Pandas Series kurt() Function:
Pandas kurtosis: The kurt() method of the Pandas Series gets the unbiased kurtosis over the given axis.
Syntax:
Series.kurt(axis=None, skipna=None, level=None, numeric_only=None)
Parameters
axis: This is optional. It indicates 0 or ‘index’. This is the axis on which the function will be applied.
skipna: This is optional. When computing the result, specify True to exclude NA/null values. The default value is True.
level: This is optional. It indicates the level (int or str). If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into a scalar. The level name is specified by str.
numeric_only: This is optional. Pass True to include just float, int, or boolean data. False by default
Return Value:
If a level is given, it returns a scalar or a series. The unbiased kurtosis over the given axis is returned by this kurt() method of the Pandas Series.

Pandas Series kurt() Function in Python
Example1
Approach:
Below is the implementation:
# Import pandas module using the import keyword.
import pandas as pd
# Import numpy module using the import keyword.
import numpy as np
idx = pd.MultiIndex.from_arrays([
['rand', 'rand', 'rand', 'rand',
'randn', 'randn', 'randn', 'randn']],
names=['DataType'])
x = pd.Series(np.append(np.random.rand(4),
np.random.randn(4)), index=idx)
print("The Series contains:")
print(x)
#kurtosis of all values in the series
print("\nx.kurt() returns:")
print(x.kurt())
#kurtosis of all values within given level
print("\nx.kurt(level='DataType') returns:")
print(x.kurt(level='DataType'))
print("\nx.kurt(level=0) returns:")
print(x.kurt(level=0))
Output:
Example2
Approach:
- Import pandas module using the import keyword.
- Pass some random key-value pair(dictionary), index list as arguments to the DataFrame() function of the pandas module to create a dataframe.
- Store it in a variable.
- Print the given dataframe.
- Apply kurt() function on the student_marks column of the dataframe to get the kurtosis of all the elements of the student_marks column and print the result.
-
The Exit of the Program.
Below is the implementation:
# Import pandas module using the import keyword.
import pandas as pd
# Pass some random key-value pair(dictionary), index list as arguments to the
# DataFrame() function of the pandas module to create a dataframe
# Store it in a variable.
data_frme = pd.DataFrame({
"student_rollno": [1, 2, 3, 4],
"student_marks": [80, 35, 25, 90]},
index= ["virat", "nick" , "jessy", "sindhu"]
)
# Print the given dataframe
print("The given Dataframe:")
print(data_frme)
print()
# Apply kurt() function on the student_marks column of the dataframe to
# get the kurtosis of all the elements of the student_marks column
# and print the result.
print("The kurtosis of all the elements of student_marks column of a dataframe:")
print(data_frme["student_marks"].kurt())
Output:
The given Dataframe:
student_rollno student_marks
virat 1 80
nick 2 35
jessy 3 25
sindhu 4 90
The kurtosis of all the elements of student_marks column of a dataframe:
