In Python you might come throughout IndexError: index 2 is out of bounds for axis 0 with size 2 native time come time.

The error relates to the use of indexes and the no of columns you are referencing.

We discussed solitary positional indexer is out-of-bounds and also in that blog post, it was pertained to referencing indexes for rows that execute not exist.

In this blog post, the error relates come referencing the index for columns that execute not exist.

Lets walk through the password below and also where the difficulty arises

So let us refresh ourselves through the data that is in the excel CSV paper below:

Hi Sir,can friend please aid me through this?

_________________________________________import csvimport numpy together npfrom matplotlib income pyplot as plt

t0 = 0.0tf = 5000.0n = 5001dt = (tf-t0)/(n-1)t = np.linspace (t0,tf,n)g = 0.1Kp = -2.0Ti = 10Td = 0.0SP = 50.00h = np.zeros()fi = np.zeros()fo = np.zeros()h<0> = 50.0

f = open(‘lfsretunepiddat.csv’)csv_f = csv.reader(f)nline = 0

for field in csv_f: nline = nline + 1 fi = field<0>f.close()

for i in range (1,n): h = h + g*(fi – fo) * dt fo = fo + (Kp)*((1.0 + dt/Ti + Td/dt)*(SP – h) + (-1.0 – 2.0*Td/dt)*(SP – h) + Td/dt * (SP – h))

for i in variety (n): publish (t,h,fi,fo)
