Hello, I have dictionary {1:"astring", 2:"anotherstring", etc}
I now want to print:
"Press 1 for astring"
"Press 2 for anotherstring" etc
I could do it like this:
dict = {1:'astring', 2:'anotherstring'}
for key in dict.keys():
print 'Press %i for %s' % (key, dict[key])
Press 1 for astring
Press 2 for anotherstring
Remember that a dict is inherently unordered, and if you get it
ordered, you're just lucky :) Also, it's bad style to mask the
builtin "dict" with your own.
but can I use a join instead?
If you want to lean on this ordered assumption, you can simply do
d = {1:"astring", 2:"another string"}
s = '\n'.join(
"Press %i for %s" % pair
for pair in d.iteritems()
)
and you'd have the resulting value in "s".
But remember that if the order appears broken, you get to keep
both parts :) Better to do something like
s = '\n'.join(
"Press %i for %s" % pair
for pair in sorted(d.items())
)
