Series.str.endswith(pat, na=nan) [source] Return boolean Series indicating whether each string in the Series/Index ends with passed pattern. Equivalent to str.endswith(). Parameters: pat : string Character sequence na : bool, default NaN Returns: endswith : Series/array of boolean values

Series.str.encode(encoding, errors='strict') [source] Encode character string in the Series/Index using indicated encoding. Equivalent to str.encode(). Parameters: encoding : str errors : str, optional Returns: encoded : Series/Index of objects

Series.str.decode(encoding, errors='strict') [source] Decode character string in the Series/Index using indicated encoding. Equivalent to str.decode() in python2 and bytes.decode() in python3. Parameters: encoding : str errors : str, optional Returns: decoded : Series/Index of objects

Series.str.count(pat, flags=0, **kwargs) [source] Count occurrences of pattern in each string of the Series/Index. Parameters: pat : string, valid regular expression flags : int, default 0 (no flags) re module flags, e.g. re.IGNORECASE Returns: counts : Series/Index of integer values

Series.str.contains(pat, case=True, flags=0, na=nan, regex=True) [source] Return boolean Series/array whether given pattern/regex is contained in each string in the Series/Index. Parameters: pat : string Character sequence or regular expression case : boolean, default True If True, case sensitive flags : int, default 0 (no flags) re module flags, e.g. re.IGNORECASE na : default NaN, fill value for missing values. regex : bool, default True If True use re.search, otherwise use Python

Series.str.center(width, fillchar=' ') [source] Filling left and right side of strings in the Series/Index with an additional character. Equivalent to str.center(). Parameters: width : int Minimum width of resulting string; additional characters will be filled with fillchar fillchar : str Additional character for filling, default is whitespace Returns: filled : Series/Index of objects

Series.str.cat(others=None, sep=None, na_rep=None) [source] Concatenate strings in the Series/Index with given separator. Parameters: others : list-like, or list of list-likes If None, returns str concatenating strings of the Series sep : string or None, default None na_rep : string or None, default None If None, NA in the series are ignored. Returns: concat : Series/Index of objects or str Examples When na_rep is None (default behavior), NaN value(s) in the Series are ignored. >

Series.str.capitalize() [source] Convert strings in the Series/Index to be capitalized. Equivalent to str.capitalize(). Returns: converted : Series/Index of objects

Series.str() [source] Vectorized string functions for Series and Index. NAs stay NA unless handled otherwise by a particular method. Patterned after Python?s string methods, with some inspiration from R?s stringr package. Examples >>> s.str.split('_') >>> s.str.replace('_', '')

Series.std(axis=None, skipna=None, level=None, ddof=1, numeric_only=None, **kwargs) [source] Return sample standard deviation over requested axis. Normalized by N-1 by default. This can be changed using the ddof argument Parameters: axis : {index (0)} skipna : boolean, default True Exclude NA/null values. If an entire row/column is NA, the result will be NA level : int or level name, default None If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing into
