Python: module string

string | index /sw/lib/python2.5/string.py Module Docs

`A collection of string operations (most are no longer used).
Warning: most of the code you see here isn't normally used nowadays.
Beginning with Python 1.6, many of these functions are implemented as
methods on the standard string object. They used to be implemented by
a built-in module called strop, but strop is now obsolete itself.
Public module variables:
whitespace -- a string containing all characters considered whitespace
lowercase -- a string containing all characters considered lowercase letters
uppercase -- a string containing all characters considered uppercase letters
letters -- a string containing all characters considered letters
digits -- a string containing all characters considered decimal digits
hexdigits -- a string containing all characters considered hexadecimal digits
octdigits -- a string containing all characters considered octal digits
punctuation -- a string containing all characters considered punctuation
printable -- a string containing all characters considered printable`

Functions
`` |  | atof(s) `atof(s) -> float Return the floating point number represented by the string s.` atoi(s, base=10) `atoi(s [,base]) -> int Return the integer represented by the string s in the given base, which defaults to 10. The string s must consist of one or more digits, possibly preceded by a sign. If base is 0, it is chosen from the leading characters of s, 0 for octal, 0x or 0X for hexadecimal. If base is 16, a preceding 0x or 0X is accepted.` atol(s, base=10) `atol(s [,base]) -> long Return the long integer represented by the string s in the given base, which defaults to 10. The string s must consist of one or more digits, possibly preceded by a sign. If base is 0, it is chosen from the leading characters of s, 0 for octal, 0x or 0X for hexadecimal. If base is 16, a preceding 0x or 0X is accepted. A trailing L or l is not accepted, unless base is 0.` capitalize(s) `capitalize(s) -> string Return a copy of the string s with only its first character capitalized.` capwords(s, sep=None) `capwords(s, [sep]) -> string Split the argument into words using split, capitalize each word using capitalize, and join the capitalized words using join. Note that this replaces runs of whitespace characters by a single space.` center(s, width, *args) `center(s, width[, fillchar]) -> string Return a center version of s, in a field of the specified width. padded with spaces as needed. The string is never truncated. If specified the fillchar is used instead of spaces.` count(s, *args) `count(s, sub[, start[,end]]) -> int Return the number of occurrences of substring sub in string s[start:end]. Optional arguments start and end are interpreted as in slice notation.` expandtabs(s, tabsize=8) `expandtabs(s [,tabsize]) -> string Return a copy of the string s with all tab characters replaced by the appropriate number of spaces, depending on the current column, and the tabsize (default 8).` find(s, *args) `find(s, sub [,start [,end]]) -> in 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. Return -1 on failure.` index(s, *args) `index(s, sub [,start [,end]]) -> int Like find but raises ValueError when the substring is not found.` join(words, sep=' ') `join(list [,sep]) -> string Return a string composed of the words in list, with intervening occurrences of sep. The default separator is a single space. (joinfields and join are synonymous)` joinfields = join(words, sep=' ') `join(list [,sep]) -> string Return a string composed of the words in list, with intervening occurrences of sep. The default separator is a single space. (joinfields and join are synonymous)` ljust(s, width, *args) `ljust(s, width[, fillchar]) -> string Return a left-justified version of s, in a field of the specified width, padded with spaces as needed. The string is never truncated. If specified the fillchar is used instead of spaces.` lower(s) `lower(s) -> string Return a copy of the string s converted to lowercase.` lstrip(s, chars=None) `lstrip(s [,chars]) -> string Return a copy of the string s with leading whitespace removed. If chars is given and not None, remove characters in chars instead.` maketrans(...) `maketrans(frm, to) -> string Return a translation table (a string of 256 bytes long) suitable for use in string.translate. The strings frm and to must be of the same length.` replace(s, old, new, maxsplit=-1) `replace (str, old, new[, maxsplit]) -> string Return a copy of string str with all occurrences of substring old replaced by new. If the optional argument maxsplit is given, only the first maxsplit occurrences are replaced.` rfind(s, *args) `rfind(s, sub [,start [,end]]) -> int 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. Return -1 on failure.` rindex(s, *args) `rindex(s, sub [,start [,end]]) -> int Like rfind but raises ValueError when the substring is not found.` rjust(s, width, *args) `rjust(s, width[, fillchar]) -> string Return a right-justified version of s, in a field of the specified width, padded with spaces as needed. The string is never truncated. If specified the fillchar is used instead of spaces.` rsplit(s, sep=None, maxsplit=-1) `rsplit(s [,sep [,maxsplit]]) -> list of strings 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.` rstrip(s, chars=None) `rstrip(s [,chars]) -> string Return a copy of the string s with trailing whitespace removed. If chars is given and not None, remove characters in chars instead.` split(s, sep=None, maxsplit=-1) `split(s [,sep [,maxsplit]]) -> list of strings Return a list of the words in the string s, using sep as the delimiter string. If maxsplit is given, splits at no more than maxsplit places (resulting in at most maxsplit+1 words). If sep is not specified or is None, any whitespace string is a separator. (split and splitfields are synonymous)` splitfields = split(s, sep=None, maxsplit=-1) `split(s [,sep [,maxsplit]]) -> list of strings Return a list of the words in the string s, using sep as the delimiter string. If maxsplit is given, splits at no more than maxsplit places (resulting in at most maxsplit+1 words). If sep is not specified or is None, any whitespace string is a separator. (split and splitfields are synonymous)` strip(s, chars=None) `strip(s [,chars]) -> string 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.` swapcase(s) `swapcase(s) -> string Return a copy of the string s with upper case characters converted to lowercase and vice versa.` translate(s, table, deletions='') `translate(s,table [,deletions]) -> string Return a copy of the string s, where all characters occurring in the optional argument deletions are removed, and the remaining characters have been mapped through the given translation table, which must be a string of length 256. The deletions argument is not allowed for Unicode strings.` upper(s) `upper(s) -> string Return a copy of the string s converted to uppercase.` zfill(x, width) `zfill(x, width) -> string Pad a numeric string x with zeros on the left, to fill a field of the specified width. The string x is never truncated.`
