help(abs)
|

Help on built-in function abs in module builtins:
|
||||
|
||||
abs(x, /)
|
||||
Return the absolute value of the argument.

|
||||
Help on built-in function abs in module builtins:
|
||||
|
||||
abs(x, /)
|
||||
Return the absolute value of the argument.
|
||||
|
||||
Help on built-in function len in module builtins:
|
||||
|
||||
len(obj, /)
|
||||
Return the number of items in a container.
|
||||
|
||||
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 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 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 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 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 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 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)]

|
||||
|
|
||||

|
||||
| Set state information for unpickling.

## 8.2. Кортеж
|
||||
Работа с кортежами - их нельзя изменять, но можно переопределять, таким образом внося изменения.
|
||||
```py

||||

kort1= kort1+(1,2)
|

|
||||
## 8.3. Словарь
|
||||
Работа со словарями. Ключи - неизменяемы.
|
||||

|
||||
dic1={'Saratov':145, 'Orel':56, 'Vologda':45}
|

||||
dic5
|
||||
{'A': 16, 'B': -3, 'C': 9, 'Stroka': 'Меня зовут: \n Соловьёва Е. Д.'}
|
||||
```
|
||||
|
||||
Свой словарь состоит из 5 элементов, потому что мы "сшили" два контейнера, длина определилась по минимальному кол-ву.
|
||||
```py
|
||||
testlist = ['pink','yellow','black','green','red']
|
||||
testkort = ('P','Y','B','G','R','T','Q')
|
||||
dictest=dict(zip(testkort,testlist))

||||
