I have a dataframe with one column of last names, and one column of first names. How do I merge these columns so that I have one column with first and last names?
Here is what I have: First Name (Column 1)
John
Lisa
Jim
Last Name (Column 2)
Smith
Brown
Dandy
This is what I want:
Full Name
John Smith
Lisa Brown
Jim Dandy.
Thank you!
Try
df.assign(name = df.apply(' '.join, axis = 1)).drop(['first name', 'last name'], axis = 1)
You get
name
0 bob smith
1 john smith
2 bill smith
Here's a sample df:
df
first name last name
0 bob smith
1 john smith
2 bill smith
You can do the following to combine columns:
df['combined']= df['first name'] + ' ' + df['last name']
df
first name last name combined
0 bob smith bob smith
1 john smith john smith
2 bill smith bill smith
df["Full Name"] = df["First Name"] + ' ' + df["Last Name"]df.drop[["First Name", "Last Name"]], 1)
