windows7环境下,执行代码报ValueError: embedded null byte时,在原代码前面加一行代码:locale.setlocale(locale.LC_ALL,'en')即可解决 即: locale.setlocale(locale.LC_ALL,'en') locale.setlocale(locale.LC_CTYPE,'chinese') ws["C3"]=time.strftime('%Y年%m月%d日 %H时%M分%S秒',time.localtime())...

This variant on "s" stores into two C variables, the first one a pointer to a character string, the second one its length. In this case the Python string may contain embedded null bytes. Unicode objects pass back a pointer to the default encoded string version of the object if such a ...

a pointer to an existing string is stored into the character pointer variable whose address you pass. The C string is null-terminated. The Python string must not contain embedded null bytes; if it does, aTypeErrorexception is raised. Unicode objects are converted to C strings using the default...

Python是解释型语言,没有严格意义上的编译和汇编过程。但是一般可以认为编写好的python源文件,由python解释器翻译成以.pyc为结尾的字节码文件。pyc文件是二进制文件,可以由python虚拟机直接运行。 Python在执行import语句时,将会到已设定的path中寻找对应的模块。并且把对应的模块编译成相应的PyCodeObject中间结果,然后创建...
