How can I search a pandas dataframe for the values in a specific column that meet multiple conditions on another column being True?

edit

To search a Pandas dataframe for values in a specific column that meet multiple conditions on another column being True, you can use the following code:

import pandas as pd

# create a sample dataframe
df = pd.DataFrame({'col1': ['A', 'B', 'C', 'D', 'E'],
                   'col2': [10, 20, 30, 40, 50],
                   'col3': [True, False, True, True, False]})

# search for values in col1 where col3 is True and col2 is greater than 20
result = df.loc[(df['col3'] == True) & (df['col2'] > 20), 'col1']

print(result)

Output:

2    C
3    D
Name: col1, dtype: object

In this example, we first create a sample dataframe with three columns. We then use the loc method to filter the dataframe by selecting rows where col3 is True and col2 is greater than 20. Finally, we select the values in col1 that meet both conditions. The resulting output is the values C and D in col1.
