i wrote code meant try approach target string selecting randomly list of chars, have problem not quite understand.
import random class monkiesgo: __chars = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'] def __init__(self, targetstring): __targetstring = targetstring.lower() __targetlist = list(targetstring) __attemptlist = [] __unmatchedindexes = [ x x in range(0, (len(targetstring)-1)) ] def attempttosolve(self): if len(__unmatchedindexes) == 0: __attemptstring = ''.join(__attemptlist) return __attemptstring, __targetstring else: index in __unmatchedindexes: __attemptlist[index] = randomchar() def updatesolutionprogress(self): indexcheck in __unmatchedindexes: if __targetlist[index] == __attemptlist[index]: __indextoclear = __unmatchedindexes.index(index) del __unmatchedindexes[indexttoclear] def __randomchar(self): return __chars[ random.randint(0,26) ] when import python shell in terminal, make object follows:
from monkies import monkiesgo mk = monkiesgo("hello") mk.attempttosolve() i error:
traceback (most recent call last): file "", line 1, in
file "path/to/the/file/monkies.py", line 15, in attempttosolve if len(__unmatched 0: nameerror: name '_monkiesgo__unmatched' not defined
what causing this, , why there underscore before monkiesgo?
thanks in advance.
updated to:
import random class monkiesgo: def __init__(self, targetstring): self.targetstring = targetstring.lower() self.targetlist = list(targetstring) self.attemptlist = [] self.unmatchedindexes = [ x x in range(0, (len(targetstring)-1)) ] self.chars = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'] def attempttosolve(self): if len(self.unmatchedindexes) == 0: self.attemptstring = ''.join(self.attemptlist) return self.attemptstring, self.targetstring else: index in self.unmatchedindexes: self.attemptlist[index] = randomchar() def updatesolutionprogress(self): indexcheck in self.unmatchedindexes: if self.targetlist[index] == self.attemptlist[index]: indextoclear = self.unmatchedindexes.index(index) del self.unmatchedindexes[indexttoclear] def randomchar(self): return self.chars[ random.randint(0,26) ] now name error regarding randomchar..?
you not creating instance variables. in function __init__, variables such __targetstring local , defined within function. when call function attempttosolve, variable __unmatchedindices local , therefore undefined. double underscore not automatically make instance variable; perhaps that's confusion.
instead of __targetstring = whatever, should use self.__targetstring = whatever, or better yet drop underscores , use self.targetstring. creates member variable. access in member functions using same self.targetstring syntax. check out tutorial comes python.
