如何告诉 Pandas read_csv 使用多个空格作为分隔符而不是单个空格？

Question

I want to read in a Pandas dataframe from csv, where there are single whitespaces inside column names and the separators are multiple whitespaces. How can I tell Pandas to use only more than one consecutive whitespace as separator but ignore single whitespaces?

Answer 1

With specific regex pattern for sep= option:

df = pd.read_csv(sep='\s{2,}')

• \s{2,} - quantifier, matches any whitespace character between 2 and unlimited times, as many times as possible

Answer 2

another option that I actually use, which saves me some shift keypresses:

df = pd.read_csv('file.csv', sep='\s\s+')
