Are repeat counts supported Python's str.format() in some fashion?
In Fortran my format strings can have repeat counts.
<pseudocode>
write(*, fmt="3F8.3") [1, 2, 3]
1.000 2.000 3.000
</pseudocode>
I don't think printf-style format codes, which is what'd I'd
previously used in Python, allow for repeat counts.
As a more concrete example, say I have several sets of letters in a
list of strings
letters = ["aeiou", "hnopty", "egs", "amsp"]
and I wanted to build a regular expression string out of them like
re_str <==> "[aeiou][hnopty][egs][amsp]"
Right now, the best I've got that doesn't require an explicit string
like "[{1}][{2}][{3}][{4}]" is
re_str = "".join(map(lambda x: "[{0}]".format(x), letters))
Is there a better way?
The shortest I can come up with is:
"[" + "][".join(letters) + "]"
