How to Filter Data with Pandas

You can use the conditional filtering feature of the pandas DataFrame object to filter data that meets certain criteria. Here are some commonly used filtering methods:

1. A DataFrame is a type of data structure used in programming to store and organize tabular data.

df[df['列名'] > 条件]

1. I would like to ask a question.
2. ask a question

df.query('列名 > 条件')

1. is within()
2. Is contained in()

df[df['列名'].isin(['值1', '值2', ...])]

1. Check if the string contains.
2. The function str.contains()

df[df['列名'].str.contains('字符串')]

These methods can be used alone or in combination to meet different screening needs.
