-Hello friends and welcome to the tutorial on "Writing Python scripts"
-
-{{{ Show the slide containing title }}}
-
-{{{ Show the slide containing the outline slide }}}
-
-In this tutorial, we shall learn
-
- * How write Python scripts
-
-Often we will have to reuse the code that we haave written. We do that by
-writing functions. Functions are bundled into packages and are imported as and
-required in the script.
-
-Let us first write a function that computes the gcd of two numbers and save it
-in a script.
-
-{{{ Open an editor and start typing out the following code }}}
-::
-
- def gcd(a, b):
-
- while b:
- a, b = b, a%b
-
- return a
-
-We shall write an test function in the script that tests the gcd function every
-time the script is run.
-
-{{{ Add to the script }}}
-
-::
-
- if gcd(40, 12) == 4:
- print "Everything OK"
- else:
- print "The GCD function is wrong"
-
-Let us save the file as script.py in /home/fossee/gcd_script.py
-
-We shall run the script by doing
-::
-
- $ python /home/fossee/gcd_script.py
-
-We can see that the script is executed and everything is fine.
-
-What if we want to use the gcd function in some of our later scripts. This
-is also possible since every python file can be used as a module.
-
-But first, we shall understand what happens when you import a module.
-
-Open IPython and type
-::
-
- import sys
- sys.path
-
-This is a list of locations where python searches for a module when it
-encounters an import statement.
-
-hence when we just did =import sys=, python searches for a file named sys.py or
-a folder named sys in all these locations one by one, until it finds one.
-
-We can place our script in any one of these locations and can import it.
-
-The first item in the list is an empty string which means the current working
-directory is also searched.
-
-Alternatively, we can also import the module if we are working in same
-directory where the script exists.
-
-Since we are in /home/fossee, we can simply do
-::
-
- import gcd_script
-
-We can see that the gcd_script is imported. But the test code that we added at
-the end of the file is also executed.
-
-But we want the test code to be executed only when the file is run as a python
-script and not when it is imported.
-
-This is possible by using =__name__= variable.
-
-First we shall look at how to use the idiom and then understand how it works.
-
-Go to the file and add
-::
-
- if __name__ == "__main__":
-
-before the test code and indent the test code.
-
-Let us first run the code.
-::
-
- $ python gcd_script.py
-
-We can see that the test runs successfully.
-
-Now we shall import the file
-::
-
- import gcd_script
-
-We see that now the test code is not executed.
-
-The __name__ variable is local to every module and it is equal to __main__ only
-when the file is run as a script.
-
-hence all the code that goes after __name__ == "__main__" is executed only when
-the file is run as a python script.
