How would this C struct be translated into Python

I'm pretty new to Python and I'm having difficulty figuring out how to use the structs. What would the C structs below look like when they are converted into Python?

These are the structs I have:

struct dataT
{
    int m;
};

struct stack
{
    int top;
    struct dataT items[STACKSIZE];
} st;

How would this statement be represented in Python?

st.items[st.top].m

You can use namedtuples to construct classes that can represent your structs:

from collections import namedtuple
dataT = namedtuple("dataT", ['m'])
stack = namedtuple("stack", ['top', 'items'])

st = stack(0, [])
st.items.append(dataT(5))
st.items[st.top].m

Though you will probably find that the stack class is unnecessary as pointed out list already has this behaviour.

You just need to define your dataT class

class dataT():
    def __init__(self, m=0):
        self.m = m

You can instantiate one like

d = dataT(5)

The stack behavior you can get from the list class already

>>> l = [dataT(i) for i in range(5)]
>>> l.pop().m
4
>>> l.pop().m
3
>>> l.pop().m
2
>>> l.pop().m
1
>>> l.pop().m
0
>>> l.append(dataT(3))
>>> l.pop().m
3
