在Python中,关闭文件句柄可以使用close()方法来实现。只需要在文件句柄后面加上.close()即可关闭文件句柄,如下所示:
file = open("file.txt", "r")# do something with the filefile.close()另外,还可以使用with语句来打开文件,这样可以在结束时自动关闭文件句柄,无需手动调用close()方法,示例如下:
with open("file.txt", "r") as file: # do something with the file pass# file is automatically closed after exiting the with block
