LIVE-1: Basic programming & bug-fixing in Python (for AI)

[AppliedAICourse]

SMALL ERROR: IN cell [19], in the line B[i, j] = A1[i, j] + A 2[i, j] worked without any errors as we have B=A1+A2 in cell [15]. This implies that we created B in the cell[15] and are simply overwriting it in cell[19]. If we did not have the line B=A1+A2 in cell [15], we would encounter and error in cell [19] as Python interpreter doesn't know what B is?
Anyways, the key lesson is the same: always allocate your variables before you use them in loops.

Great Session sir, Learnt a lot about how to avoid making mistakes by reading through error messages and documentation.

[subhodeepdas]

Thanks for this session. it is extremely helpful for us...Hope to see more such sessions like

[sunilsrivastava]

Thanks for such a nice initiative during lockdown.
Eagerly waiting for the next session.
Kudos to Applied AI Team :)

[shubhamjain]

This was a great session ....please make all subsequent videos public

[VinitNeogi]

Very useful session. Looking forward for next sessions

Hi, guys. This is really great course, you explain very clear, obvious, you love your work and teaching is yours. I will watch all your videos. One question regarding an example about rectangle. I think, the sides of rectangle may not be parallel to X and Y axes. It seems, you simplified it. IMHO.

[subhodeepdas]

Thanks Sir for this lessons.. I could not attend the live sessions but i will be watching all the videos in you tube for sure....Is it necessary to remember all the in built functions during programming or is it ok to take help from the internet

[bhargav]

Sir,
I think rectangle 2 points trick will only work if the rectangle's sides are parallel with axes.
Else there can be infinite number of rectangles.

The invalid syntax error at 1:23:45, is it showing in python3 or python2?

[pavankumar]

When should i watch these live videos after Sql (according to course) with the applied ai course or should i first learn complete applied ai course and then i need to watch it?

Sir, in Question:- Add two randomly generated NumPy 3D-matrices(tensor) using loops:-


A1 = np.random.rand(3, 4, 5)


A2 = np.random.rand(3, 4, 5)


(m, n, o) = A1.shape


B = np.zeros((3, 4, 5))

for i in range(m):
for j in range(n):
for k in range(o):
B(i, j, k) = A1(i, j, k) + A2(i, j, k)

print(B)


is giving this error....


File "<ipython-input-1-76c75788e2d6>", line 7
B(i, j, k) = A1(i, j, k) + A2(i, j, k)
^
SyntaxError: can't assign to function call



How to fix this error

[sunagshetty]

Hi sir, please do course on how to clear PCEP, PCAP, PCAPP certification exams, conducted by python institute.

[pallapothubhargavramfromib]

A1=np.random.rand(5, 4, 3)
A2=np.random.rand(5, 4, 3)
(r, c, x) = A1.shape;
B=np.zeros((5, 4, 3))
for i in range(r):
for j in range(c):
for k in range(x):

B[i, j, k]=A1[i, j, k]+A2[i, j, k]
print(B)
sir i have written the code like this given in assigenement is this correct plz let me know

[saikumarlokas]

Hi Sir, I have tried to get rid of this error but unable to solve it still facing same error:


def FindPoint(cx, cy, r, px, py):
cx = float(cx);
cy = float(cy);
r = float(r);
px = float(px);
py = float(py);
cx, cy, r, px, py = input("Enter cx, cy, r, px, py:").split();
print(cx, cy, r, px, py);


import math
d = math.sqrt( (cx-px)**2 + (cy-py)**2 )
print(d);

if d<r:
print("p in c")
else:
print("p is not in c")

FindPoint(1, 2, 3, 4, 5);
Enter cx, cy, r, px, py:0.0 0.0 5.0 1.0 1.0
0.0 0.0 5.0 1.0 1.0




facing same error :



TypeError Traceback (most recent call last)

in FindPoint(cx, cy, r, px, py)

---> 12 d = math.sqrt( (cx-px)**2 + (cy-py)**2 )
13 print(d);

Sir how can we make ds algos stronger parallely with the course do you guide us for it.
