pandas.Series.str.slice_replace

Series.str.slice_replace(self, start=None, stop=None, repl=None)

Replace a positional slice of a string with another value.

Parameters:

start : int, 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.

stop : int, 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.

repl : str, 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.

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
