变量名英语

不是。complex英语单词，形容词、名词，作形容词的意思是“复杂的、合成的，作名词的意思是“复合体，综合设施”。不是非法变量名，是Python合法的变量名。

命名规则： 1、变量名的命名规则 变量的命名规则要求用“匈牙利法则”。即开头字母用变量的类型，其余部分用变量的英文意思或其英文意思的缩写,尽量避免用中文的拼音,要求单词的第一个字母应大写。 即： 变量名=变量类型+变量的英文意思（或缩写） 对非通用的变量，在定义时加入注释说明，变量定义尽量可能放在函数的开始处。 见下表： bool(BOOL) 用b开头 bIsParent byte(BYTE) 用by开头 byFlag short(int) 用n开头 nStepCount long(LONG) 用l开头 lSum char(CHAR) 用c开头 cCount float(FLOAT) 用f开头 fAvg double(DOUBLE) 用d开头 dDeta void(VOID) 用v开头 vVariant unsigned int（WORD） 用w开头 wCount unsigned long(DWORD) 用dw开头 dwBroad HANDLE（HINSTANCE） 用h开头 hHandle DWORD 用dw开头 dwWord LPCSTR(LPCTSTR) 用str开头 strString 用0结尾的字符串 用sz开头 szFileName

当然是英语啦！英语是编程语言的母语！同时英语的表达能力更强，能够自解释，让人一看就清晰了然。

addr = address app = application arg = argument asm = assemble asyn = asynchronization auth = authorization / authentication avg = average buf = buffer calc = calculate cert = certificate cmd = command cmp = compare col = column coord = coordinates cur = current db = database dec = decrease del = delete dest / dst = destination dev = device dict = dictionary diff = different dir = directory disp = display dlg = dialog doc = document drv = driver env = environment err = error esc = escape ext = extension exec = execute frm = frame func / fn = function grp = group horz = horizontal idx = index img = image inc = increase info = information init = initial/initialize/initialization ins = insert inst = instance intr = interrupt i18n = internationalization lang = language len = length lib = library lst = list max = maximum mem = memory mid = middle min = minimum msg = message mul = multiply num = number obj = object ofs = offset org = origin param = parameter pic = picture pkg = package pos = position prev = previous prg = program proc = process / procedure prop = properties psw = password ptr = pointer pub = public ref = reference reg = register req = request resp = response res = result ret = return rgn = region rsrc = resource scr = screen sec = second seg = segment sel = select src = source std = standard stm = stream str = string sub = subtract sum = summation svr = server sync = synchronization sys = system tmp / temp = temporary tran / trans = translate/transation/transparent txt = text upd = update upg = upgrade util = utility var = variable ver = version vert = vertical wnd = window

不能，对于编程变量名称最好不要用中文的
