|
help(abs)
|
|
Help on built-in function abs in module builtins:
|
|
|
|
abs(x, /)
|
|
Return the absolute value of the argument.
|
|
|
|
help(len)
|
|
Help on built-in function len in module builtins:
|
|
|
|
len(obj, /)
|
|
Return the number of items in a container.
|
|
|
|
help(max)
|
|
Help on built-in function max in module builtins:
|
|
|
|
max(...)
|
|
max(iterable, *[, default=obj, key=func]) -> value
|
|
max(arg1, arg2, *args, *[, key=func]) -> value
|
|
|
|
With a single iterable argument, return its biggest item. The
|
|
default keyword-only argument specifies an object to return if
|
|
the provided iterable is empty.
|
|
With two or more positional arguments, return the largest argument.
|
|
|
|
help(min)
|
|
Help on built-in function min in module builtins:
|
|
|
|
min(...)
|
|
min(iterable, *[, default=obj, key=func]) -> value
|
|
min(arg1, arg2, *args, *[, key=func]) -> value
|
|
|
|
With a single iterable argument, return its smallest item. The
|
|
default keyword-only argument specifies an object to return if
|
|
the provided iterable is empty.
|
|
With two or more positional arguments, return the smallest argument.
|
|
|
|
help(pow)
|
|
Help on built-in function pow in module builtins:
|
|
|
|
pow(base, exp, mod=None)
|
|
Equivalent to base**exp with 2 arguments or base**exp % mod with 3 arguments
|
|
|
|
Some types, such as ints, are able to use a more efficient algorithm when
|
|
invoked using the three argument form.
|
|
|
|
help(round)
|
|
Help on built-in function round in module builtins:
|
|
|
|
round(number, ndigits=None)
|
|
Round a number to a given precision in decimal digits.
|
|
|
|
The return value is an integer if ndigits is omitted or None. Otherwise
|
|
the return value has the same type as the number. ndigits may be negative.
|
|
|
|
help(sorted)
|
|
Help on built-in function sorted in module builtins:
|
|
|
|
sorted(iterable, /, *, key=None, reverse=False)
|
|
Return a new list containing all items from the iterable in ascending order.
|
|
|
|
A custom key function can be supplied to customize the sort order, and the
|
|
reverse flag can be set to request the result in descending order.
|
|
|
|
help(sum)
|
|
Help on built-in function sum in module builtins:
|
|
|
|
sum(iterable, /, start=0)
|
|
Return the sum of a 'start' value (default: 0) plus an iterable of numbers
|
|
|
|
When the iterable is empty, return the start value.
|
|
This function is intended specifically for use with numeric values and may
|
|
reject non-numeric types.
|
|
|
|
help(zip)
|
|
Help on class zip in module builtins:
|
|
|
|
class zip(object)
|
|
| zip(*iterables, strict=False)
|
|
|
|
|
| The zip object yields n-length tuples, where n is the number of iterables
|
|
| passed as positional arguments to zip(). The i-th element in every tuple
|
|
| comes from the i-th iterable argument to zip(). This continues until the
|
|
| shortest argument is exhausted.
|
|
|
|
|
| If strict is true and one of the arguments is exhausted before the others,
|
|
| raise a ValueError.
|
|
|
|
|
| >>> list(zip('abcdefg', range(3), range(4)))
|
|
| [('a', 0, 0), ('b', 1, 1), ('c', 2, 2)]
