我是一個相對的Python初學者,爲了加強我的技能,我(試圖)編寫Brainfu**
語言的編譯器。一切都很好,除了支架[]
循環。我使用的測試我的代碼的程序是>++[>++<-]>+
,這應該設置小區2至5。當我運行這一點,但是,它這樣做:Python Brainf *** - 在while循環上的錯誤

(該線在迭代格式,然後將名單在這一點上,則該值它的重點,然後字符,它的運行。)
我當前的代碼是
def generateArray(code):
array = []
for i in range(0,20):
array.append(0);
return array
def run(code):
print code
data = generateArray(code)
chars = list(code)
pointer = 0
for i in range(0, len(chars)):
current = chars[i]
if(current == "+"):
data[pointer] += 1
if(current == ">"):
pointer += 1
if(current == "-"):
data[pointer] -= 1
if(current == "<"):
pointer -= 1
if(current == "."):
print str(chr(data[pointer]))
if(current == ","):
given = raw_input()
data[pointer] = ord(given)
if(current == "["):
posOfEnd = chars[i:len(chars)].index("]")
if(data[pointer] == 0):
i += posOfEnd+1
if(current == "]"):
posOfBegin = len(chars) - 1 - chars[::-1].index('[')
i = posOfBegin
print i, data, data[pointer], chars[i]
return data
print run(">++[>++<-]>+")
posOfEnd
試圖找出下一個支架,並posOfBegin
試圖找出預先的位置vious括號是。
看起來像python遍歷範圍(0,len(chars))''就像你告訴它的那樣。在循環中修改'i'不起作用。 – melpomene
