Python 删除 dataframe 列中的特定字符串

Question

I have a df with a one specific column like this:

var
100 asc
200 asc
150 asc
75  asc

I want to remove asc and retain as number so to get

var
100
200
150
75

Running

number =df['var'].replace('\asc',regex=True)

Yet nothing happens resulting df is exactly the same as the original one, yet no error are shown...

Any ideas?

Let us try

df['var'] = df['var'].str.strip(' asc')
