# Calculate average total range from given total range in python pandas

When working with data in Python using the pandas library, it is common to need to calculate the average total range from a given total range. In this article, we will explore three different ways to solve this problem.

## Method 1: Using the mean() function

The first method involves using the mean() function provided by pandas. This function calculates the average of a given series or column. To calculate the average total range, we can subtract the minimum value from the maximum value and then calculate the mean of the resulting series.

``````
import pandas as pd

# Create a sample dataframe
data = {'Total Range': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

# Calculate the average total range
average_total_range = (df['Total Range'].max() - df['Total Range'].min()).mean()

print("Average Total Range:", average_total_range)
``````

This method is simple and straightforward. However, it may not be the most efficient solution for large datasets as it involves calculating the maximum and minimum values twice.

## Method 2: Using the describe() function

The second method involves using the describe() function provided by pandas. This function generates descriptive statistics of a given series or column, including the mean. By accessing the mean value from the resulting series, we can calculate the average total range.

``````
import pandas as pd

# Create a sample dataframe
data = {'Total Range': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

# Calculate the average total range
average_total_range = df['Total Range'].describe()['max'] - df['Total Range'].describe()['min']

print("Average Total Range:", average_total_range)
``````

This method is more concise and avoids calculating the maximum and minimum values twice. However, it relies on the describe() function, which generates additional statistics that may not be needed in this specific case.

## Method 3: Using numpy

The third method involves using the numpy library in addition to pandas. By converting the series to a numpy array, we can use the ptp() function provided by numpy to calculate the total range. Then, we can calculate the mean of the resulting array to obtain the average total range.

``````
import pandas as pd
import numpy as np

# Create a sample dataframe
data = {'Total Range': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

# Calculate the average total range
average_total_range = np.ptp(df['Total Range']).mean()

print("Average Total Range:", average_total_range)
``````

This method leverages the power of numpy to calculate the total range efficiently. It avoids calculating the maximum and minimum values twice and provides a concise solution.

After evaluating the three methods, it can be concluded that Method 3, which uses numpy, is the best option. It provides an efficient and concise solution without unnecessary calculations. However, the choice of method may depend on the specific requirements and constraints of the problem at hand.
