np
"np" is most commonly used in computer science to refer to "nondeterministic polynomial time," a complexity class used to classify decision problems in computational theory. It includes problems for which a potential solution can be checked for correctness, given the right information, in polynomial time. However, the time it takes to find that solution can vary. In the context of programming languages, particularly Python, "np" is often used as an abbreviation for NumPy. NumPy is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions.

NP
In computational complexity theory, NP is one of the most fundamental complexity classes. The abbreviation NP refers to "nondeterministic polynomial time." Intuitively, NP is the set of all decision problems for which the instances where the answer is "yes" have efficiently verifiable proofs of the fact that the answer is indeed "yes". More precisely, these proofs have to be verifiable in polynomial time by a deterministic Turing machine. In an equivalent formal definition, NP is the set of decision problems where the "yes"-instances can be accepted in polynomial time by a non-deterministic Turing machine. The equivalence of the two definitions follows from the fact that an algorithm on such a non-deterministic machine consists of two phases, the first of which consists of a guess about the solution, which is generated in a non-deterministic way, while the second consists of a deterministic algorithm that verifies or rejects the guess as a valid solution to the problem. The complexity class P is contained in NP, but NP contains many important problems, the hardest of which are called NP-complete problems, for which no polynomial-time algorithms are known for solving them. The most important open question in complexity theory, the P = NP problem, asks whether polynomial time algorithms actually exist for NP-complete, and by corollary, all NP problems. It is widely believed that this is not the case.
The New Hacker's Dictionary
NP
Extremely. Used to modify adjectives describing a level or quality of difficulty; the connotation is often ‘more so than it should be’. This is generalized from the computer-science terms NP-hard and NP-complete; NP-complete problems all seem to be very hard, but so far no one has found a proof that they are. NP is the set of Nondeterministic-Polynomial problems, those that can be completed by a nondeterministic Turing machine in an amount of time that is a polynomial function of the size of the input; a solution for one NP-complete problem would solve all the others. “Coding a BitBlt implementation to perform correctly in every case is NP-annoying.”Note, however, that strictly speaking this usage is misleading; there are plenty of easy problems in class NP. NP-complete problems are hard not because they are in class NP, but because they are the hardest problems in class NP.
