How to Pivot pandas for removing of some headers and renaming of some indexes

Question

I have the following pandas dataframe:

    count  event      date
0    1544  'strike'   2016-11-01
1     226  'defense'  2016-11-01
2    1524  'strike'   2016-12-01
3     246  'defense'  2016-12-01
4    1592  'strike'   2017-01-01
5     245  'defense'  2017-01-01

I want to pivot/transform it in such a way the final output looks like this:

event     2016-11-01 2016-12-01 2017-01-01 2017-02-01 2017-03-01                                                                     
'strike'        1544       1524       1592       1608       1654   
'defense'        226        246        245        210        254

but what i'm getting now upon pivoting is this:

                        count          count            count           count             count\
date          2016-11-01 2016-12-01 2017-01-01 2017-02-01 2017-03-01   
event                                                                  
'strike'            1544       1524       1592       1608       1654   
'defense'            226        246        245        210        254   

is there any way i could remove the entire empty row ahead of the event index-name and rename the date index-name with event as its index-name and also remove the unwanted countappearing in the first row of the data frame? The data seems to be transforming correctly i just want to get rid of these headers and indexes and have the renamed and removed properly. I also don't want the row labels in the desired output.

This is what i've been trying till now:

output = df.pivot(index='event', columns='date')
print(output)

Solution is add parameter values to pivot, then add reset_index for column from index and rename_axis fro remove column name:

output=df.pivot(index='event',columns='date',values='count').reset_index().rename_axis(None,1)
print(output)
       event  2016-11-01  2016-12-01  2017-01-01
0  'defense'         226         246         245
1   'strike'        1544        1524        1592

What happens if omit it?

print (df)
   count      event        date  count1
0   1544   'strike'  2016-11-01       1
1    226  'defense'  2016-11-01       7
2   1524   'strike'  2016-12-01       8
3    246  'defense'  2016-12-01       3
4   1592   'strike'  2017-01-01       0
5    245  'defense'  2017-01-01       1

pivot use each not used column and create MultiIndex for distinguish original columns:

output = df.pivot(index='event', columns='date')
print(output)
               count                           count1                      
date      2016-11-01 2016-12-01 2017-01-01 2016-11-01 2016-12-01 2017-01-01
event                                                                      
'defense'        226        246        245          7          3          1
'strike'        1544       1524       1592          1          8          0

I tried same but I am getting below error,

rename_axis() takes from 1 to 2 positional arguments but 3 were given

Can you please help me.

Hi, @saroj,

Set the name of the axis for the index or columns.

rename_axis(None,axis=1) instead of rename_axis(None,1)
