def isnub( s ): # Determine whether it is a number try: float( s ) #if it is a bumber return True return True except: return False #if it's not a number return False def valid_input1( s1 ): try: _a, _b = s1.split

思路是所有原始数制转换成十进制，然后从十进制转换成目标进制： def fun_any_to_d(n, b): # any to decimal(n : number system, b : operand) a = str(b) list = [] for i in a: list.append(hex_switch.get(i, "False")) for x in list: if x not in range(n) :

#自带操作 abs(number) #绝对值 pow(a, b) #幂 round(number) # 四舍五入Rounds the number to the nearest integer. round(number, ndigits) # 四舍五入保留n位小数 min(arg1, arg2, ... argN) # 找最小值 max(arg1, arg2, ... argN) # 找最大值 import math math.floor(float) # retu
