使用string_at函数将字节流转换为字符串。 # 导入ctypes模块importctypes# 将字节流转换为字符串string=ctypes.string_at(content,len(content)) 1. 2. 3. 4. 5. 对字符串进行操作。 # 截取字符串示例substring=string[:100]# 替换字符串示例replaced_string=string.replace("old","new")# 比较字符串示例if...
>>> string = " python " >>> string.replace('python','java') #将'python'替换成'java' ' java ' >>> string.strip() #去掉了两边的空格(空字符应该都可以,默认的) 'python' >>> string.rstrip() #去掉右边的空字符 ' python' >>> string.lstrip() #去掉左边的空字符 'python ' >>> stri...

于是char*转bytes可以直接用string_at方法,传入指针地址,以及字符串长度即可。 同样的问题,bytes对象需要传给c/c++代码。。。 直观方式同样是创建char数组array,拷贝bytes之后,再用cast强制转换成c_char_p fromctypesimport* p=(c_char *10)()foriinrange(10): ...
但是我们有时候确实需要进行原地修改的时候也可以使用io.StringIO对象或array 模块进行修改 例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>importio>>>s="hello, xiaoY">>>sio=io.StringIO(s)>>>sio<_io.StringIO object at0x02F462B0>>>sio.getvalue()'hello, xiaoY'>>>sio.seek(11)...
