Randomly selecting a vertex

[nez57]

Hi,

I am trying to randomly select a vertex between 0 and 55 from a cube in a list, and then modify the vertex

This is the code I have:

for i in range(0, len(listName)):
            rand = random.randint(0, 55)
            cmds.select(listName[i] + '.vtx[' + rand + ']')
            cmds.move(random.uniform(-0.25, 0.25), random.uniform(-0.3, 0.3), random.uniform(-0.4, 0.4))

'listName' being the object in the list I am selecting the vertex from

The error message I get is:

# TypeError: coercing to Unicode: need string or buffer, int found #

Thanks in advance

for item in listName:
    rand = str(random.randint(0, 55))
    cmds.move(random.uniform(-0.25, 0.25),
              random.uniform(-0.3, 0.3),
              random.uniform(-0.4, 0.4),
              item + '.vtx[' + rand + ']')

3 things:

dont use the range operator in vain if you must get the working index of list use enumerate and tuple unpacking.

python is not like mel, it doenst autocnvert things for you you must do so yourself so convert int to string. Either where you make it or later when you use it if you need the int elsewhere.

the last one is pure maya stuff, all maya commands take in a list as last unnamed variable, this si the selection you work on. Its faster for maya to actually do it like this than to, set (setting selections is quite computationally intensive) then querry the global selection list. It aslo costs less memory overhead as its one item in undo stack.
