Example #1: Use get() function to extract a column out of the dataframe




# importing pandas as pd
import pandas as pd
  
# Creating the dataframe 
df = pd.read_csv("nba.csv")
  
# Print the dataframe
df

Output :

Now apply the get() function. We are going to extract the “Salary” column from the dataframe.




# applying get() function 
df.get("Salary")

Output :

Notice, the output is not a dataframe but a pandas series object.
 
Example #2: Use get() function to extract multiple columns at a time in random order




# importing pandas as pd
import pandas as pd
  
# Creating the dataframe 
df = pd.read_csv("nba.csv")
  
df.get(["Salary", "Team", "Name"])

Output :

A dataframe is returned as output. The ordering of the columns is not according to the actual dataframe but it follows the ordering that we provided to it in the function input.
