Replacing specific value on pandas with edited value of row-CodePudding

I need to replacing a specific selected value of row with value that has been edited, what method that I need to do this? For example, I need to replace only the value chosen that contains 'X KODYA' with a new value 'KOTA X'

For example:

 ---------------- 
|       A        |
 ---------------- 
| SURABAYA KODYA |
| JAKARTA        |
| KEDIRI KODYA   |
 ----------------

Into:

 ---------------- 
|       A        |
 ---------------- 
| KOTA SURABAYA  |
| JAKARTA        |
| KOTA KEDIRI    |
 ----------------

For now what I do is replacing it manually:

df['A'] = df['A'].str.replace('KEDIRI KODYA', 'KOTA KEDIRI').str.replace('SURABAYA KODYA', 'KOTA SURABAYA')

CodePudding user response：

Use a regex with a capturing group and str.replace:

df['A'] = df['A'].str.replace(r'(\w )\s KODYA', r'KOTA \1', regex=True)

output:

               A
0  KOTA SURABAYA
1        JAKARTA
2    KOTA KEDIRI
