I use a function isListLike in cases such as this one:
# def isListLike(L): # """Return True if L is list-like, False otherwise.""" # try: # L + [] # return True # except: # return False
Then you can use a standard if-else construct:
# if isListLike(myvar): # <do something> # else: # <do something else>
What kind of situations do you use this for? I almost never have to do this kind of typechecking. If it's supposed to be a list, I just use it as a list...
