Python | Pandas Series.ptp()

Pandas series is a One-dimensional ndarray with axis labels. The labels need not be unique but must be a hashable type. The object supports both integer- and label-based indexing and provides a host of methods for performing operations involving the index.

Pandas Series.ptp() function returns the difference between the maximum value and the
minimum value in the object. This is the equivalent of the numpy.ndarray method ptp.

Syntax: Series.ptp(axis=None, skipna=None, level=None, numeric_only=None, **kwargs)



Parameter :
axis : Axis for the function to be applied on.
skipna : Exclude NA/null values when computing the result.
level : If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar.
numeric_only : Include only float, int, boolean columns. If None, will attempt to use everything, then use only numeric data. Not implemented for Series.
**kwargs : Additional keyword arguments to be passed to the function.

Returns : ptp : scalar or Series (if level specified)

Example #1: Use Series.ptp() function to return the difference between the maximum and the minimum value of the underlying data in the given Series object.

sr = pd.Series([10, 25, 3, 11, 24, 6])
  
# Create the Index
index_ = ['Coca Cola', 'Sprite', 'Coke', 'Fanta', 'Dew', 'ThumbsUp']
  
# set the index
sr.index = index_
  
# Print the series
print(sr)

Output :

Now we will use Series.ptp() function to find the difference between the max and min value in the given series object.

Output :

Now we will use Series.ptp() function to find the difference between the max and min value in the given series object. we are going to skip the missing values in the calculation.
