Replace values ​in a column with similar values ​in another column with different size - Python

Question

I have a dataframe with different values ​​in a column (about 6,000 rows), which I need to replace with similar (but differents) values ​​found in another dataframe, which has fewer rows.

Store	Values to replace
Store A 05/15/21	Store A
The Store B 04/01/21	Store B
Store letter B 11/12/21	Store C
Store C 10/24/21	Store D
Store D 09/30/21
the Store C 05/13/21
Store letter D 07/01/21
Store letter A 08/29/21

The goal is for the final dataframe to look like this:

Store
Store A
Store B
Store B
Store C
Store D
Store C
Store D
Store A

Answer 1

Given df and df2:

                     Store
0         Store A 05/15/21
1     The Store B 04/01/21
2  Store letter B 11/12/21
3         Store C 10/24/21
4         Store D 09/30/21
5     the Store C 05/13/21
6  Store letter D 07/01/21
7  Store letter A 08/29/21

  replace_values
0        Store A
1        Store B
2        Store C
3        Store D

Doing:

df.Store = df.Store.str.split()
df2.replace_values = df2.replace_values.str.split()
df.Store = df.Store.apply(lambda row: ' '.join(x for x in row if any(x in i for i in df2.replace_values)))
print(df)

Output:

     Store
0  Store A
1  Store B
2  Store B
3  Store C
4  Store D
5  Store C
6  Store D
7  Store A
