string

capitalize(S) Return a copy of the string S with only its first character capitalized. |

string

center(S, width, fillchar=...) Return S centered in a string of length width. Padding is done using the specified fill character (default is a space) |

int

count(S, sub, start=..., end=...) Return the number of non-overlapping occurrences of substring sub in string S[start:end]. Optional arguments start and end are interpreted as in slice notation. |

object

decode(S, encoding=..., errors=...)
Decodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme. Default is 'strict' meaning that encoding errors raise a UnicodeDecodeError. Other possible values are 'ignore' and 'replace' as well as any other name registered with codecs.register_error that is able to handle UnicodeDecodeErrors.

object

encode(S, encoding=..., errors=...)
Encodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme. Default is 'strict' meaning that encoding errors raise a UnicodeEncodeError. Other possible values are 'ignore', 'replace' and 'xmlcharrefreplace' as well as any other name registered with codecs.register_error that is able to handle UnicodeEncodeErrors.

bool

endswith(S, suffix, start=..., end=...) Return True if S ends with the specified suffix, False otherwise. With optional start, test S beginning at that position. With optional end, stop comparing S at that position. suffix can also be a tuple of strings to try. |

string

expandtabs(S, tabsize=...) Return a copy of S where all tab characters are expanded using spaces. If tabsize is not given, a tab size of 8 characters is assumed. |

int

find(S, sub, start=... , end=...) Return the lowest index in S where substring sub is found, such that sub is contained within S[start:end]. Optional arguments start and end are interpreted as in slice notation. |

string

format(S, *args, **kwargs) Return a formatted version of S, using substitutions from args and kwargs. The substitutions are identified by braces ('{' and '}'). |

int

index(S, sub, start=... , end=...) Like S.find() but raise ValueError when the substring is not found. |

bool

isalnum(S) Return True if all characters in S are alphanumeric and there is at least one character in S, False otherwise. |

bool

isalpha(S) Return True if all characters in S are alphabetic and there is at least one character in S, False otherwise. |

bool

isdigit(S) Return True if all characters in S are digits and there is at least one character in S, False otherwise. |

bool

islower(S) Return True if all cased characters in S are lowercase and there is at least one cased character in S, False otherwise. |

bool

isspace(S) Return True if all characters in S are whitespace and there is at least one character in S, False otherwise. |

bool

istitle(S) Return True if S is a titlecased string and there is at least one character in S, i.e. uppercase characters may only follow uncased characters and lowercase characters only cased ones. Return False otherwise. |

bool

isupper(S) Return True if all cased characters in S are uppercase and there is at least one cased character in S, False otherwise. |

string

join(S, iterable) Return a string which is the concatenation of the strings in the iterable. The separator between elements is S. |

string

ljust(S, width, fillchar=...) Return S left-justified in a string of length width. Padding is done using the specified fill character (default is a space). |

string

lower(S) Return a copy of the string S converted to lowercase. |

string or unicode

lstrip(S, chars=...) Return a copy of the string S with leading whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping |

(head, sep, tail)

partition(S, sep) Search for the separator sep in S, and return the part before it, the separator itself, and the part after it. If the separator is not found, return S and two empty strings. |

string

replace(S, old, new, count=...) Return a copy of string S with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced. |

int

rfind(S, sub, start=... , end=...) Return the highest index in S where substring sub is found, such that sub is contained within S[start:end]. Optional arguments start and end are interpreted as in slice notation. |

int

rindex(S, sub, start=... , end=...) Like S.rfind() but raise ValueError when the substring is not found. |

string

rjust(S, width, fillchar=...) Return S right-justified in a string of length width. Padding is done using the specified fill character (default is a space) |

(head, sep, tail)

rpartition(S, sep) Search for the separator sep in S, starting at the end of S, and return the part before it, the separator itself, and the part after it. If the separator is not found, return two empty strings and S. |

list of strings

rsplit(S, sep=... , maxsplit=...) Return a list of the words in the string S, using sep as the delimiter string, starting at the end of the string and working to the front. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator. |

string or unicode

rstrip(S, chars=...) Return a copy of the string S with trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping |

list of strings

split(S, sep=... , maxsplit=...) Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result. |

list of strings

splitlines(S, keepends=False) Return a list of the lines in S, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true. |

bool

startswith(S, prefix, start=..., end=...) Return True if S starts with the specified prefix, False otherwise. With optional start, test S beginning at that position. With optional end, stop comparing S at that position. prefix can also be a tuple of strings to try. |

string or unicode

strip(S, chars=...) Return a copy of the string S with leading and trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is unicode, S will be converted to unicode before stripping |

string

swapcase(S) Return a copy of the string S with uppercase characters converted to lowercase and vice versa. |

string

title(S) Return a titlecased version of S, i.e. words start with uppercase characters, all remaining cased characters have lowercase. |

string

translate(S, table, deletechars=...) Return a copy of the string S, where all characters occurring in the optional argument deletechars are removed, and the remaining characters have been mapped through the given translation table, which must be a string of length 256 or None. If the table argument is None, no translation is applied and the operation simply removes the characters in deletechars. |

string

upper(S) Return a copy of the string S converted to uppercase. |

string

zfill(S, width) Pad a numeric string S with zeros on the left, to fill a field of the specified width. The string S is never truncated. |
