    Why is not all memory freed when Python exits?

    Objects referenced from the global namespaces of Python modules are not always de-allocated when Python exits. This may happen if there are circular references. There are also certain bits of memory that are allocated by the C library that are impossible to free (e.g. a tool like the one Purify will complain about these). Python is, however, aggressive about cleaning up memory on exit and does try to destroy every single object.

    If you want to force Python to delete certain things on de-allocation, you can use the at exit module to register one or more exit functions to handle those deletions.

    What are the disadvantages of the Python programming language?

    One of the disadvantages of the Python programming language is it is not suited for fast and memory intensive tasks.

    Try:

    Import module1

    Except:

    Pass

    What is the optional statement used in a try except statement in Python?

    There are two optional clauses used in try except statements:

    1. Else clause: It is useful for code that must be executed when the try block does not create any exception

    2. Finally clause: It is useful for code that must be executed irrespective of whether an exception is generated or not.

    Describe how to generate random numbers in Python.

    Thee standard module random implements a random number generator.

    There are also many other in this module, such as:

    uniform(a, b) returns a floating point number in the range [a, b].
    randint(a, b)returns a random integer number in the range [a, b].
    random()returns a floating point number in the range [0, 1].

    Following code snippet show usage of all the three functions of module random:
    Note: output of this code will be different evertime it is executed.

    import random
    i = random.randint(1,99)# i randomly initialized by integer between range 1 & 99
    j= random.uniform(1,999)# j randomly initialized by float between range 1 & 999
    k= random.random()# k randomly initialized by float between range 0 & 1
    print("i :" ,i)
    print("j :" ,j)
    print("k :" ,k)
    __________
    Output -
    ('i :', 64)
    ('j :', 701.85008797642115)
    ('k :', 0.18173593240301023)

    Output-
    ('i :', 83)
    ('j :', 56.817584548210945)
    ('k :', 0.9946957743038618)

    Describe how to send mail from a Python script.

    The smtplib module defines an SMTP client session object that can be used to send mail to any Internet machine.

    A sample email is demonstrated below.

    import smtplib
    SERVER = smtplib.SMTP(‘smtp.server.domain’)
    FROM = sender@mail.com
    TO = ["user@mail.com"] # must be a list
    SUBJECT = "Hello!"
    TEXT = "This message was sent with Python's smtplib."
    # Main message
    message = """
    From: Sarah Naaz < sender@mail.com >
    To: CarreerRide user@mail.com
    Subject: SMTP email msg
    This is a test email. Acknowledge the email by responding.
    """ % (FROM, ", ".join(TO), SUBJECT, TEXT)
    server = smtplib.SMTP(SERVER)
    server.sendmail(FROM, TO, message)
    server.quit()

    Explain how to overload constructors (or methods) in Python.

    _init__ () is a first method defined in a class. when an instance of a class is created, python calls __init__() to initialize the attribute of the object.

    Following example demonstrate further:

    class Employee:

    def __init__(self, name, empCode,pay):
    self.name=name
    self.empCode=empCode
    self.pay=pay

    e1 = Employee("Sarah",99,30000.00)

    e2 = Employee("Asrar",100,60000.00)
    print("Employee Details:")

    print(" Name:",e1.name,"Code:", e1.empCode,"Pay:", e1.pay)
    print(" Name:",e2.name,"Code:", e2.empCode,"Pay:", e2.pay)
    ---------------------------------------------------------------
    Output

    Employee Details:
    (' Name:', 'Sarah', 'Code:', 99, 'Pay:', 30000.0)
    (' Name:', 'Asrar', 'Code:', 100, 'Pay:', 60000.0)

    How do you make an array in Python?

    The array module contains methods for creating arrays of fixed types with homogeneous data types. Arrays are slower then list. Array of characters, integers, floating point numbers can be created using array module. array(typecode[, intializer]) Returns a new array whose items are constrained by typecode, and initialized from the optional initialized value. Where the typecode can be for instance ‘c’ for character value, ‘d’ for double, ‘f’ for float.

    38. Explain how to create a multidimensional list.

    There are two ways in which Multidimensional list can be created:

    By direct initializing the list as shown below to create multidimlist below

    >>>multidimlist = [ [227, 122, 223],[222, 321, 192],[21, 122, 444]]
    >>>print multidimlist[0]
    >>>print multidimlist[1][2]
    __________________________
    Output
    [227, 122, 223]
    192

    The second approach is to create a list of the desired length first and then fill in each element with a newly created lists demonstrated below :

    >>>list=[0]*3
    >>>for i in range(3):
    >>> list[i]=[0]*2
    >>>for i in range (3):
    >>> for j in range(2):
    >>> list[i][j] = i+j
    >>>print list
    __________________________
    Output
    [[0, 1], [1, 2], [2, 3]]

    What is a negative index in python?

    Python arrays & list items can be accessed with positive or negative numbers (also known as index). For instance our array/list is of size n, then for positive index 0 is the first index, 1 second, last index will be n-1. For negative index, -n is the first index, -(n-1) second, last negative index will be – 1. A negative index accesses elements from the end of the list counting backwards.

    An example to show negative index in python.

    >>> import array
    >>> a= [1, 2, 3]
    >>> print a[-3]
    1
    >>> print a[-2]
    2
    >>> print a[-1]
    3

    How do I convert a string to a number?

    Python contains several built-in functions to convert values from one data type to another data type.

    The int function takes string and coverts it to an integer.
    s = "1234" # s is string
    i = int(s) # string converted to int
    print i+2
    ------------------------
    1236
    The float function converts strings into float number.
    s = "1234.22" # s is string
    i = float(s) # string converted to float
    print i
    -------------------------
    1234.22
