TypeError: 'str' does not support the buffer interface

原文：

plaintext = input("Please enter the text you want to compress")

filename = input("Please enter the desired filename")with gzip.open(filename + ".gz", "wb") as outfile:    outfile.write(bytes(plaintext, 'UTF-8'))

修改后：

plaintext = 'Polish text: ????ńó????????ó???'filename = 'foo.gz'with gzip.open(filename, 'wb') as outfile:    outfile.write(bytes(plaintext, 'UTF-8'))with gzip.open(filename, 'r') as infile:    outfile_content = infile.read().decode('UTF-8')print(outfile_content)

有python的语法问题需要在read后面加上decode('UTF-8'),写数据的时候需要转换一下bytes(plaintext, 'UTF-8')
