fileinput 内置了两个勾子函数: fileinput.hook_encoded(encoding,errors=None)使用gzip和bz2模块透明地打开 gzip 和 bzip2 压缩的文件 fileinput.hook_compressed(filename,mode)使用给定的 encoding 和 errors 来读取文件。 从标准输入中读取 若input()不传任何参数时,fileinput默认会以stdin作为输入源。 运行stdin...
The above code will read file data into a buffer of 1024 bytes. Then we are printing it to the console. When the whole file is read, the data will become empty and thebreak statementwill terminate the while loop. This method is also useful in reading a binary file such as images, PDF...
