输出1到100之间的所有奇数和偶数：
代码语言：javascript复制 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：
代码语言：javascript复制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：
代码语言：javascript复制#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：
代码语言：javascript复制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
