Write a Python program to count the total number of ages between 20 to 30 in a DataFrame

Input −

Assume, you have a DataFrame,

 Id Age 0 1 21 1 2 23 2 3 32 3 4 35 4 5 18

Output −

Total number of age between 20 to 30 is 2.

Solution

To solve this, we will follow the below approaches.

• Define a DataFrame

• Set the DataFrame Age column between 20,30. Store it in result DataFrame. It is defined below,

df[df['Age'].between(20,30)]

• Finally, calculate the length of the result.

Example

Let us see the following implementation to get a better understanding.

import pandas as pd data = {'Id':[1,2,3,4,5],'Age':[21,23,32,35,18]} df = pd.DataFrame(data) print(df) print("Count the age between 20 to 30") result = df[df['Age'].between(20,30)] print(len(result))

Output

 Id Age 0 1 21 1 2 23 2 3 32 3 4 35 4 5 18 Count the age between 20 to 30 2
