partition(self, sep=' ', expand=True)
This method splits the string at the first occurrence of sep
, and returns 3 elements containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return 3 elements containing the string itself, followed by two empty strings.
String to split on.
If True, return DataFrame/MultiIndex expanding dimensionality. If False, return Series/Index.
Split the string at the first occurrence of sep
.
Series.str.split
Split strings around given separators.
rpartition
Split the string at the last occurrence of :None:None:`sep`
.
str.partition
Standard library version.
>>> s = pd.Series(['Linda van der Berg', 'George Pitt-Rivers'])This example is valid syntax, but we were not able to check execution
... s 0 Linda van der Berg 1 George Pitt-Rivers dtype: object
>>> s.str.partition() 0 1 2 0 Linda van der Berg 1 George Pitt-Rivers
To partition by the last space instead of the first one:
This example is valid syntax, but we were not able to check execution>>> s.str.rpartition() 0 1 2 0 Linda van der Berg 1 George Pitt-Rivers
To partition by something different than a space:
This example is valid syntax, but we were not able to check execution>>> s.str.partition('-') 0 1 2 0 Linda van der Berg 1 George Pitt - Rivers
To return a Series containing tuples instead of a DataFrame:
This example is valid syntax, but we were not able to check execution>>> s.str.partition('-', expand=False) 0 (Linda van der Berg, , ) 1 (George Pitt, -, Rivers) dtype: object
Also available on indices:
This example is valid syntax, but we were not able to check execution>>> idx = pd.Index(['X 123', 'Y 999'])
... idx Index(['X 123', 'Y 999'], dtype='object')
Which will create a MultiIndex:
This example is valid syntax, but we were not able to check execution>>> idx.str.partition() MultiIndex([('X', ' ', '123'), ('Y', ' ', '999')], )
Or an index with tuples with expand=False
:
>>> idx.str.partition(expand=False) Index([('X', ' ', '123'), ('Y', ' ', '999')], dtype='object')See :

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
