Apply a sequence of functions.<\/p>\n<p>The pipe method in Pandas is a powerful tool that can be used to chain multiple data transformation steps together. This can be very useful when you need to apply a series of changes to your data, as it can save you a lot of time and effort.<\/p>\n<p>To use the pipe method, you simply need to pass your data object to the <code>pipe()<\/code> function, followed by a list of functions that you want to apply to the data. The functions will be applied in the order that they are listed, and the output of each function will be passed to the next function in the chain.<\/p>\n<p>For example, if you have a DataFrame called <code>df<\/code> and you want to first filter the data by a certain column, then sort the data by another column, you could <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> use the following code:<\/p>\n<p><code>df = df.pipe(lambda df: df[df['column1'] == 'value1']).pipe(lambda df: df.sort_values('column2'))<\/code><\/p>\n<p>This code would first filter the DataFrame to only include rows where the value in the <code>column1<\/code> column is equal to <code>'value1'<\/code>.
