How do I store multiple instances of a class objects in a list?
How do I bind a name to a type in Python? In Java, I would do something like this:
SliceField[] schemaElements = {
new SliceField("cust", SliceDB.INT),
new SliceField("name", SliceDB.STRING),
new SliceField("age", SliceDB.INT),
new SliceField("phone", SliceDB.STRING),
new SliceField("address", SliceDB.STRING)
}
How would I do that in Python?
As for 1), you just need a list.
schemaElements = [SliceField("cust", SliceDB.INT), ..., SliceField("address", SliceDB.STRING)]
Regarding 2), I am not exactly sure what you mean:
Should you mean making sure that a variable always has a certain type, there is (a) no (easy) way to do that and (b) it is discouraged (use Duck Typing instead).
Should you mean renaming types (like C typedef), just assign them (newName = typeName)
int and str are functions turning values into integers and strings respectively.You can do this in Python just as well as you can in Java:
class Test:
def __init__(self, a, b):
self.a = a
self.b = b
l = [Test(1, 2), Test(3, 4), Test("I declare", "a thumb war")]
l[0].a
>>> 1
l[2].b
>>> 'a thumb war'
You can do something like this:
schemaElements = [SliceField("cust", SliceDB.INT),....]
While doing so, make sure that the class SliceField has __init__ defined.
class SliceField(value,type):
def __init__(self, value, type):
self.value = value
self.type = type
# Define other class parameters
If you want SliceField to bind to some particular conditions, you will have to define it inside you class itself.
