pysics
What is it ?
pysics is a set of python tools that might be useful for engineers or physicists. It is composed of several python modules:
- Units: a basic implementation of physical units (with numpy support)
- Graph: a matplotlib interface for easier data and function plotting
- Arrays: a convenient way to handle sampled 1D-functions (with units)
- Physics: physical constants and some basic physics equations (a bit light for now…)
How do I install it ?
You don’t install it for now, you just download and put the .py files where you want to use them.
You will also need the following packages:
- python 3
- numpy
- sympy
- scipy
- matplotlib (for graph.py only)
How do I use it
Here are a few examples of how you could use pysics. These are just very short examples to give a rough idea of what each module does. More detailed examples are given in the wiki page of each sub-module.
Units
The following code:
from units import *
speed = 36*km/hr
mass = 3*kg
Ec = 1/2 * mass * speed**2
print("Ec =", Ec )
print("Ec =", Ec/J, 'J' )
will return :
Ec = 150.000 kg*m**2/s**2 [PHYS]
Ec = 150.0 J
pysics.units will also detect any dimension error. The module can work with numpy arrays.
For more examples, see Units dedicated page.
Graph
from graph import *
def myfunc(x): return 3*x**3+2
G = quickGraph(myfunc,2,10) # show plot of f between xmin = 2 and xmax = 10
This will display:
A graph can be easily edited:
G.title = "Awesome graph"
G.ylabel = "My ordinates"
G.ymax = 5000
G.show()
will display:
For more examples, see Graph dedicated page.
Arrays
One of the feature of Arrays module is to multiply (or any other operation) data sets with different samplings. The following graph is a visual representation of what Arrays can do: Power is the product of Current by Voltage.
For more details on how to use the Arrays module, see the Arrays dedicated wiki page.
Physics
The Physics module defines physical constants and some basic physical laws. For more examples, see Physics dedicated page.
