I would like to pass the contents of a dictionary from one program to another through a file. So, what is the elegant way to pass a dictionary by file?
The elegant way may be not to use a file. A Python dictionary usually converts easily to JSON format which can be sent directly between processes over http. If you control the receiving program. Alternatively, you could save the JSON into a file and pass that between processes. If the receiving program knows about JSON. Or you could just use the Python pickle module to save the dictionary. If the receiving program is in Python. Or you could write the dictionary out to a CSV file using the csv module. If the other program is not under your control and needs to use standard format files. (eg Excel)
more about Python. In C++, I was very happy using structs and classes with serialization. Is the Python solution somewhat similar to C++?
You can do it manually but in Python there is usually a better way. One of the options above should work for you, it depends on how much control you have over the receiving program code. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
