Pandas how to apply multiple functions to dataframe

Question

Is there a way to apply a list of functions to each column in a DataFrame like the DataFrameGroupBy.agg function does? I found an ugly way to do it like this:

Answer 1

I tried to apply three functions into a column and it works

#removing new line character
rem_newline = lambda x : re.sub('\n',' ',x).strip()

#character lower and removing spaces
lower_strip = lambda x : x.lower().strip()

df = df['users_name'].apply(lower_strip).apply(rem_newline).str.split('(',n=1,expand=True)
