This is why the canonical C main() function usually returns an integer: C minimal_program.c int main(){ return 0; } This example shows a minimal amount of C code necessary for the file to compile with gcc without any warnings. It has a main() function that returns an integer. ...
为此,我们必须通过使用以下if语句构建copy2()调用复制的文件的目标路径,以便在命令行提供目录时连接正确的路径: shutil.copy2(source, dest)ifos.path.isdir(dest): dest_file = os.path.join(dest, src_file_name)else: dest_file = dest 接下来,我们为pywin32库准备时间戳。我们使用os.path.getctime()方...
