concatenate two columns values pandas

I have a dataframe data :

Cluster OsId    BrowserId   PageId  VolumePred  ConversionPred  
255      7         11          17   1149582        4.0  
607     18         99          16   917224         8.0  
22       0         12          14   1073848        4.0  

I would like to add new column "OSBROWSER" which is the concatenation of two columns : OsId and BrowserId.

The result should be like this :

Cluster OsId    BrowserId   PageId  VolumePred  ConversionPred  OSBROWSER
255      7         11          17   1149582        4.0           (7, 11)
607     18         99          16   917224         8.0           (18, 99)
22       0         12          14   1073848        4.0           (0, 12)

I try like this :

data['OSBrowser'] =  data["OsId"] + data["BrowserId"]

But it gave me the sum of the two clumns values

Any idea please? thanks you

SOLUTION :

data['OSBrowser']  = list(zip(data.OsId, data.BrowserId))

>Solution :

I would convert the columns to string, I think that’s what you’re looking to do.

df = pd.DataFrame(((123, 456, 789), (98, 765, 432)), columns=('a', 'b', 'c'))

df['a_str'] = df['a'].astype(str)
df['b_str'] = df['b'].astype(str)

df['ab'] = df['a_str'] + df['b_str']

df then looks like this

     a    b    c a_str b_str      ab
0  123  456  789   123   456  123456
1   98  765  432    98   765   98765

Then you can just drop a_str and b_str

df = df[['a', 'b', 'c', 'ab']]
