Trimmed documentation of standard Python modules string, random, and math.... 

Trimmed documentation of standard Python modules string, random, and math. It's too much work to try and track these. Better to just point users to official Python docs rather than transcribing them.

The 'math' module provides trigonometric and other math
functions. It is a standard Python module.
Functions
acos(x) -- Return the arc cosine of *x*.
asin(x) -- Return the arc sine of *x*.
atan(x) -- Return the arc tangent of *x*
atan2(x, y) -- Return 'atan(y / x)'.
ceil(x) -- Return the ceiling of *x* as a real.
cos(x) -- Return the cosine of *x*
cosh(x) -- Return the hyperbolic cosine of *x*.
exp(x) -- Return 'e**x'
fabs(x) -- Return the absolute value of the real *x*.
floor(x) -- Return the floor of *x* as a real.
fmod(x, y) -- Return 'fmod(x, y)', as defined by the platform C
library. Note that the Python expression 'x % y' may not return
the same result.
fexp(x) -- Return the mantissa and exponent of *x* as the pair '(m, e)'. *m*
is a float and *e* is an integer such that 'x == m * 2**e'. If
*x* is zero, returns '(0.0, 0)', otherwise '0.5 <= abs(m) < 1'.
hypot(x, y) -- Return the Euclidean distance, 'sqrt(x*x + y*y)'.
ldexp(x, y) -- Return 'x * (2**i)'.
log(x) -- Return the natural logarithm of *x*.
log10(x) -- Return the base-10 logarithm of *x*.
modf(x) -- Return the fractional and integer parts of *x*. Both results
carry the sign of *x*. The integer part is returned as a real.
pow(x, y) -- Return *x* to the power of *y*.
sin(x) -- Return the sine of *x*.
sinh(x) -- Return the hyperbolic sine of *x*.
sqrt(x) -- Return the square root of *x*.
tan(x) -- Return the tangent of *x*.
tanh(x) -- Return the hyperbolic tangent of *x*.
Attributes
e -- The mathematical constant *e*.
pi -- The mathematical constant *pi*.

it, you can generate random numbers and select random elements from
sequences. This module is a standard Python module.
Functions
choice(seq) -- Chooses a random element from the non-empty sequence
'seq' and returns it.
randint(a, b) -- Returns a random integer 'N' such that 'a<=N<=b'.
random() -- Returns the next random floating point number in the range
[0.0 ... 1.0).
seed(x, y, z) -- Initializes the random number generator from the
integers 'x', 'y' and 'z'. When the module is first imported, the random
number is initialized using values derived from the current time.
uniform(a, b) -- Returns a random real number 'N' such that 'a<=N<b'.

2.1 documentation.

searching functions. It is a standard Python module.
searching functions. It is a standard Python module.
Functions
Since Zope 2.4 requires Python 2.1, make sure to consult the Python
2.1 documentation.
atof(s) -- Convert a string to a floating point number. The string
must have the standard syntax for a floating point literal in Python,
optionally preceded by a sign ("+" or "-"). Note that this behaves
identical to the built-in function float() when passed a string.
atoi(s [,base]) -- Convert string s to an integer in the given
base. The string must consist of one or more digits, optionally
preceded by a sign ("+" or "-"). The base defaults to 10. If it is 0,
a default base is chosen depending on the leading characters of the
string (after stripping the sign): "0x" or "0X" means 16, "0" means
8, anything else means 10. If base is 16, a leading "0x" or "0X" is
always accepted, though not required.
atol(s, [,base]) --Convert string s to a long integer in the given
base. The string must consist of one or more digits, optionally
preceded by a sign ("+" or "-"). The base argument has the same
meaning as for atoi(). A trailing "l" or "L" is not allowed,
except if the base is 0. Note that when invoked without base or
with base set to 10,
capitalize(word) -- Capitalize the first character of the argument.
capwords(s) -- 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, and removes leading and trailing
whitespace.
find(s, sub [,start [,end]]) -- Return the lowest index in s where
the substring sub is found such that sub is wholly contained in
s[start:end]. Return -1 on failure. Defaults for start and end and
interpretation of negative values is the same as for slices.
rfind(s, sub [,start [,end]]) -- Like find() but find the highest
index.
index(s, sub [,start [,end]]) -- Like find() but raise ValueError
when the substring is not found.
rindex(s, sub [,start [,end]]) -- Like rfind() but raise ValueError
when the substring is not found.
count(s, sub [,start [,end]]) -- Return the number of
(non-overlapping) occurrences of substring sub in string
s[start:end]. Defaults for start and end and interpretation of
negative values are the same as for slices.
lower(s) -- Return a copy of s, but with upper case letters
converted to lower case.
makestrans(from, to) -- Return a translation table suitable for passing
to translate() that will map each character in from into the
character at the same position in to; from and to must have the
same length.
split(s, [,sep [,maxsplit]]) -- Return a list of the words of the
string s. If the optional second argument sep is absent or None, the
words are separated by arbitrary strings of whitespace characters
(space, tab, newline, return, formfeed). If the second argument sep
is present and not None, it specifies a string to be used as the word
separator. The returned list will then have one more item than the
number of non-overlapping occurrences of the separator in the
string. The optional third argument maxsplit defaults to 0. If it is
nonzero, at most maxsplit number of splits occur, and the remainder
of the string is returned as the final element of the list (thus, the
list will have at most maxsplit+1 elements).
join(words [,sep]) -- Concatenate a list or tuple of words
with intervening occurrences of sep. The default value for sep
is a single space character. It is always true that
'string.join(string.split(s, sep), sep)' equals s.
lstrip(string) -- Return a copy of s but without leading whitespace
characters.
rstrip(string) -- Return a copy of s but without trailing whitespace
characters.
strip(string) -- Return a copy of s without leading or trailing
whitespace.
swapcase(s) -- Return a copy of s, but with lower case letters
converted to upper case and vice versa.
translate(s, table [,deletechars]) -- Delete all characters from s
that are in deletechars (if present), and then translate the
characters using table, which must be a 256-character string giving
the translation for each character value, indexed by its ordinal.
upper(s) -- Return a copy of string, but with lower case letters
converted to upper case.
ljust(string, width) -- Left-justifies a string in a field of
given width. Returns a string that is at least width characters
wide, created by padding the string with spaces until the given
width. The string is never truncated.
rjust(string, width) -- Right-justifies a string in a field of
given width. Returns a string that is at least width characters
wide, created by padding the string s with spaces until the
given width. The string is never truncated.
center(string, width) -- Centers a string in a field of given
width. Returns a string that is at least width characters wide,
created by padding the string s with spaces until the given
width. The string is never truncated.
zfill(s, width) -- Pad a numeric string on the left with zero
digits until the given width is reached. Strings starting with a sign
are handled correctly.
replace(s, old, new [,maxsplit]) -- Return a copy of string s with
all occurrences of substring old replaced by new. If the optional
argument maxsplit is given, the first maxsplit occurrences are
replaced.
Attributes
digits -- The string '0123456789'
hexdigits -- The string '0123456789abcdefABCDEF'.

lowercase -- A string containing all the characters that are considered
lowercase letters. On most systems this is the string
'abcdefghijklmnopqrstuvwxyz'.
octdigits -- The string '01234567'.
uppercase -- A string containing all the characters that are considered
uppercase letters. On most systems this is the string
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.
whitespace -- A string containing all characters that are considered
whitespace. On most systems this includes the characters space, tab,
linefeed, return, formfeed, and vertical tab.
