Not too difficult.
If you store your template as a Python string-formatting template, you can just use string-formatting to do your dirty work: import random HOW_MANY = 1000000 template = """{ "some_string": "%(string)s", "some_int": %(int)i } """ wordlist = [ word.rstrip() for word in open('/usr/share/dict/words') ] wordlist[:] = [ # just lowercase all-alpha words word for word in wordlist if word.isalpha() and word.islower() ] for i in xrange(HOW_MANY): fname = "data_%08i.json" % i with open(fname, "w") as f: f.write(template % { "string_value": random.choice(wordlist), "int_value": random.randint(0, 1000), }) -tkc -- https://mail.python.org/mailman/listinfo/python-list
