变量
一个由程序员或用户定义的量且在程序中可能发生改变的量
#变量是所有程序的起点
变量的分类:
不可变型:无法对变量内的某一个单一元素进行修改、增加、删除
字符串 - str - string - “变量”
整数 - int - integer - 100
浮点 - float - float - 3.111 1.0
元组 - tuple - tuple - (1,2,"a","好")
可变型:可以对变量内的某一个单一或多个元素进行修改、增加、删除
字典 - dict - dictionary - {"name":"张三","age":"33"}
列表 - list - list - [1,2,"张三","a"]
赋值
从右向左赋值
name = "张三"
name_list = ["张三","a"]
变量名字 —映射— 内存地址 — 内存存储
name —— 2131231 “张三”
变量的命名规则:
强制性规则
1、变量开头不能是数字
2、特殊字符不能出现在变量中( 除_ 外)
3、变量名称不能出现空格
4、变量名区分大小写A和a是两个变量
约定俗称的规则
1、大驼峰 (ClassName一般用做类名)
2、小驼峰 (defName一般用做方法名)
3、下划线分割 (t_name一般用做变量名)
4、不用0(零)和o(O)作为开头或结尾
import string
import random
name = 'gaobo'
sex = 'nv'
nia = 'nan'
high = 3
print("姓名%s,性别%s,年龄%s,身高%.2f" % (name, sex, nia, high))
list2 = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
addlis = []
for i in range(8):
qu = list2[random.randint(0, len(list2)-1)]
print(qu)
addlis.append(qu)
print(addlis)
print("我的提取码:", "".join(addlis))
qu_li = "".join(random.sample((string.ascii_lowercase + string.digits), 10))
print("我的提取码:", qu_li)
