How can I filter a Pandas Series based on conditions?

How can I filter a Pandas Series based on conditions?

You can filter a Pandas Series by using boolean indexing. For example, if you have a Series s, you can filter it like this: s[s > 10] to get all values greater than 10.

Can you show me an example with a Series of numbers?

Sure! Here's an example:

import pandas as pd

s = pd.Series([1, 5, 10, 15, 20])
filtered_s = s[s > 10]
print(filtered_s)

This will output the values 15 and 20.

What if I want to filter based on multiple conditions?

You can use the & operator for 'and' conditions or the | operator for 'or' conditions. For example:

filtered_s = s[(s > 10) & (s < 20)]

This will give you values between 10 and 20.

Is there a way to filter using a function?

Yes! You can use the apply method to filter based on a custom function. For example:

filtered_s = s[s.apply(lambda x: x % 2 == 0)]

This will filter the Series to include only even numbers.
