Then we are trying to get the second value from the Series using the index. Allowed inputs are: A single label, e.g. name: object, optional. In order to find the index-only values, you can use the index function along with the series name and in return you will get all the index values as well as datatype of the index. Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric Python packages. Creating Pandas Series. Uses by default. DataFrame.loc. Just reset the index, without inserting it as a column in the new DataFrame. A pandas Series can be created using the following constructor − pandas.Series( data, index, dtype, copy) The parameters of the constructor are as follows − Example – Series Get Value by Index.

For a Series with a MultiIndex, only remove the specified levels from the index. pandas.Series.loc¶ property Series.loc¶. Access a group of rows and columns by label(s) or a boolean array..loc[] is primarily label based, but may also be used with a boolean array. The axis labels are collectively called index. fruits.index. pandas.Index.values¶ property Index.values¶. Removes all levels by default. ; Copy data, default is False. ; dtypes for data types. Access a single value for a row/column pair by integer position. Example Example. Access a group of rows and columns by label(s). drop: bool, default False. An example is given below. DataFrame.iat. It is a one-dimensional array holding data of any type. The first one using an integer index and the second using a string based index.
