The provided Python code is not valid due to the following reasons:

1. The variable `x` is assigned a value that contains a number and an undefined variable `z` without any operator between them. Python will raise a `SyntaxError` for this line.

2. The `^` operator in Python is not an exponentiation operator, it's a bitwise XOR operator. If you want to perform exponentiation, you should use the `**` operator.

3. The `//` operator in Python performs floor division. It's not clear from your code whether you want to divide the result of `x ^ x` by `2` before multiplying by `z`, or if you want to divide the result of `x ^ x * z` by `2`. Python's order of operations will perform multiplication and division from left to right, so currently your code will do the latter.

4. The `print(c)` statement will print the value of `c`, but `c` is not defined if the calculation in the previous line is not successful.

If you correct these issues, you can get a valid output from your code. For example, if you meant to square `x`, multiply by `z`, and then divide by `2`, you could write:

```python
x = 462231238978
z = 2
c = (x ** 2) * z // 2
print(c)
```

This will output a very large number, specifically `106974860168044717622272656684`.
