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
