To use:

fromeasing_functionsimport*# For a duration 10 you will get the relevant output from start to enda=QuadEaseInOut(start=0, end=3, duration=10)
k=a.ease(4) # 4 is a number between 0 and the duration you specified#k is the returned value from start to end (0 to 3)k2=a(4) # the ease object can also be called directly, like a function# example plots:importnumpyasnpimportmatplotlib.pyplotasplta=BounceEaseInOut(start=3, end=1, duration=1)
b=BounceEaseIn(start=0, end=1)
c=BounceEaseOut(start=0, end=1)
x=np.arange(0, 1, 0.001)
y0=list(map(a, x))
y1=list(map(b, x))
y2=list(map(c, x))
plt.plot(x,y0)
plt.plot(x,y1)
plt.plot(x,y2)
