pandas.Series.describe   Series.describe(percentiles=None, include=None, exclude=None, datetime_is_numeric=False)[source]
 
Generate descriptive statistics. Descriptive statistics include those that summarize the central tendency, dispersion and shape of a dataset’s distribution, excluding NaN values. Analyzes both numeric and object series, as well as DataFrame column sets of mixed data types. The output will vary depending on what is provided. Refer to the notes below for more detail.  Parameters 
 
percentiles:list-like of numbers, optional


The percentiles to include in the output. All should fall between 0 and 1. The default is [.25, .5, .75], which returns the 25th, 50th, and 75th percentiles.  
include:‘all’, list-like of dtypes or None (default), optional


A white list of data types to include in the result. Ignored for Series. Here are the options:  ‘all’ : All columns of the input will be included in the output. A list-like of dtypes : Limits the results to the provided data types. To limit the result to numeric types submit numpy.number. To limit it instead to object columns submit the numpy.object data type. Strings can also be used in the style of select_dtypes (e.g. df.describe(include=['O'])). To select pandas categorical columns, use 'category' None (default) : The result will include all numeric columns.   
exclude:list-like of dtypes or None (default), optional,


A black list of data types to omit from the result. Ignored for Series. Here are the options:  A list-like of dtypes : Excludes the provided data types from the result. To exclude numeric types submit numpy.number. To exclude object columns submit the data type numpy.object. Strings can also be used in the style of select_dtypes (e.g. df.describe(exclude=['O'])). To exclude pandas categorical columns, use 'category' None (default) : The result will exclude nothing.   
datetime_is_numeric:bool, default False


Whether to treat datetime dtypes as numeric. This affects statistics calculated for the column. For DataFrame input, this also controls whether datetime columns are included by default.  New in version 1.1.0.     Returns 
 Series or DataFrame

Summary statistics of the Series or Dataframe provided.      See also  DataFrame.count

Count number of non-NA/null observations.  DataFrame.max

Maximum of the values in the object.  DataFrame.min

Minimum of the values in the object.  DataFrame.mean

Mean of the values.  DataFrame.std

Standard deviation of the observations.  DataFrame.select_dtypes

Subset of a DataFrame including/excluding columns based on their dtype.    Notes For numeric data, the result’s index will include count, mean, std, min, max as well as lower, 50 and upper percentiles. By default the lower percentile is 25 and the upper percentile is 75. The 50 percentile is the same as the median. For object data (e.g. strings or timestamps), the result’s index will include count, unique, top, and freq. The top is the most common value. The freq is the most common value’s frequency. Timestamps also include the first and last items. If multiple object values have the highest count, then the count and top results will be arbitrarily chosen from among those with the highest count. For mixed data types provided via a DataFrame, the default is to return only an analysis of numeric columns. If the dataframe consists only of object and categorical data without any numeric columns, the default is to return an analysis of both the object and categorical columns. If include='all' is provided as an option, the result will include a union of attributes of each type. The include and exclude parameters can be used to limit which columns in a DataFrame are analyzed for the output. The parameters are ignored when analyzing a Series.
