Python is a popular, widely-used programming language and easy to learn for beginners because of its short syntax and readability, and learning to code in python creates a lot of opportunities in today’s time. Practicing Programs in Python can help you become more familiar with the language and its syntax, which will make it easier for you to write and understand code in the future.<\/p>\n\n\n\n

60 fundamental Programs in Python<\/h2>\n\n\n\n

In this article, we will see 60 fundamental Programs in Python<\/a> i.e. Python programming examples that you must learn and solve as they will help you improve your problem-solving and critical thinking skills, and give you an idea of how you must break down complex problems into smaller, more manageable pieces and then find a solution for each piece.<\/p>\n\n\n\n

1. Python program to find the sum of elements<\/h3>\n\n\n\n

A list in python is like an array in any other programming language. We will write a Python program to find the sum of all elements of a list.<\/p>\n\n\n\n

43. Python program for Strong Number<\/h3>\n\n\n\n
A strong number is a number in which the sum of the factorials of its digits is equal to the number itself. For example, 145 is a strong number because 1! + 4! + 5! = 1 + 24 + 120 = 145.<\/p>\n\n\n\n

44. Python program to find Prime Factors of a number<\/h3>\n\n\n\n
The prime factors of a number are the prime numbers that divide the number completely. For example, the prime factors of 15 are 3 and 5, because 3 and 5 are prime numbers, and 3 x 5 = 15.<\/p>\n\n\n\n

n=15\ni=1\nprint(\"Factors:\")\nwhile(i<=n):\n    k=0\n    if(n%i==0):\n        j=1\n        while(j<=i):\n            if(i%j==0):\n                k=k+1\n            j=j+1\n        if(k==2):\n            print(i)\n    i=i+1<\/pre><\/div>\n\n\n\n
Output:<\/strong><\/p>\n\n\n\n
