get date and save it as a file name python
date, python, save
Solution
Your filename `05/12/2013.png` contains slashes (`/`) and these are likely pathname separator characters on your OS. In other words, the filename you are trying to write to is `2013.png` in the directory `12`, under the directory `05`. If that's not what you want, then consider changing your filename format to something like `time.strftime("%Y-%m-%d")`, or anything else without slashes.
Problem
I have some graph that I do in python. In the end I save the plot to a png file. Here is the code: ``` plt.scatter(LuxCoordinates, finalPix, linewidths=1) plt.sca plt.grid(axis) plt.xlabel('Ambient', color='r'); plt.ylabel('Depth Grows', color='r'); # grayscale color plt.title(PngName, color='b'); savefig(PngName+'.png'); #PngName is the name of the file that the user gives in argv ``` This work good and it save me a file, name PngName.png (Where PngName is what the user decided) Now I want to add to that name the current date. I had try to do this: ``` date = time.strftime("%d/%m/%Y") plt.scatter(LuxCoordinates, finalPix, linewidths=1) plt.sca plt.grid(axis) plt.xlabel('Ambient', color='r'); plt.ylabel('Depth Grows', color='r'); # grayscale color plt.title(PngName, color='b'); savefig(PngName+'_'+date+'.png') ``` But it's not working, I get this error message: filename_or_obj = open(filename_or_obj, 'wb') IOError: [Errno 2] No such file or directory: '05/12/2013.png' You can see that the date variable get the date. (also when I'm printing it to screen I see the date) What is the problem and how can I solve it? Thanks!
