how to drop dataframe in pandas?
提问by Debojyoti Dey
Tips are there for dropping column and rows depending on some condition. But I want to drop the whole dataframe created in pandas. like in R : rm(dataframe) or in SQL: drop table
有根据某些条件删除列和行的提示。但我想删除在Pandas中创建的整个数据框。就像在 R 中：rm(dataframe) 或在 SQL 中：drop table
This will help to release the ram utilization.
这将有助于释放 ram 利用率。

Generally creating a new object and binding it to a variable will allow the deletion of any object the variable previously referred to. del, mentioned in @EdChum's comment, removes both the variable and any object it referred to.
通常，创建新对象并将其绑定到变量将允许删除变量先前引用的任何对象。del，在@EdChum 的评论中提到，删除变量和它引用的任何对象。
This is an over-simplification, but it will serve.
这是一种过度简化，但它会起作用。
