Vectors2D

It's a small module called to facilitate work with vectors in Python. Adds class Vector2D and operations with vectors in 2 dimensions. All functions take Vector2D. They also take tuples or lists of int or float with len == 2. Vectors can be added, subbed, multiplied by other vector or by int/float and more. You can find all the functions of the module below.

Installing

Simply run pip install vectors2d from your command line.

Class:

Vector2D : takes ints, floats, tuple, list when creating. If not given, creates zero vector (0;0). If given only one number, assigns it to "x" coordinate. Also can take other Vector2D object.

Class methods:

1. is_zero() : check if vector is a zero vector.
2. is_parallel_to(vector) : check if the vector is parallel to the given vector. Takes Vector2D, list ot tuple.
3. is_perpendicular_to(vector) : check if the vector is perpendicular to the given vector. Takes Vector2D, list ot tuple.
4. is_codirectional_to(vector) : check if vector is co-directional to the given vector. Takes Vector2D, list ot tuple.

Global functions:

1. absolute_vector(vector) : calculates an absolute value of given vector. Takes Vector2D object, list or tuple. Returns float;
2. sum_vectors(*vectors) : returns the sum of all the given vectors. Takes Vector2D objects, lists and tuples in any combination. Returns Vector2D;
3. sub_vectors(*vectors) : returns the subtraction of all the given vectors. Takes Vector2D objects, lists and tuples in any combination. Returns Vector2D;
4. mult_vector(vector, multiplier) : returns the multiplication of the given vector by the given number (can be int or float). "vector" takes Vector2D object, list and tuple as vector; "multiplier" takes int and float as multiplier. Returns Vector2D;
5. scalar_mult_vectors(vectors*) : calculates a scalar multiplication of the given vectors. Takes Vector2D objects, lists and tuples in any combination. Returns float;
6. get_angle(vector1, vector2) : returns the angle between the two given vectors in radians. Takes Vector2D objects, lists and tuples in any combination. Returns float;
7. vector_from_dots(dot1, dot2) : calculates a vector from the two given dots. Returns Vector2D.
