example) I have to replace commercial with commercialUS. I have four rows with
commercial
12commercial21
commercialUS
commercialCA
expected output:
commercialUS
12commercialUS21
comemrcialUS
commercialCA
in the column. But i have to only replace commercial with commercialUS i.e only first two columns should be updated. If i use replace functions then all columns are getting updated. I should not include commercialUS and commercialCA.
