注意subprocess.call会返回两个值0和2(有时也会返回1),返回0表示目标可达,返回2表示不可达(1也表示不可达)。所以下面的check_ping_result(self)方法用来做判断,如果返回的值是0 (if self.ping_result == 0:),则将它写入reachable_ip.txt文件中reachable_ip.txt(self.f.write(self.ip + "\n")) 执行案例...
然而,如果我们找到匹配的目录,我们会记录目录的路径,并将is_directory属性设置为True: ifdollar_r_filesisNone: dollar_r_dir = os.path.join(recycle_file_path,"$R"+ dollar_i[0][2:]) dollar_r_dirs = tsk_util.query_directory(dollar_r_dir)ifdollar_r_dirsisNone: file_attribs['dollar_r_file...
ndarray.getfield(dtype[, offset]) 返回给定数组的字段作为特定类型。ndarray.setflags([write, align, uic]) 分别设置数组标志WRITEABLE,ALIGNED,(WRITEBACKIFCOPY和UPDATEIFCOPY)。ndarray.fill(value) 使用标量值填充数组。 形状操作 对于重新n整形,调整大小和转置,单个元组参数可以用将被解释为n元组的整数替换。

Given a non-negative integer c, your task is to decide whether there're two integers a and b such that a2 + b2 = c. 坑:需要将类型都设置为long!!! class Solution { // Binary Search public boolean judgeSquareSum(int c) { for (long a = 0; a * a <= c; a++) { if (find(0...
