Giving the input file name from the prompt

psbasha

HI,

I have a Samplescript.When I run this Script,it should pop up message saying that whether to run Batch or Interactive

I/P:
SampleScript.py or SampleScript.pyc

>>> SampleScript.py --> Run the script from the prompt
>>> 'Message-Do you want to run as Interactive' --> Program will prompt the message
>>> Yes ---> ( user will type 'Yes' or 'No')
>>> SampleData.txt ---> ( Text file is given as a input)
Application start running

(or )

>>> No
Graphical user interface is pop up
User will input the data
Application start running

Could anybody hlep me in providing the sample code for this

Thanks
PSB

How to get the inputs from the prompt?

Like filename or any flags

I don't think that there is a built-in way to "pop up" the standard python shell. Many good toolkits (like wxPython) have shell re-direction in a window that can be controled by the app. In either case:

Expand|Select|Wrap|Line Numbers

usersChoice = raw_input("Please enter your choice: ")

prints a prompt and waits for charaters from the user followed be the return key. At which point it returns a string.

So we cannot type from the command line argumnets as mentioned below

Say

C:> SampleScript.py
C:> Yes
c:> SampleInput.txt

Similarly in UNIX

/usr/test/> SampleScript.py
/usr/test/> Yes
/usr/test/>SampleInput.txt

Oh, but you can.

Expand|Select|Wrap|Line Numbers

 print "Starting application"

usersChoice = ""

while usersChoice.lower() not in ("yes", "no"):

    usersChoice = raw_input("Is your choice 'yes' or 'no'?")
 
print usersChoice

D:\My Documents\Python\TheScripts examples>test21.py
Starting application
Is your choice 'yes' or 'no'?help
Is your choice 'yes' or 'no'?no
no
D:\My Documents\Python\TheScripts examples>

Expand|Select|Wrap|Line Numbers

print "Starting application"

usersChoice = ""

while usersChoice.lower() not in ("yes", "no"):

usersChoice = raw_input("Is your choice 'yes' or 'no'?")

print usersChoice

D:\My Documents\Python\TheScripts examples>test21.py
Starting application
Is your choice 'yes' or 'no'?help
Is your choice 'yes' or 'no'?no

Or better, still:

Expand|Select|Wrap|Line Numbers

 print "Starting application"

usersChoice = ""

while usersChoice not in ("y", "n"):

    usersChoice = raw_input("Is your choice 'yes' or 'no'? ")[0:1].lower() # slice prevents index errors

    print repr(usersChoice)

if usersChoice == 'y':

    print "The reply was affirmative"

D:\My Documents\Python\TheScripts examples>test21.py
Starting application
Is your choice 'yes' or 'no'? Yelp
'y'
The reply was affirmative
D:\My Documents\Python\TheScripts examples>

I hope this will work in UNIX & Windows OS without Tkinter module installed

I hope this will work in UNIX & Windows OS without Tkinter module installed

Of course it will; it's pure python. Notice that there are no import statements.

I am looking for the input file to be taken from the cmd line as shown below

Sample.py
----------------
After creating a 'Exe' of an application.I will run the application thru command prompt.The exe has to take the input data from the command prompt (i.e sample.txt)

C:\> Sample.exe sample.txt

And the application will start processing

(or )

From 'pyc'

C:\> Sample.pyc sample.txt

(or)

C:\> Sample.py sample.txt

This can be do able in shell scripting

Has anybody tried on this in Python.So that I would like to know ,how it can be implemented in Python.

Thanks

print "starting module"

And the command line and output:

Of course, for this to work with .exe the program will need to be in the PATH environment variable (just like python is in the PATH).

I guess that you got in so deep with all that Tkinter stuff, you missed a lot of the basics.

Amazing!!!.

Without the application in the PATH ,it is working fine for me.I dont know,How it is working?.

I will try to investigate on this.

Perhaps the command-line points to the directory of the .exe. That would do it. But that is not likely to be the case in "the real world".

The batch and interactive execution of the application on DOS prompt is not working consistantly.Some times it work and other times it will not work.It looks like the program thread is stopping to execute the application to run next time.

How to kill the application thread which is running already or How to identify the application is running or not?.
