There are several float columns, I want to convert all of float columns into int.
prior to knowing the column names of those float columns, How do I convert all of them into int type in one line?

You could use a simple for loop for this:
# say df is the dataframe
for c in df.columns:
if df[c].dtype == np.float:
df[c] = df[c].astype(int)
You can select_dtypes first and round them and finally convert to Int64 using df.astype which supports Nullable Int dtype:
m = df.select_dtypes(np.number)
df[m.columns]= m.round().astype('Int64')
