In this program, we will be taking a password as a combination of alphanumeric characters along with special characters, and check whether the password is valid or not with the help of few conditions.
Primary conditions for password validation :
How to create a program to multiply two matrices in python.
Examples:
Input : X = [[1, 7, 3],
[3, 5, 6],
[6, 8, 9]]
Y = [[1, 1, 1, 2],
[6, 7, 3, 0],
[4, 5, 9, 1]]
Output : [55, 65, 49, 5]
[57, 68, 72, 12]
[90, 107, 111, 21]

Tuple is a collection of Python objects much like a list. The sequence of values stored in a tuple can be of any type, and they are indexed by integers.
[mai mult...]Method1:Using Yield
The yield keyword enables a function to comeback where it left off when it is called again
[mai mult...]We will see how can we remove an empty tuple from a given list of tuples.
[mai mult...]This is the easiest and the fastest way to clone a list.
[mai mult...]Given a number n, find whether all digits of n divide it or not.
Examples:
Input : 128 Output : Yes 128 % 1 == 0, 128 % 2 == 0, and 128 % 8 == 0. Input : 130 Output : No
We want to test whether each digit is non-zero and divides the number. For example, with 128, we want to test d != 0 && 128 % d == 0 for d = 1, 2, 8. To do that, we need to iterate over each digit of the number.
[mai mult...]Given A and B, the task is to find the number of possible values that X can take such that the given modular equation (A mod X) = B holds good. Here, X is also called a solution of the modular equation.
Examples:
Input : A = 26, B = 2
Output : 6
Explanation
X can be equal to any of {3, 4, 6, 8,
12, 24} as A modulus any of these values
equals 2 i. e., (26 mod 3) = (26 mod 4)
= (26 mod 6) = (26 mod 8) =Output:2
Input : 21 5
Output : 2
Explanation
X can be equal to any of {8, 16} as A modulus
any of these values equals 5 i.e. (21 mod
8) = (21 mod 16) = 5

Given a decimal number N, the task is to check if a number has consecutive zeroes or not after converting the number to its K-based notation.
Examples:
Input: N = 4, K = 2
Output: No
4 in base 2 is 100, As there are consecutive 2 thus the answer is No.
Input: N = 15, K = 8
Output: Yes
15 in base 8 is 17, As there are no consecutive 0 so the answer is Yes.
Conjecture: A conjecture is a proposition or conclusion based upon incompleate information to which no proof has been found i.e it has not been proved or disproved.
Mathematically,
there is always one prime p in the range 
to 
where n is any natural number.
for examples:
2 and 3 are the primes in the range 
to 
.
5 and 7 are the primes in the range to 
.
11 and 13 are the primes in the range to 
.
17 and 19 are the primes in the range to 
.
