Return List of Variable Names of pandas DataFrame in Python (Example Code)
In this tutorial, I’ll illustrate how to get column names in the Python programming language.
Preparing the Example
import pandas as pd # Import pandas library |
import pandas as pd # Import pandas library
my_df = pd.DataFrame({"A":["a", "n", "s", "d"], # Constructing DataFrame "B":range(11, 15), "C":range(1, 5), "D":["a", "b", "c", "d"], "E":[10, 20, 30, 40]}) print(my_df) # Displaying example data in Python # A B C D E # 0 a 11 1 a 10 # 1 n 12 2 b 20 # 2 s 13 3 c 30 # 3 d 14 4 d 40 |
my_df = pd.DataFrame({"A":["a", "n", "s", "d"], # Constructing DataFrame "B":range(11, 15), "C":range(1, 5), "D":["a", "b", "c", "d"], "E":[10, 20, 30, 40]}) print(my_df) # Displaying example data in Python # A B C D E # 0 a 11 1 a 10 # 1 n 12 2 b 20 # 2 s 13 3 c 30 # 3 d 14 4 d 40
Example: Return List of Column Names in Pythoin
columns_list = list(my_df) # Using list() function print(columns_list) # Returning list of variable names # ['A', 'B', 'C', 'D', 'E'] |
columns_list = list(my_df) # Using list() function print(columns_list) # Returning list of variable names # ['A', 'B', 'C', 'D', 'E']
