pay 80,000.

Is the last digit divisible by 4?

EasyIf-Else Programs · 55 of 64

Write a Python program to check whether the last digit of a number is divisible by 4.

Input
58, 37
Output
58 -> last digit 8 is divisible by 4
37 -> last digit 7 is not divisible by 4

Approach

  1. Get the last digit with n % 10, then test % 4.

Solution

Python
for n in [58, 37]:    last = n % 10    if last % 4 == 0:        print(n, "-> last digit", last, "is divisible by 4")    else:        print(n, "-> last digit", last, "is not divisible by 4")
Output
58 -> last digit 8 is divisible by 4
37 -> last digit 7 is not divisible by 4

Line by line

Exam attendance eligibility

EasyIf-Else Programs · 54 of 64

Write a Python program that allows a student into the exam only if attendance is at least 75%.

Input
attended 52 of 65 classes, 40 of 65 classes
Output
80.0% -> eligible
61.5% -> not eligible

Approach

  1. Calculate the percentage, then compare with 75.

Solution

Python
for attended in [52, 40]:    total = 65    percent = attended / total * 100    if percent >= 75:        print(f"{percent:.1f}% -> eligible")    else:        print(f"{percent:.1f}% -> not eligible")
Output
80.0% -> eligible
61.5% -> not eligible

Line by line

Line 3

Percentage = attended / total × 100.

Line 5

:.1f prints one decimal place.

Absolute value

EasyIf-Else Programs · 53 of 64

Write a Python program to print the absolute value of a number.

Input
-1, 7
Output
-1 -> 1 | abs(): 1
7 -> 7 | abs(): 7

Approach

  1. If the number is negative, negate it; or use abs().

Solution

Python
for n in [-1, 7]:    if n < 0:        result = -n    else:        result = n    print(n, "->", result, "| abs():", abs(n))
Output
-1 -> 1 | abs(): 1
7 -> 7 | abs(): 7

Line by line

Lines 2-5

Negating a negative number makes it positive.

Line 6

The built-in abs() gives the same result.
