Question
The following attributes of a DataFrame return a list of column names of thisDataFrame?
columns
shape
dtype
column
Solution
The attribute of a DataFrame that returns a list of column names is columns
.
Here is how you can get it:
-
Import pandas library: This is the first step where you import pandas library using the command
import pandas as pd
. -
Create or load a DataFrame: You can either create a DataFrame using pandas
pd.DataFrame()
function or you can load a DataFrame from a csv file usingpd.read_csv()
function. -
Get the column names: Once you have a DataFrame, you can get the list of column names using the
columns
attribute. For example, if your DataFrame is named asdf
, you can get the column names usingdf.columns
.
Here is an example:
import pandas as pd
# Create a DataFrame
df = pd.DataFrame({
'A': ['foo', 'bar', 'baz'],
'B': ['one', 'two', 'three'],
'C': ['x', 'y', 'z']
})
# Get the column names
print(df.columns)
This will output: Index(['A', 'B', 'C'], dtype='object')
Note: The shape
attribute returns a tuple representing the dimensionality of the DataFrame and the dtype
attribute returns the data type of the values in the DataFrame. The columns
attribute is the correct answer to your question.
