I'm trying to find the same number of occurrences in both data frames This is a follow-up question for my previous question
I got 2 data frames

df1=pd.DataFrame([[1,None],[1,None,],[1,None],[1,'item_a'],[2,'item_a'],[2,'item_b'],[2,'item_f'],[3,'item_e'],[3,'item_e'],[3,'item_g'],[3,'item_h']],columns=['id','A'])
df2=pd.DataFrame([[1,'item_a'],[1,'item_b'],[1,'item_c'],[1,'item_d'],[2,'item_a'],[2,'item_b'],[2,'item_c'],[2,'item_d'],[3,'item_e'],[3,'item_f'],[3,'item_g'],[3,'item_h']],columns=['id','A'])

 df1
        id  A
    0   1   None
    1   1   None
    2   1   None
    3   1   item_a # id 1 has 1 occurrences in total in df1
    4   2   item_a
    5   2   item_b
    6   2   item_f #id 2 has 3 occurrences in total in df1(id 2 has 3 occurrences here)
    7   3   item_e
    8   3   item_e
    9   3   item_g
    10  3   item_h #id3 has 4 ccurrences in total in df1



df2
    id  A
0   1   item_a
1   1   item_b
2   1   item_c
3   1   item_d
4   2   item_a
5   2   item_b
6   2   item_c
7   2   item_d
8   3   item_e
9   3   item_f
10  3   item_g
11  3   item_h

I got an answer on how to find similarities by using

previous result:
d=pd.merge(df1,df2,how='inner')
        id  A
3   1   item_a # id 1 has 1 occurrences in total in d
4   2   item_a
5   2   item_b # id 2 has 2 occurrences in total in d(id 2 has 2 occurrences here which does not match all the occurrences(3) in df1)
7   3   item_e
8   3   item_e
9   3   item_g
10  3   item_h #id 3 has 4 occurrences in total in d

What I've tried to find same number of occurrences in both data frames:
d[d['id'].value_counts()==df1['id'].value_counts()]
Which gave me an error:Can only compare identically-labeled Series objects
I've also tried different things using rename to put a column name for value_counts and merge them but failed.

Match: Count of occurrences in df1 for an id match count of occurrences in result data frame d

        cnt_in_df1|cntin_d
for id1:     1    | 1  count #match => id 1 should be in the desired output.
for id2:     3    | 2  count #mismatch=> id 2 should not be in the desired output
for id3:     4    | 4  count #match => id 3 should be in the desired output.

My desired output for this question:

        id  count 
    0   1    1
    1   3    4
