python 两个队列进行对比 list01 = [1,2,3,4] list02 = [1,3,5] for i01 in list01: is_in_02 = False for i02 in list02: if i01 == i02: is_in_o2 = True print(i01,i02,'YES') break if not is_in_02: print(i01, ' ', 'NO') for i02 in list02: is_in_01 = False for i01 in
Python两个变量的值进行交换的方法 使用第三方变量: '''这是第一种赋值方法,采用第三方变量''' c = a a = b b = c 使用两个变量: '''使用两个变量''' a = a+b #取两个数的和 b = a-b #然后a-b等于a然后赋值给b a = a-b #然后a-b等于b然后赋值给a,完成值的交换 使用两个变量的另一种方法: a,b = b,a
近期的项目中 涉及到相关知识 就来总结一下 ! 先看源码: def print(self, *args, sep=' ', end='\n', file=None): # known special case of print """ print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False) Prints the values to a stream, or to sys.stdout by defa
