Description
Filled with simple resources and modules for a cleaner looking program, Usefulpy is a module filled with many useful functions and modules in various subjects geared to cut down and simplify some little bits of code that can become messy or repetitive.
Some are simple - like input validation and versatile type checking.
So instead of checking, say
float(x) == int(float(x))
You can check it as
is_integer(x)
Which calls
def is_integer(s):
'''Check if an object is an integer can be turned into an integer without
losing any value'''
try: return int(float(s)) == float(s)
except: return False
Other parts of the project are a little more complicated, including
quaternions
>>> from usefulpy.mathematics import quaternions
>>> quaternion(1, 2, 2, 2)
1+2i+2j+2k
>>> _*quaternion(2, 1, 1, 1)
-4+5i+5j+5k
>>>
Prime sieves
>>> from usefulpy.mathematics import Prime
>>> import timeit
>>> timeit.timeit('Prime(99999989)', number = 1000, globals = globals())
0.34076689999999843
>>> Prime(99999989)
True
Basic algebraic simplifier and derivative finder
>>> from usefulpy.mathematics import cos, x
>>> x+x
<mathfunc x*2 at 0x3a129d0>
>>> x*x
<mathfunc x**2 at 0x3a30100>
>>> x**x
<mathfunc x**x at 0x3a30118>
>>> _.derivative()
<mathfunc x**x+ln(x)*(x**x) at 0x3ca09a0>
>>> cos*2 == cos+cos
True
>>>
3d projection systems
Essentially, usefulpy is a large library of functions that improve the quality of python programming. One catch, it can't use any sort of third party libraries... so no numpy, scipy, manim, or any others...
