对于一个混子来说,我从飞✈桨学到了很多python方面的知识,也从一个python小白变成了一个进阶小白。
以下均为笔记,代码来自原课程

python基础1.1 数据类型1.1.1 列表 list

list是一种有序的集合,可以随时添加和删除其中的元素。

list1 = [1, 2, 3, 4, 5 ] list2 = ["a", "b", "c", "d","e","f"] list3 = ['physics', 'chemistry', 1997, 2000] len(list1) list1[4] list3.append(5) list1.pop() 1234567891.1.2 元组 tuple

另一种有序列表叫元组:tuple。tuple和list非常类似,但是tuple一旦初始化就不能修改

tuple1 = (1, 2, 3, 4, 5 ) tuple2 = ("a", "b", "c", "d","e","f") tuple3 = ('physics', 'chemistry', 1997, 2000) len(tuple1) tuple1.append(3) 123451.1.3 集合 set

set和dict类似,也是一组key的集合,但不存储value。由于key不能重复,所以,在set中,没有重复的key。

s = {1,1,2,3,4} 11.2 流程控制1.2.1 条件判断

light = '红灯' if light == '红灯': print('停') elif light == '绿灯': print('行') else: print('等一等') 123456781.2.2 循环

#猜数字小游戏 my_number = 3200 # 这是真实的价格 guess_number = input('这台冰箱多少钱?') # 所有符号都是英文标点(半角字符) guess_number = int(guess_number) while guess_number != my_number: if guess_number<my_number: # 使用缩进来标识代码段 guess_number = input('猜低了!再猜') guess_number = int(guess_number) else: guess_number = input('猜高了!再猜') guess_number = int(guess_number) print(' 恭喜您,猜对了! ') 123456789101112

fruits = ['banana', 'apple', 'mango'] for fruit in fruits: # 第一个实例 print( '当前水果 :', fruit) 1231.2.3 break continue pass

#break my_number = 3200 # 这是真实的价格 guess_number = input('这台冰箱多少钱?') guess_number = int(guess_number) while True: if guess_number<my_number: guess_number = input('猜低了!再猜') guess_number = int(guess_number) elif guess_number>my_number: guess_number = input('猜高了!再猜') guess_number = int(guess_number) else: break print(' 恭喜您,猜对了! ') 123456789101112131415

# continue : 跳过本轮 # 打印1-10中的偶数 for i in range(10): num = i 1 if num%2 != 0: continue print(num) print(num**2) 123456789

# pass: 占位,还没想好怎么写,先让程序跑起来 for i in range(5): pass ,
