我就廢話不多說了，還是直接看代碼吧！

# 利用python在內(nèi)存中讀寫str和二進制數(shù)據(jù)from io import StringIOfrom io import BytesIO f = StringIO()print(f.write(’hello ’)) # 6print(f.write(’world!’)) # 6print(f.getvalue()) # hello world! f = BytesIO()print(f.write(’中文’.encode(’utf-8’))) # 6print(f.getvalue()) # b’xe4xb8xadxe6x96x87’

補充知識：python二進制轉(zhuǎn)到float

看代碼吧！

以上這篇python實現(xiàn)在內(nèi)存中讀寫str和二進制數(shù)據(jù)代碼就是小編分享給大家的全部內(nèi)容了，希望能給大家一個參考，也希望大家多多支持好吧啦網(wǎng)。
