循环
while
'''
找出一个数字
余 3 等于 2
余 5 等于 3
余 7 等于 2
'''
number = 1
none = True
while none:
number += 1
if number % 3 == 2 and number % 5 == 3 and number % 7 == 2:
none = False
print("这个数字 number == " ,number)
for
1- 遍历列表
'''
遍历列表
'''
l1 = [1,2,"abc","kdjf",55.555]
len = len(l1)
for item in l1:
index = l1.index(item)
if index < len - 1 :
print(item, end="---")
else:
print(item)
2- 遍历range
'''
内置函数 range(0,10,2)
参数1: 从0开始;
参数2: 不超过10;
参数3: 步长为2;
'''
for i in range(1,10,2):
print(i,end="#")
3- 遍历字符串
'''
遍历字符串
'''
str = "hello world"
for ch in str:
print(ch,end="-")
4- 九九乘法表
'''
九九乘法表
'''
for i in range(1,10):
for j in range(1,i + 1):
print(j,"*",i,"=",i * j ,"\t",end="")
print()
5- 逢7拍大腿游戏
'''
逢 7 拍腿游戏
只要是 7 的倍数 或者 7结尾
'''
l1 = list()
for i in range(-22,100):
if i % 7 == 0 or str(i).endswith("7") > 0 :
l1.append(i)
continue
print(len(l1))
print(l1)
结果:
27
[-21, -17, -14, -7, 0, 7, 14, 17, 21, 27, 28, 35, 37, 42, 47, 49, 56, 57, 63, 67, 70, 77, 84, 87, 91, 97, 98]
6- 猜数字游戏
'''
猜数字游戏
'''
min_number = 0
max_number = 100
thunder_number = 0
guess_number = 0
thunder_number = int(input("请输入雷数字:"))
while True:
guess_number = int(input("请输入您猜的数字:"))
#判断您说的数字是否有效
if guess_number > max_number or guess_number < min_number:
print("您说的数字无效,请重试!%d 到 %d" % (min_number,max_number))
continue
else:
#判断是否猜中
if thunder_number == guess_number:
print("恭喜您猜中!游戏结束")
break
else:
#如果没有猜中重新设置范围
if guess_number > thunder_number:
max_number = guess_number
elif guess_number < thunder_number:
min_number = guess_number
print("您没有猜中,游戏继续,{}到{}".format(min_number,max_number))
