The following C code FILE * f; int i; char filename[100]; for (i=0; i<10; i++) { sprintf(filename, "foo%d.dat", i); FILE * f = fopen(filename, "w"); /* write stuff to file */ ... fclose(f); } translates into this piece of Python: for i in range(10): filename = "foo%d.dat" % i with open(filename, "w") as f: # write stuff to file ... ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] HELP: Creating animation from multiple plots
You were opening the file for reading, rather than writing. It therefore was expecting to find a file.

Putting "w" instead of "r+" probably solves the problem. The error is not showing now.

Re: [Tutor] HELP: Creating animation from multiple plots
for t in range(0,200): fname = 'file_' + str(t) So it will assign fname values file_0, file_1 so on. Dropping the quotes is giving me IOError: [Errno 2] No such file or directory: 'file_0' Indeed the file is not present. In C we write,if we have to record data in a file FILE *fp fp = fopen("file.dat","w") Here I want to write different data sets in files having different name i.e I want to create the files with the data sets.

Thanks a lot for your prompt reply. 1. Yes. This is exactly what I wanted. Creating a bunch of data sets and then writing script to plot them using gnuplot, but if something can produce directly 'plots' it will certainly be helpful. 2. Yes. By stitching them up I meant an animation.Sorry for the ambiguity. Exactly how we can do it Octave.

It certainly is. Are you talking about the file names being file_1001.txt, file_1002.txt and so on? If yes, let's say your parameter values are stored in param. Then something like this would do the trick: param_values = [1000,1001, 1005, 2001] for param in param_values: fname = 'file_' + str(param) # write to file fname # # Sorry if its different from what you are looking for.

Dear All, I am a newbie to Python but have a fair know how of other languages i.e C etc. I want to run an astrophysical simulation in Python. All I have to do it to generate a set of 'plots' depending on a varying parameter and then stitch them up. 1) Is it possible to automatically generate different data files( say in the orders of 1000) with different names depending on a parameter? 2) Is it possible to plot the data sets right from Python itself and save the plots in different jpeg files to stitched upon later on. Awaiting your reply. Thank you in advance.
