Pandas remove parts of string after specified character sequence

Question

I would like to remove a part of a string from a value inside a dataframe, using pandas.

Value:

"transaction  DATUM 07.03.2019, 07.48 UHR1.TAN 246915 DATUM 14.10.2019, 09.03 UHR1.TAN 620955 Client Name"

What I want is to remove "DATUM 07.03.2019, 07.48 UHR1.TAN 246915 DATUM 14.10.2019, 09.03 UHR1.TAN 620955"

Expected result would be

 "transaction Client Name"

Answer 1

You can use replace function like this.

df["transaction"] = df["transaction"].str.replace(r"(?<=transaction\s).*(?=\sClient)", "")
