Data Cleaning How to split Pandas column

It has been sometime since i tried working in python

I have this data frame with many columns too many to name

  last/first    location    job    department
  smith john    Vancouver   A1     servers
  rogers steve  Toronto     A2     eng
  Rogers Dave   Toronto     A4     HR

how to I remove caps in the last/first column and also split the last/first column by " "?

goal

  last      first    location    job    department
  smith     john     Vancouver   A1     servers
  rogers    steve    Toronto     A2     eng
  rogers    dave     Toronto     A4     HR
  

>Solution :

IIUC, you could use str.lower and str.split:

df[['last', 'first']] = (df.pop('last/first')
                           .str.lower()
                           .str.split(n=1, expand=True)
                         )

output:

    location job department    last  first
0  Vancouver  A1    servers   smith   john
1    Toronto  A2        eng  rogers  steve
2    Toronto  A4         HR  rogers   dave
