在Python中,可以通过以下几种方法来提高print函数的打印速度: 使用sys.stdout.write()代替print()函数:print()函数会自动在输出末尾添加换行符,而sys.stdout.write()可以直接输出不带换行符的内容,从而减少输出的开销。 ="hljs">="hljs-keyword">importsys sys.stdout.write(="hljs-string">'Hello,World!')...
If the first expression evaluates to None, then sys.stdout is used as the file for output....
