# pandas.Series.str.slice_replace¶

Series.str.slice_replace(start=None, stop=None, repl=None)[source]

Replace a positional slice of a string with another value.

Parameters
startint, optional

Left index position to use for the slice. If not specified (None), the slice is unbounded on the left, i.e. slice from the start of the string.

stopint, optional

Right index position to use for the slice. If not specified (None), the slice is unbounded on the right, i.e. slice until the end of the string.

replstr, optional

String for replacement. If not specified (None), the sliced region is replaced with an empty string.

Returns
Series or Index

Same type as the original object.

Series.str.slice

Just slicing without replacement.

Examples

>>> s = pd.Series(['a', 'ab', 'abc', 'abdc', 'abcde'])
>>> s
0        a
1       ab
2      abc
3     abdc
4    abcde
dtype: object


Specify just start, meaning replace start until the end of the string with repl.

>>> s.str.slice_replace(1, repl='X')
0    aX
1    aX
2    aX
3    aX
4    aX
dtype: object


Specify just stop, meaning the start of the string to stop is replaced with repl, and the rest of the string is included.

>>> s.str.slice_replace(stop=2, repl='X')
0       X
1       X
2      Xc
3     Xdc
4    Xcde
dtype: object


Specify start and stop, meaning the slice from start to stop is replaced with repl. Everything before or after start and stop is included as is.

>>> s.str.slice_replace(start=1, stop=3, repl='X')
0      aX
1      aX
2      aX
3     aXc
4    aXde
dtype: object
