I'm trying to find the same number of occurrences in both data frames
This is a follow-up question for [my previous question][1]
<br>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'])
<br>

     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
        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
<br>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(does not match 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:
<br>`d[d['id'].value_counts()==df1['id'].value_counts()]`
<br>`Which gave me an error:Can only compare identically-labeled Series objects`
<br>I've also tried different things using rename to put a column name for value_counts and merge them but failed.

    My desired output for this question:
    
            id  count 
        0   1    1
        1   3    4
