One version of the code does it using os.stat()[stat.ST_SIZE]: size1,size2 = 1,0 while size1 != size2: size1 = os.stat(file_name)[stat.ST_SIZE] time.sleep(300) size2 = os.stat(file_name)[stat.ST_SIZE] Another version does it with os.path.getsize(): size...
可以使用os模块的stat方法来获取文件的大小。 以下是获取文件大小的示例: importos size=os.stat('file.txt').st_size print(size) 2. 判断文件是否存在 可以使用os模块的path方法来判断文件是否存在。 以下是判断文件是否存在的示例: importos exists=os.path.exists('file.txt') print(exists) 3. 删除文件...
size(file_name) → integer Show source 返回file_name的大小。 file_name可以是IO对象。 代码语言:javascript 复制 static VALUE rb_file_s_size(VALUE klass, VALUE fname) { struct stat st; if (rb_stat(fname, &st) < 0) { int e = errno; FilePathValue(fname); rb_syserr_fail_path(e...
