Here is a complete example to print first 10 prime numbers in Python using a while loop. def is_prime(num): if num <= 1: return False for i in range(2, int(num**0.5) + 1): if num % i == 0: return False return True ...
python 复制代码 for i in range(5): print(i) count = 0 while count < 5: print(count) count += 1 9. 列表与元组 列表用[]表示,元组用()表示,都用于存储多个元素: python 复制代码 my_list = [1, 2, 3, 4, 5] my_tuple = (1, 2, 3, 4, 5) ...
