Extract string/characters before a number using regex

I would like to extract everything that comes before a number using regex.

The dataframe below shows an example of what I want to do.

I want to extract everything that comes before the first number in the product_name column. The output column is what I want to get.

Thank you in advance!

product_name = ['Cashew Alm Classic 6/200g', 'Cashew Buttery Sprd 8/227g', 'Chives&Garlic 6/98g']
output = ['Cashew Alm Classic', 'Cashew Butter Sprd', 'Chives&Garlic']

data = pd.DataFrame(list(zip(product_name, output)), columns=['product_name', 'output'])

data

>Solution :

df['output2']=df['product_name'].str.extract(r'(.*?)\s(?=\d)')
df

#(.*?) : non-greedy capture everything
# \s: prior to space
# (?=\d) prior to a digit - positive lookahead

    product_name                output              output2
0   Cashew Alm Classic 6/200g   Cashew Alm Classic  Cashew Alm Classic
1   Cashew Buttery Sprd 8/227g  Cashew Butter Sprd  Cashew Buttery Sprd
2   Chives&Garlic 6/98g         Chives&Garlic       Chives&Garlic
