hi,
i am trying to make a pythagorean triples checker (a^2 + b^2 = c^2).
the user enters three sides to a triangle and my code determines if it
is a pythagorean triple (aka right triangle) or not. i have the entire
code pretty much done, except i want to account for variability in
user input, like using commas or just spaces. the user input is
initially a string, but is converted to a list once run through
.split() . I would like to split the user input by commas or spaces,
so:
3 4 5
3,4,5
3, 4, 5
all become: [“3", “4", “5"].
Several solutions have been suggested (of which the re.findall approach
appeals to me the most) but one that hasn't and might be worth
considering is use of str.maketrans() and s.translate().
https://docs.python.org/2/library/string.html#string.maketrans
https://docs.python.org/2/library/string.html#string.translate
From https://docs.python.org/3/whatsnew/3.1.html#other-language-changes
"The string.maketrans() function is deprecated and is replaced by new
static methods, bytes.maketrans() and bytearray.maketrans(). This change
solves the confusion around which types were supported by the string
module. Now, str, bytes, and bytearray each have their own maketrans and
translate methods with intermediate translation tables of the
appropriate type."
