Series.str.cat(others=None, sep=None, na_rep=None)
[source] -
Concatenate strings in the Series/Index with given separator.
Parameters: others : list-like, or list of list-likes
If None, returns str concatenating strings of the Series
sep : string or None, default None
na_rep : string or None, default None
If None, NA in the series are ignored.
Returns: concat : Series/Index of objects or str
Examples
When
na_rep
isNone
(default behavior), NaN value(s) in the Series are ignored.>>> Series(['a','b',np.nan,'c']).str.cat(sep=' ') 'a b c'
>>> Series(['a','b',np.nan,'c']).str.cat(sep=' ', na_rep='?') 'a b ? c'
If
others
is specified, corresponding values are concatenated with the separator. Result will be a Series of strings.>>> Series(['a', 'b', 'c']).str.cat(['A', 'B', 'C'], sep=',') 0 a,A 1 b,B 2 c,C dtype: object
Otherwise, strings in the Series are concatenated. Result will be a string.
>>> Series(['a', 'b', 'c']).str.cat(sep=',') 'a,b,c'
Also, you can pass a list of list-likes.
>>> Series(['a', 'b']).str.cat([['x', 'y'], ['1', '2']], sep=',') 0 a,x,1 1 b,y,2 dtype: object
