class Stack:
    def __init__(self):
        self.stack = []

    def push(self, item):
        self.stack.append(item)

    def pop(self):
        if not self.is_empty():
            return self.stack.pop()
        return None

    def peek(self):
        if not self.is_empty():
            return self.stack[-1]
        return None

    def is_empty(self):
        return len(self.stack) == 0


# Example usage:
my_stack = Stack()
my_stack.push(5)
my_stack.push(10)
my_stack.push(3)

# Peeking at the top element
top_element = my_stack.peek()
print(top_element)  # Output: 3
