python while循环
输出1到100之间的所有奇数和偶数：
| num = 1 while num <=100: if num%2 == 0: print(num) num += 1 cai num = 1 while num <=100: if num%2 == 1: print(num) num += 1 |
猜年龄游戏的两种方法：
| age = 50 flag = True while flag: user_input_age = int(input("Age is:")) if user_input_age == age: print("Yes") flag = False elif user_input_age > age: print("is bigger") else: print("is smaller")print("End") age = 50 while True: user_input_age = int(input("Age is:")) if user_input_age == age: print("Yes") break elif user_input_age > age: print("is bigger") else: print("is smaller")print("End") |
break语句和continue语句。
print中的end语句：
输出#号，指定长高的长方形：
| height = int(input("height:"))width = int(input("width:")) num_height = 1 while num_height <= height: num_width = 1 while num_width <= width: print("#",end="") num_width += 1 print() num_height += 1 |
