Read csv with always the 1st space as the separator-CodePudding

I want to read a file in pandas data frame, which looks like:

    label1 text more text
    label2 text some more text

into a dataframe, which looks like:

    label              text
    label1             text more text
    label2             text some more text

My text column is without the quotes and I want to specify the 1st space as the separator and ignore all the later spaces in text field

I tried with the regular expression, which matches 1st space as well as the whole string before the 1st space with https://regex101.com:

       query_data = pd.read_csv('data.txt', sep='^.*?(?=\ )', engine='python',\
               names = ['label', 'text'])

But, this gives all the labels as NaNs. Then, I realized it is matching the full string before space. How do I just specify the 1st space as the delimiter?

You can just read the csv and split it later on

df = df.col.str.split(' ', n =1, expand=True)
