将单列column分成两列

▌Making separate columns from string

# importing pandas module  
import pandas as pd 
   
# reading csv file from url  
data = pd.read_csv("https://media.geeksforgeeks.org/wp-content/uploads/nba.csv") 
  
# dropping null value columns to avoid errors 
data.dropna(inplace = True) 
  
# new data frame with split value columns 
new = data["Name"].str.split(" ", n = 1, expand = True) 
  
# making separate first name column from new data frame 
data["First Name"]= new[0] 
  
# making separate last name column from new data frame 
data["Last Name"]= new[1] 
  
# Dropping old Name columns 
data.drop(columns =["Name"], inplace = True) 
  
# df display 
data
