如何从链表中删除这些节点？

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def deleteNodes(head, target):
    # 处理头节点为目标节点的情况
    while head and head.val == target:
        head = head.next
    
    # 遍历链表，找到需要删除的节点的前一个节点
    curr = head
    while curr and curr.next:
        if curr.next.val == target:
            curr.next = curr.next.next
        else:
            curr = curr.next
    
    return head
