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 file file.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
