How do pandas select rows based on conditions?
In Pandas, boolean indexing can be used to select rows based on conditions.
For example, suppose there is a DataFrame named df that contains the following data:
A B C
0 1 4 7
1 2 5 8
2 3 6 9
To select rows that meet the criteria, you can use one of the following methods:
- “Utilize boolean indexing:”
- Select rows from the dataframe where the value in column ‘A’ is greater than 1.
- The above code will return all rows that meet the condition df[‘A’] > 1.
- Utilize the loc method:
- filter the DataFrame rows where the value in column ‘A’ is greater than 1
- This method will return all rows that satisfy the condition df[‘A’] > 1.
You can choose any method and select actions based on different conditions, then proceed with further operations as needed.
