print(num, “is an Armstrong number”) else: print(num, “is not an Armstrong number”) ▍50、用一行Python代码,从给定列表中取出所有的偶数和奇数 a = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] odd, even = [el forel ina ifel % 2== 1], [el forel ina ifel % 2== 0] print(...
This means that only a reference to the function is passed. The function isn’t executed. The greet_bob() function, on the other hand, is written with parentheses, so it will be called as usual.This is an important distinction that’s crucial for how functions work as first-class ...
