Question

我尝试将一些time.sleep(.1)添加到我正在使用的循环中，但它似乎阻碍了执行（在我的CTRL+C上点击IDLE之后我得到time.sleep(.1)... KeyboardInterrupt这证实了我的想法）

我尝试使用代码，发现在该行之后添加print()可以防止暂停，但我仍然不明白为什么它首先发生...

在没有sleep的情况下运行此操作我没有任何问题，所以我认为没有其他问题可以导致这种情况。对我有用的另一件事是使用sleep(0)。我输入的任何正值都会再次阻止执行。

可疑行在循环结束时。

这是整个代码：

import time 

def main():
    with open(r'txt.bin') as f:

        code = f.read()
        data = [0 for i in range(22)]
        data_p = 0
        code_p = 0
        reverse_code = code[::-1]
        l = len(code)
        flag = False

        while code[code_p] != '.':

            if data_p == 1:
                #print('char read {0}     {1}:  {2}'.format(c, data_p,data[1]))
                pass

            c = code[code_p]
            if c == '+':
                data[data_p] += 1
                data[data_p] %= 256
            elif c == '-':
                data[data_p] -= 1
                if data[data_p] < 0:
                    data[data_p] = 255
            elif c == '>':
                data_p += 1
            elif c == '<':
                data_p -= 1
            elif c == ',':
                old = int(data[data_p])
                data[data_p] = int(input('enter value at {0} (current value is {1}):    '.format(data_p, data[data_p])))
                print('replaced {0} with {1} at {2}'.format(old, data[data_p],data_p))
                flag = True
            elif c == '[':
                if data[data_p] is 0:
                    old = int(code_p)
                    code_p = code.find(']', code_p)
                    print('started at loc {0} with val {1}\nnow at loc {2} with val {3}'.format(old, code[old], code_p, code[code_p]))
            elif c == ']':
                if data[data_p] is not 0:
                    reverse_code_p = l-1-code_p
                    old = int(code_p)
                    code_p = l-1-reverse_code.find('[', reverse_code_p)
                    print('started at loc {0} with val {1}\nnow at loc {2} with val {3}'.format(old, code[old], code_p, code[code_p]))

            if flag:
                time.sleep(1)


            code_p += 1

        print(data[data_p])
main()

使用time.sleep（X）暂停执行
