This presentation cannot be shared unless the course is completed. The slides can be
shared by the course provider end of the session only.

Gives a brief overview of the Python programming. Describe the major focus of the
presentation and why it is important.
Introduce each of the major topics.
To provide a road map for the audience, you can repeat this Overview slide
throughout the presentation, highlighting the particular topic you will discuss next.

There is no standard definition of "scripting language", but this set of criteria pretty
much captures what most people mean by the term.
Note that Java is interpreted (it requires a JVM) but it is statically (strongly) typed and
requires a compilation step, so it is not a scripting language.

I got tired of cutting and pasting in pictures. This selection is possibly one-third of the
Python books on the market in May of 2003.
One way to judge the acceptance of a language is by how many O'Reilly books cover
it! Note that there are several O'Reilly books on this page, including "Python in a
Nutshell" (a VERY good book), and there are others not shown – "Learning Python" by
Lutz, the "Python Cookbook", etc.

Recursion is not a best practice for automations. Most preferred way is using loops

Try to see y value not having the string in the x.

The approach using string.Template is easy to learn and should be familiar to bash
users. It is suitable for exposing to end-users. This style became available in Python
2.4.
The percent-style will be familiar to many people coming from other programming
languages. Some people find this style to be error-prone because of the trailing "s"
in %(name)s, because the %-operator has the same precedence as multiplication, and
because the behavior of the applied arguments depends on their data type (tuples
and dicts get special handling). This style has been supported in Python since the
beginning.
The curly-bracket style is only supported in Python 2.6 or later. It is the most flexible
style (providing a rich set of control characters and allowing objects to implement
custom formatters).

Because Python doesn't have (and doesn't need) a formal Interface contract, the
Java-style distinction between abstraction and interface doesn't exist. If someone
goes through the effort to define a formal interface, it will also be an abstract class.
The only differences would be in the stated intent in the docstring.
And the difference between abstract and interface is a hairsplitting thing when you
have duck typing.
Java uses interfaces because it doesn't have multiple inheritance.

Shape=type(“Shape”,(object,),{})
def area():
Rect=type(“Rect”,(Shape,),{l=2,b=4}

Greedy means match longest possible string.
Lazy means match shortest possible string.
For example, the greedy h.+l matches 'hell' in 'hello' but the lazy h.+?l matches 'hel'.

>>> s = ‘<a href=“index.html”>HERE</a><font size=“10”>’

164

As you can see, the method split has two optional parameters. If none is given (or is
None) , a string will be separated into substring using whitespaces as delimiters, i.e.
every substring consisting purely of whitespaces is used as a delimiter.

Remember that print >> automatically appends an end-of-line marker
Which is why the program above strips whitespace off the end of the string
before printing it

The whence argument is optional and defaults to os.SEEK_SET or 0 (absolute file
positioning);
other values are os.SEEK_CUR or 1 (seek relative to the current position) and
os.SEEK_END or 2 (seek relative to the file’s end).

The CSV (comma separated value) format is a common format used for spreadsheets
and databases, for importing and exporting of data. Each line or record in the file has
its fields separated by a delimiter, which can be a comma, tab, etc.
