pandas.Series.str.slice

Series.str.slice(start=None, stop=None, step=None)

Slice substrings from each element in the Series or Index.

Slicing substrings from strings in a Series or Index helps extract specific portions of data, making it easier to analyze or manipulate text. This is useful for tasks like parsing structured text fields or isolating parts of strings with a consistent format.

Parameters:

startint, optional

Start position for slice operation.

stopint, optional

Stop position for slice operation.

stepint, optional

Step size for slice operation.

Returns:

Series or Index of object

Series or Index from sliced substring from original string object.

Series.str.slice_replace

Replace a slice with a string.

Series.str.get

Return element at position. Equivalent to Series.str.slice(start=i, stop=i+1) with i being the position.

Examples

>>> s = pd.Series(["koala", "dog", "chameleon"])
>>> s
0        koala
1          dog
2    chameleon
dtype: object

>>> s.str.slice(start=1)
0        oala
1          og
2    hameleon
dtype: object

>>> s.str.slice(start=-1)
0           a
1           g
2           n
dtype: object

>>> s.str.slice(stop=2)
0    ko
1    do
2    ch
dtype: object

>>> s.str.slice(step=2)
0      kaa
1       dg
2    caeen
dtype: object

>>> s.str.slice(start=0, stop=5, step=3)
0    kl
1     d
2    cm
dtype: object

Equivalent behaviour to:

>>> s.str[0:5:3]
0    kl
1     d
2    cm
dtype: object
