我正在为有限状态机创建一个python程序,它不面向对象。但是,我的处理阶段是关闭的。它甚至似乎没有通过我创建的三重for循环运行,我通过尝试打印CurrentState进行了检查。任何帮助都将不胜感激。你知道吗
import sys
try:
Sfile = open("states.txt","r")
except IOError:
print "Could not open file", states.txt
os.kill()
States = []
ReadLine = Sfile.readline()
while ReadLine != "":
SN, SS, AS = ReadLine.split(",")
States.append((SN, bool(int(SS)), bool(int(AS))))
ReadLine = Sfile.readline()
print States, "\n"
Sfile.close()
try:
Tfile = open("transistions.txt","r")
except IOError:
print "Could not open file", transitions.txt
os.kill()
Transitions = []
ReadLine = Tfile.readline()
while ReadLine != "":
ReadLine = ReadLine.rstrip()
CS, IN, NS = ReadLine.split(",")
Transitions.append((CS, IN, NS))
ReadLine = Tfile.readline()
print Transitions
Tfile.close()
try:
Strfile = open("strings2.txt","r")
except IOError:
print "Could not open file", strings2.txt
os.kill()
Strings = []
ReadLine = Strfile.readline()
while ReadLine != "":
Readline = ReadLine.rstrip()
Strings.append(Readline)
ReadLine = Strfile.readline()
print Strings, '\n'
Strfile.close()
CurrentState = ''
Start = ''
RejectState= ''
AcceptState= ''
for S in Strings:
if S != '':
for C in S:
for (CS, IN, NS) in Transitions:
if CS == CurrentState and IN == C:
CurrentState =NS
break
for (SN, SS, AS) in States:
if SN == CurrentState and SS ==C:
CurrentState = NS
if NS == AS:
NS = AcceptState
print "String", AcceptState, "is accepted"
break
else:
NS = RejectState
print "String", RejectState, "is rejected"
break
以下是我的不同文本文件: 字符串2.txt
01010
1001
010
你知道吗转换.txt你知道吗
Start,0,State1
State1,1,State2
State2,0,State3
你知道吗状态.txt你知道吗
State1,1,0
State2,0,1
State3,1,0
我复制了您的代码和数据,并且能够使用python2.7使此代码(稍微修改了您的代码)正常工作:
这是我得到的结果:
