If you have a multiple series and wanted to create a pandas DataFrame by appending each series as a columns to DataFrame, you can use concat() method. In
Output is also a series 0110000 120000 280000 370000 4200000 Name: salary, dtype: int64 So how do we uselocto add a new row? If we use a row index that doesn’t exist in the DataFrame, it will create a new row for us.
然而,直接在Series上使用 reset_index(inplace=True) 是不合适的,因为Series本身并不包含行索引的概念,它只有一个标签(索引)对应一个值。下面我将详细解释为什么不能在Series上使用 reset_index(inplace=True) 来创建DataFrame,并提供将Series转换为DataFrame的正确方法。 1. 为什么不能在Series上使用 reset_index(...

Dataframe是一种表格形式的数据结构,用于存储和处理结构化数据。它类似于关系型数据库中的表格,可以包含多行和多列的数据。Dataframe提供了丰富的操作和计算功能,方便用户进行数据清洗、转换和分析。 在Dataframe中,可以通过Drop列操作删除某一列数据。Drop操作可以使得Dataframe中的列数量减少,从而减小内存消耗。使用Drop...
