Replace comma with dot Pandas

Question

Given the following array, I want to replace commas with dots:

array([\'0,140711\', \'0,140711\', \'0,0999\', \'0,0999\', \'0,001\', \'0,001\',
       \'0,14         


        

Answer 1

If you are reading in with read_csv, you can specify how it interprets decimals with the decimal parameter.

e.g.

your_df = pd.read_csv('/your_path/your_file.csv',sep=';',decimal=',')

From the man pages:

thousands : str, optional Thousands separator.

decimal : str, default ‘.’ Character to recognize as decimal point (e.g. use ‘,’ for European data).
