How to use str.contains() in Pandas

To use the str.contains() method in Pandas, you can use the str attribute of a Pandas series, followed by the contains() method.

This method allows you to check if a string contains a specified substring, and returns a boolean series indicating whether each string in the series contains the substring.

Example

Here's an example of using the str.contains() method in Pandas:

main.py

import pandas as pd

# create a sample series
s = pd.Series(["apple", "banana", "orange", "pear"])

# check if each string in the series contains the substring "an"
s_contains = s.str.contains("an")

# display the result
print(s_contains)

This will check if each string in the series contains the substring "an", and return a boolean series indicating whether each string in the series contains the substring.

The output will be:

output

0    False
1     True
2    False
3    False
dtype: bool

The str.contains() method is a convenient way to check if a string contains a specified substring.

Conclusion

It returns a boolean series indicating whether each string in the series contains the substring, which you can use to filter the data in the series.
