1、列表

　　格式：llist=[a,b,c,d,1,2,3,4];a=[]为空 ，a[:]为列表本身，但存储位置不同 在赋值后b1=id(a）与 b2=id(a[:])不同，　

　　len([1, 2, 3]) --长度
　　[1, 2, 3] + [4, 5, 6] --组合
　　['Hi!'] * 4 --重复
　　3 in [1, 2, 3] True --元素是否存在于列表中
　　for x in [1, 2, 3]: print(x, end=" ") --迭代(不换行)
　　a[1,2,3];b['a','b','c']; c=[a,b];c[0,0]=1 --嵌套

　　a[1:2]代表第2，3个值；

　　#末尾添加
　　list.append(obj)
　　#列表倒置
　　list.reverse()

　　#循环嵌套

　　for  I in range（5）:

　　　　for r in i:

 

 

 

task1  编写一段有26个字母对应的莫斯密码表  ，并自定义一段内容用于示例

#摩斯密码表
morse_code_list = [".-","-...","-.-.","-..",".","..-.",
                   "--.","....","..",".---",
                   "-.-",".-..","--","-.","---",".--.",
                   "--.-",".-.","...","-","..-","...-",
                   ".--","-..-","-.--","--.."]
#a-z字符串
letter_str = 'abcdefghijklmnopqrstuvwxyz'
#要发送的内容
word = ['fight','with','you']
result=''
#遍历取得要发送的内容在字符串的位置，与摩斯密码表位置对应
for i in word:
    for r in i:
        letter_str_index = letter_str.index(r)
        morse_code = morse_code_list[letter_str_index]
        result = result + morse_code +'|'
print(result)
