详解Python中heapq模块的用法
heapq.heappop is a function in Python's heapq module that removes and returns the smallest element from a heap. A heap is a special type of data structure that maintains the property that the smallest element is always at the top (i.e., the root of the tree).
The syntax for heapq.heappop is:
```python
heapq.heappop(heap)
```
Here, `heap` is the heap from which we want to remove the smallest element. The function modifies the heap in place and returns the smallest element.
If the heap is empty, heapq.heappop raises an IndexError.
