You can also do this (if tuples are okay in your case):
a = 1,
The comma turns 'a' into a tuple (1,) which is both iterable and has a
length of 1.
I have run into this issue before with a function that took a list of
filenames (strings), and needed to iterate over the list to operate on
the input files. For the case when the input would be a single file, I
needed to turn the input string into an iterable such that the 'for'
loop would not iterate on the filename characters (a rather
undesirable gotcha, you understand :-) ). So I solved my problem like
this:
def loadfiles(filelist):
if not isinstance(filelist, list):
filelist = filelist,
for filename in filelist:
f = open(filename,'r')
#do interesting stuff with file, etc...
..and it's been working very well.
