Vaex: replace single character in column names

I have a dataset with dot delimiter in column name, i.e. name_1.0. I understand that vaex changes these columns as name_1_0. I would like to use .drop() for my data frame. However, as I feel, it is not possible with column names that contain dot delimiter. How can I replace only one character in each column name? Is there an analog of pandas .columns ? I mean that in pandas it can be easily done by

df.columns = df.columns.str.replace(',', '_')

but it is quite impossible in my case (I have >50 columns) to use df.rename and explicitly change every column with dot delimiter

Since you know how you want to update each column name, you can loop over the column names and call the df.rename method:

for column_name in df.column_names:
   new_column_name = column_name.replace(",", "_")
   df.rename(column_name, new_column_name)
