How to Resolve the TypeError: 'str' does not support the buffer interface when using gzip.open in Python?

TypeError: 'str' 不支持缓冲区接口

问题:

何时尝试使用Python的gzip.open函数压缩字符串,错误是抛出:

TypeError: 'str' does not support the buffer interface

如何解决这个问题?

答案:

Python 3 升级: 在 Python 中3、字符串是Unicode对象,没有缓冲接口。要解决此问题,必须在写入输出文件之前将字符串转换为字节:

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(plaintext.encode())

缓冲区兼容性: 为了确保与旧版本 Python 的兼容性,请显式指定编码:

outfile.write(plaintext.encode('utf-8'))
