Write a program in Python to print the elements in a series between a specific range

When working with Pandas Series, you often need to filter elements that fall within a specific range. Python provides several methods to accomplish this task efficiently.

Input − Assume, you have a series:

0    12
1    13
2    15
3    20
4    19
5    18
6    11

Output − The result for the elements between 10 to 15:

0    12
1    13
2    15
6    11

Using between() Method

The between() method is the most straightforward approach to filter elements within a range. It returns a boolean mask that can be used for indexing.

Example

import pandas as pd

values = [12, 13, 15, 20, 19, 18, 11]
data = pd.Series(values)

print("Original Series:")
print(data)
print("\nElements between 10 and 15:")
print(data[data.between(10, 15)])

Original Series:
0    12
1    13
2    15
3    20
4    19
5    18
6    11
dtype: int64

Elements between 10 and 15:
0    12
1    13
2    15
6    11
dtype: int64

Using Manual Filtering with isin()

This approach manually iterates through the series, collects matching values, and uses isin() to filter the original series.

Example

import pandas as pd

values = [12, 13, 15, 20, 19, 18, 11]
data = pd.Series(values)

# Create empty list to store matching values
filtered_values = []

# Iterate through series and collect values in range
for i in range(len(data)):
    if data[i] >= 10 and data[i] <= 15:
        filtered_values.append(data[i])

print("Filtered values:", filtered_values)
print("Series elements in range:")
print(data[data.isin(filtered_values)])

Filtered values: [12, 13, 15, 11]
Series elements in range:
0    12
1    13
2    15
6    11
dtype: int64

Using Boolean Indexing

You can also use direct boolean conditions to filter the series ?

import pandas as pd

values = [12, 13, 15, 20, 19, 18, 11]
data = pd.Series(values)

# Using boolean indexing
result = data[(data >= 10) & (data <= 15)]
print("Elements between 10 and 15:")
print(result)

Elements between 10 and 15:
0    12
1    13
2    15
6    11
dtype: int64

Comparison

Conclusion

The between() method is the most efficient and readable approach for filtering series elements within a range. Use boolean indexing for more complex filtering conditions.
