Re: [Tutor] reverse diagonal

[Ashfaq]

>>> revdiag = [M[i][i] for i in [2, 1, 0]]
>>> revdiag
[9, 5, 1]

The reverse diag entries (that you are seeking to get) are not correct.
They should be M[0][2], M[1][1], M[2][0].
So the code could be --

revdiag = []
for i in [0, 1, 2]:
j = 2 - i
revdiag.append( M[i][j] )

I hope it helps.

Re: [Tutor] FW: (no subject)

Run your code 10,000 times. :)

points = []
for i in range(0, 1):

x=random.uniform(0,1)

y=random.uniform(0,1)

points.append ( (x, y) )


I hope it helps.

Re: [Tutor] [Python2.7] Convert (2,188,1) into (188,1)

[Ashfaq]

Is it a 3-item tuple?

Re: [Tutor] Probably a silly question: how to install lxml?

[Ashfaq]

Hi Mark
ModuleNotFoundError means the package is not installed.
Can you paste those red error message here? This can shed some light.

Sincerely
