Is there an equivlent data type as the "struct" in C

Hi

I want to create a "struct" type variable array in Vizard. Each element in the array contains 5 sub-elements with different data type (i.e. string, int, float, etc.). Any suggestion? Thanks

I checked the Python website. It seems a similar structure to the "struct" in C would be the "list" or "dict". The "list" is more like an array in C, while the "dict" is similar to the "struct". However, I don't know how to combine the list and dict to make a struct array. Can anyone help me?

It sounds like you just want an array of custom class objects. The following code shows how to create a simple class and add instances of it to a list:

Code:

class MyStruct(object):

    def __init__(self,my_int,my_float,my_string):

        self.my_int = my_int

        self.my_float = my_float

        self.my_string = my_string



array = []

array.append( MyStruct(0,0.0,'foo') )

array.append( MyStruct(1,1.0,'bar') )



print array[0].my_string

Let me know if this isn't what you are looking for.

That's exactly what I want. Thank you.
