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：

#print("hello world.",end="__") # n rn r#print("hello world.",end="__")#print("hello world.",end="__") num1 = 0 while num1=5: print(num1,end="_") num2 = 0 while num2=7: print(num2,end="-") num2+=1 num1+=1 print() # print(end="n") #0_0-1-2-3-4-5-6-7-#1_0-1-2-3-4-5-6-7-

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
