10 Basic Coding Problems with Solutions in Python

Today we solve 10 basic problems using python programming language, it’s very easy to learn, also a trending language today.

1. To Add Two Numbers

We’re currently practicing performing basic addition operations with two integer numbers.

firstNum = int(input("enter 1st num"))
secondNum = int(input("enter 2nd num"))
def sum (a,b):
    c = a+b
    return c
sum(firstNum, secondNum)

# input 5 , 6
# output 11

2. Convert Celsius To Fahrenheit

We can implement the formula for converting Celsius to Fahrenheit in Python code by using the expression (0°C × 9/5) + 32 = 32°F.

c_temp = int(input("Enter Celsius Temperature: ")) 
f_temp = ((c_temp*9)/5)+32
print("Fahrenheit:",f_temp)

# input 36
# output 96.8

3. Convert Kilometers To Miles

We know 1 kilometer is approximately equal to 0.62 miles, we can easily calculate the distance in miles by multiplying the distance in kilometers by 0.62.

def kmToMiles(km):
    return km*0.62
km = int(input("Enter Km: "))
print("Miles: ",kmToMiles(km))
# input 5
# output 3.1

4. Is A Number Positive Or Negative

We can easily determine whether a number is positive or negative using this logic: if the number is equal to or greater than zero, then it’s positive; otherwise, it’s negative.

def isPositive(num):
    check = "positive" if num >=0 else "negetive"
    return check
num = int(input("Enter number: "))
print(isPositive(num))

# input 2
# output positive
# input -3
# output negetive

5. Is A Number Even Or Odd

We can determine whether a number is even or odd by dividing it by 2 and checking the remainder (modulus). If the remainder is zero, then the number is even; otherwise, it’s odd.

def evenOrOdd(num):
    if num != 0:
        check = "even" if num%2==0 else "odd"
        return check
    else:
        return "not even or odd"
num = int(input("Enter number: "))
print(evenOrOdd(num))

# input 2
# output even
# input 3
# output odd

6. Find the Largest Number from a List

Here, we’re leveraging Python’s default function max(). Later on, we’ll explore implementing custom methods using loops or recursion.

numArray = [2,5,3,1,4]
print("max number is", max(numArray))

# input [2,5,3,1,4]
# output 5

7. Determine whether a year is a leap year or not

We can determine whether a year is a leap year by the following rules: if the year is divisible by 400, it’s a leap year. If it’s not divisible by 400 but divisible by 4 and not divisible by 100, then it’s also a leap year; otherwise, it’s not leap year.

def isLeapYear(year):
    if year%400==0 or (year%4==0 and year%100!=0):
        print("leap year")
    else:
        print("not leap year")
year = int(input("Enter Year: "))
isLeapYear(year)

# input 1996
# output leap year
# input 2300
# output not leap year

8. Find The Factorial Of A Number

The factorial of a non-negative integer 𝑛n, denoted by 𝑛!n!, is the product of all positive integers less than or equal to 𝑛n. For example:

𝑛!=𝑛×(𝑛−1)×(𝑛−2)×…×3×2×1n!=n×(n−1)×(n−2)×…×3×2×1

For instance, 5!=5×4×3×2×1=1205!=5×4×3×2×1=120.

def factorial(num):
    output=1
    while(num>1):
        output *= num
        num -= 1
    return output
num = int(input("Enter a number: "))
print(factorial(num))

# input 5
# output 120

9. Is A Number Prime Or Not

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number is only divisible by 1 and itself. For example, 2, 3, 5, 7, 11, and 13 are prime numbers because they cannot be divided evenly by any other numbers except 1 and themselves.
