下面是一个示例的Smallf*ck解释器的Python代码:
def smallfuck(code, input):
tape = [0] * 256 # 初始化为0的长度为256的列表
tape_ptr = 0 # 磁带指针
code_ptr = 0 # 代码指针
output = "" # 输出字符串
while code_ptr < len(code):
instruction = code[code_ptr]
if instruction == ">":
tape_ptr += 1
elif instruction == "<":
tape_ptr -= 1
elif instruction == "*":
tape[tape_ptr] = 1 - tape[tape_ptr]
elif instruction == "[" and tape[tape_ptr] == 0:
loop_count = 1
while loop_count > 0:
code_ptr += 1
if code[code_ptr] == "[":
loop_count += 1
elif code[code_ptr] == "]":
loop_count -= 1
elif instruction == "]" and tape[tape_ptr] != 0:
loop_count = 1
while loop_count > 0:
code_ptr -= 1
if code[code_ptr] == "]":
loop_count += 1
elif code[code_ptr] == "[":
loop_count -= 1
elif instruction == ".":
output += chr(tape[tape_ptr])
code_ptr += 1
return output
