Python Pandas DataFrame.describe() function returns the statistics of a DataFrame.

pandas.DataFrame.describe()grammar

DataFrame.describe(
    percentiles=None, include=None, exclude=None, datetime_is_numeric=False
)

parameter

return

It returns a statistical summary of the passed Seriesor DataFrame.

Example Code: DataFrame.describe()Method to Find DataFrame Statistics

import pandas as pd

dataframe=pd.DataFrame({'Attendance': {0: 60, 1: 100, 2: 80,3: 78,4: 95},
                        'Name': {0: 'Olivia', 1: 'John', 2: 'Laura',3: 'Ben',4: 'Kevin'},
                        'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}})

print("The Original Data frame is: \n")
print(dataframe)

dataframe1 = dataframe.describe()
print("Statistics are: \n")
print(dataframe1)

Output:

The Original Data frame is: 

   Attendance    Name  Obtained Marks
0          60  Olivia              90
1         100    John              75
2          80   Laura              82
3          78     Ben              64
4          95   Kevin              45
Statistics are: 

       Attendance  Obtained Marks
count    5.000000        5.000000
mean    82.600000       71.200000
std     15.773395       17.484279
min     60.000000       45.000000
25%     78.000000       64.000000
50%     80.000000       75.000000
75%     95.000000       82.000000
max    100.000000       90.000000

This function returns a statistical summary of the DataFrame. We did not pass any arguments, so the function used all default values.

Sample code: DataFrame.describe()Method to find statistics for each column

We will use includethe parameter to find statistics for all columns.

import pandas as pd
dataframe=pd.DataFrame({'Attendance': {0: 60, 1: 100, 2: 80,3: 78,4: 95},
                        'Name': {0: 'Olivia', 1: 'John', 2: 'Laura',3: 'Ben',4: 'Kevin'},
                        'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}})
print("The Original Data frame is: \n")
print(dataframe)

dataframe1 = dataframe.describe(include='all')
print("Statistics are: \n")
print(dataframe1)

Output:

The Original Data frame is: 

   Attendance    Name  Obtained Marks
0          60  Olivia              90
1         100    John              75
2          80   Laura              82
3          78     Ben              64
4          95   Kevin              45
Statistics are: 

        Attendance   Name  Obtained Marks
count     5.000000      5        5.000000
unique         NaN      5             NaN
top            NaN  Kevin             NaN
freq           NaN      1             NaN
mean     82.600000    NaN       71.200000
std      15.773395    NaN       17.484279
min      60.000000    NaN       45.000000
25%      78.000000    NaN       64.000000
50%      80.000000    NaN       75.000000
75%      95.000000    NaN       82.000000
max     100.000000    NaN       90.000000

This function returns summary statistics for all columns in the DataFrame.

Sample code: DataFrame.describe()Method to find numeric column statistics

Now we will use excludethe parameter to find statistics only for numeric columns.

import pandas as pd

dataframe=pd.DataFrame({'Attendance': {0: 60, 1: 100, 2: 80,3: 78,4: 95},
                        'Name': {0: 'Olivia', 1: 'John', 2: 'Laura',3: 'Ben',4: 'Kevin'},
                        'Obtained Marks': {0: 90, 1: 75, 2: 82, 3: 64, 4: 45}})
print("The Original Data frame is: \n")
print(dataframe)

dataframe1 = dataframe.describe(exclude=[object])
print("Statistics are: \n")
print(dataframe1)

Output:

The Original Data frame is: 

   Attendance    Name  Obtained Marks
0          60  Olivia              90
1         100    John              75
2          80   Laura              82
3          78     Ben              64
4          95   Kevin              45
Statistics are: 

       Attendance  Obtained Marks
count    5.000000        5.000000
mean    82.600000       71.200000
std     15.773395       17.484279
min     60.000000       45.000000
25%     78.000000       64.000000
50%     80.000000       75.000000
75%     95.000000       82.000000
max    100.000000       90.000000

We have excluded data types object.
