我正在尝试对整个列执行操作,但出现类型错误,我想创建一个包含Shapely Point 的列:
crime_df = crime_df[crime_df['Latitude'].notna()]
crime_df = crime_df[crime_df['Longitude'].notna()]
crime_df['Longitude'] = crime_df['Longitude'].astype(float)
crime_df['Latitude'] = crime_df['Latitude'].astype(float)
print (crime_df['Longitude'])
print (crime_df['Latitude'])
crime_df['point'] = Point(crime_df['Longitude'], crime_df['Latitude'])

if(Arrays.asList(results).contains("Word"));

我想在.contains参数中添加至少几个术语,但是我觉得在一行上有大量术语是不好的编程习惯.
我的问题是,是否有更合适的方法来存储我想要在.contains参数中的所有值?
谢谢

当我打开一个正常的命令提示符并运行相同的命令(asc-tree -v cs1.)时,它可以正常工作.
我在这里看了一下并尝试在我的环境变量中使用UNC表示法而不是"Z:\"但是这只是给了我与机器名而不是驱动器相同的错误.
我也尝试更改服务以使用我的帐户登录详细信息而不是"本地系统帐户",但似乎没有这样做.
有人有什么想法?
我有以下方法来更新 MongoDB 中的文档:
public async Task UpdateAsync(T entity)
{
await _collection.ReplaceOneAsync(filter => filter.Id == entity.Id, entity);
}

哪个工作正常 - 我只是想知道是否有人有这个UpdateManyAsync函数如何工作的例子:
public async Task UpdateManyAsync(IEnumerable<T> entities)
{
await _collection.UpdateManyAsync(); // What are the parameters here
