How can I remove the single quotes from a string and use it for division in Python?
a='/'
b=6
c=3

bac

a = "/"
b = "6"
c = "3"
print eval(b + a + c)

import operator

a = operator.div
b = 6
c = 3

print a(b, c)

ops = {
    "/": operator.div,
    "*": operator.mul,
    # et cetera
}

a = ops["/"]

>>> a='/'
>>> b=6
>>> c=3
>>> bac = ''.join(str(x) for x in (b, a, c))
>>> bac
'6/3'

>>> eval(bac)
2
