Pandas : TypeError: float() argument must be a string or a number

Question

I have a dataframe that contains

user_id    date       browser  conversion  test  sex  age  country
   1    2015-12-03       IE        1         0    M   32         


        

Answer 1

IIUC you need exclude column date also:

columns = [c for c in columns if c not in ["test", 'date']]

because error:

TypeError: float() argument must be a string or a number, not 'Timestamp'
