I have some old Common Lisp functions I'd like to rewrite in Python
(I'm still new to Python), and one thing I miss is not having to
declare local variables.
For example, I have this Lisp function:
(defun random-char ()
"Generate a random char from one of [0-9][a-z][A-Z]"
(if (< 50 (random 100))
(code-char (+ (random 10) 48)) ; ascii 48 = 0
(code-char (+ (random 26) (if (< 50 (random 100)) 65 97))))) ;
ascii 65 = A, 97 = a
My Python version looks like this:
def random_char ():
'''Generate a random char from one of [0-9][a-z][A-Z]'''
if random.randrange(0, 100) > 50:
return chr( random.randrange(0, 10) + 48 ) # ascii 48 = 0
else:
offset = 65 # ascii 65 = A
if random.randrange(0, 100) > 50:
offset = 97 # ascii 97 = a
return chr( random.randrange(0, 26) + offset )
Logically, it's equivalent of the Lisp version.
But is there any way to avoid using the local variable (offset) in the
Python version?
