pandas.Series.str.slice_replace

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

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.

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
