Control Flows From Python

     As Other Languages Python also has control flow Statements. They are as follows:-

if Statement

     It used to check condition according to it control program flow.
Syntax: 
    if condition:
        statement1
        statement2
        ...

if..else Statement

     It is used control flow according to condition, If condition evaluates to True, It will execute if block, else block otherwise.
Syntax: 
    if condition:
        statement1
        statement2
        ...
    else:
        statement1
        statement2
        ...
Example: 
>>> a = 3
>>> b = 9
>>> if b > a:
...     print "B is Max"
... else:
...     print "A is Max"
... 
B is Max

if..elif..else Statement

     Python Doesn't supports switch...case like C or Java, it is replaced with if - elif - else. It first checks if condition if it evaluates true it executes statements enclosed within otherwise it goes to elif, checks condition if it is true it executes statements in it's block otherwise it executes else block statements.
Syntax: 
    if condition:
        statement1
        statement2
        ...
    elif condition:
        statement1
        statement2
    else:
        statement1
        statement2
        ...
Example:
     We slightly modify above program. As follows, 
>>> a = 3
>>> b = 9
>>> b = 7
>>> if a > b and a > c:
...     print "A is Max"
... elif b > c:
...     print "B is Max"
... else:
...     print "C is Max"
... 
B is Max
     That's it. We Will See Next Loops, Keep Following.

Getting Started With Python

     Python is an easy to learn, powerful, general purpose programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.     The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, https://www.python.org/ and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation.     The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). Python is also suitable as an extension ...

Python List

List      List is data structure in python more like array in c or java. But in python list is mutable.      List is initialized in python using list class or just []. list1 = [] list2 = list() Below are some methods of list object list.append(item)      Add an Item to end of the list. list.count(item)      Returns number of time item appears in the list. list.extend(anotherList)      Extend the list by appending all the items from the given list. list.index(item, [start], [end])      Returns the first index of value. If specified optional arguments start or end, the item is searched within start and end. Raises ValueError if item not present. list.insert(index, item)      Insert an item at a given position, the element is inserted before the index. list.pop([index])      Remove an item from the ...

The dir Function

dir()      The built-in dir() lists names from modules. It returns a sorted list of strings.      Let's import regular expression module:- >>> import re >>> dir(re) ['DEBUG', 'DOTALL', 'I', 'IGNORECASE', 'L', 'LOCALE', 'M', 'MULTILINE', 'S', 'Scanner', 'T', 'TEMPLATE', 'U', 'UNICODE', 'VERBOSE', 'X', '_MAXCACHE', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__version__', '_alphanum', '_cache', '_cache_repl', '_compile', '_compile_repl', '_expand', '_pattern_type', '_pickle', '_subx', 'compile', 'copy_reg', 'error', 'escape', 'findall', 'finditer', 'match', 'purge', 'search', 'split', ...
