Hello,
I am writing a program that analyzes files of different formats. I
would like to use a function for each format. Obviously, functions can
be mapped to file formats. E.g. like this:
if file.endswith('xyz'):
xyz(file)
elif file.endswith('abc'):
abc(file)
...
Yet, I would prefer to do something of the following kind:
func = file[-3:]
apply_func(func, file)
Can something of this kind be done in Python?
I may have missed a bit of this thread -- so I have to ask: Has anyone
mentioned using getattr yet? It's a way of looking up *any* attribute
using a string to specify the name. Like this for your particular example:
class Functions: # This could be a module instead of a class
def xyz(...):
...
def abc(...):
...
... and so on ...
ext = os.path.splitext(file) # Parses out the extension
fn = getattr(Functions, ext) # Lookup the correct function
fn(...) # and call it
