Python pandas splitting text and numbers in dataframe












0















I have a dataframe df1 with column name Acc Number as the first column and the data looks like:



Acc Number
ASC100.1
MJT122
ASC120.4
XTY111


I need to make a new dataframe df2 that will have two columns first having the text part and the second having the numbers so the desired output is:



Text    Number 
ASC 100.1
MJT 122
ASC 100.4
XTY 111


How would I go about doing this?



Thanks!

          You could do something like this:



          import pandas as pd

          data = ['ASC100.1',
          'MJT122',
          'ASC120.4',
          'XTY111']

          df = pd.DataFrame(data=data, columns=['col'])

          result = df.col.str.extract('([a-zA-Z]+)([^a-zA-Z]+)', expand=True)
          result.columns = ['Text', 'Number']
          print(result)


          Output



            Text Number
          0 ASC 100.1
          1 MJT 122
          2 ASC 120.4
          3 XTY 111


          The pattern ([a-zA-Z]+)([^a-zA-Z]+) means match a group of letters: ([a-zA-Z]+) followed by a group of non letters: ([^a-zA-Z]+). A safer alternative will be to use the following regex: ([a-zA-Z]+)(d+.?d+) assuming the numbers can only have at most one point.



          Further




          1. The documentation on regex in Python.

          2. The documentation on extract.

          • Thanks Daniel, the str.extract worked, why would the regex be a safer option?

            Nov 13 '18 at 23:28











          • Because it will match only and only numbers with a possible point among them.
