Assignment of an object to a single target is recursively defined as follows. However it is not clear how you derive returns for each security, e. Code compiled by calls to the built-in functions and that occur in a module M containing a future statement will, by default, use the new syntax or semantics associated with the future statement. In this last case the syntax was legal, so the interpreter went on to execute the instruction. Names listed in a statement must not be used in the same code block textually preceding that statement.

However returns is empty list so, whatever the value of s is, there is no element at index s i.

Printing Lists By default, the list type does a repr on all items, and adds brackets and commas as necessary. This is an assignment statement, with a variable, width, on the left. The first form of statement binds the module name in the local namespace to the module object, and then goes on to import the next identifier, if any. The bounds should evaluate to small integers. In the current implementation, the built-in variable is True under normal circumstances, False when optimization is requested command line option. For any given release, the compiler knows which feature names have been defined, and raises a compile-time error if a future statement contains a feature not known to it. At that point width was associated with its original value 10, so width + 5 had the value of 10 + 5 which is 15.

The instance so created by calling the constructor is used as the exception value. For user-defined objects, the method is called with appropriate arguments. The first items of the iterable are assigned, from left to right, to the targets before the starred target. Finally, the sequence object is asked to replace the slice with the items of the assigned sequence. When passes control out of a statement with a clause, that finally clause is executed before really starting the next loop cycle.

The specification for relative imports is contained within.

Please talk about the time when it matters which one you use - your examples don't show when the two will have different effects other than minor speed differences. This can be controlled by optional arguments to — see the documentation of that function for details. If the second object is a tuple, it is used as the argument list for the class constructor; if it is None, an empty argument list is used, and any other object is treated as a single argument to the constructor. For larger structures, you may need a specialized data structure, such as collections. A basic flaw in the late s, estimates showed that because people are all different; similarly for colleges, universities and other areas of tangible full.
