Remove “.0” from float series

I have a dataframe with values such as 164684564.0 (type is float 64)

I just want to remove all the “.0″s from these numbers

"{:g}".format

did not work and https://stackoverflow.com/a/38283006/16796767 did not work either

Another thing: I don’t want to convert in scientific numbers (I did it once but I don’t remember the code I used). I also tried something else which occurred “cannot use this on series” error

A magical working answer would be greatly appreciated :)

Answer

You can use the method astype from the class DataFrame:

>> df = pd.DataFrame([[1.0], [2.0], [3.0]], columns=['Pop'])

>> print(df)
   Pop
0  1.0
1  2.0
2  3.0

>> df = df.astype(int)

>> print(df)
   Pop
0    1
1    2
2    3
