Python: Find common divisors between two numbers in a given pair
Python Basic - 1: Exercise-29 with Solution
Write a Python program to find common divisors between two numbers in a given pair.
def ngcd(x, y): i=1 while(i<=x and i<=y): if(x%i==0 and y%i == 0): gcd=i; i+=1 return gcd; def num_comm_div(x, y): n = ngcd(x, y) result = 0 z = int(n**0.5) i = 1 while( i <= z ): if(n % i == 0): result += 2 if(i == n/i): result-=1 i+=1 return result print("Number of common divisors: ",num_comm_div(2, 4)) print("Number of common divisors: ",num_comm_div(2, 8)) print("Number of common divisors: ",num_comm_div(12, 24))
Number of common divisors: 2 Number of common divisors: 2 Number of common divisors: 6

What is the difference between Python's list methods append and extend?
append: Appends object at the end.
x = [1, 2, 3] x.append([4, 5]) print (x)
[1, 2, 3, [4, 5]]
extend: Extends list by appending elements from the iterable.
x = [1, 2, 3] x.extend([4, 5]) print (x)
[1, 2, 3, 4, 5]
