列表的索引步长和str一样，切片也是列表的增删改查
列表的基础操作：
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.append('xiaomage')
print(zhang)
.append()给一个列表追加一个参数（就是在末尾）
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.insert(1,'xiaomage')
print(zhang)
.insert()给一个列表插入一个参数（跟索引和插入的东西）
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.extend('xiaomage')
print(zhang)
.extend()可迭代增加，说白了就是把你输入的东西全部加进去
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.pop(0)
print(zhang)
.pop()按照索引删除对象，有返回值，返回值就是你删除的那个东西
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.remove('zhangbaocheng')
print(zhang)
.remove()按照元素去删除
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang.clear()
print(zhang)
.clear()清空列表
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
del zhang[1]
print(zhang)
del zhang[::2]
print(zhang)
del 删除，可以按照索引和切片删除，
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang[ 0 ] = 'yiersan'
print(zhang)
列表名+[索引] = 字符串之类的（或者其它你想改的东西） 改列表内容 （每次只能改一个）
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang[:] = 'yiersan'
print(zhang)
列表名 + 切片 = 字符串之类的（或者其它你想改的东西） 改列表内容
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu']
zhang[::2] = 'zh'
print(zhang)
列表名 + 切片 = 字符串之类的（或者其它你想改的东西） 改列表内容，但是这个有长度限制，
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu','zhangdabiao']
print(zhang.count('zhangdabiao'))
.count()和字符串里面的count一样，用来计算列表中字符串出现的次数
zhang = ['zhangbaocheng','zhangdabiao','gongzhangguyuewenwu','zhangdabiao']
print(zhang.index('zhangdabiao'))
.index（）和字符串里面的index一样，用来查找改字符串的索引，也可以切片
shuzi['3712','321313','21321','312','4','55','65','54','6','56']
shuzi.sort()
shuzi.sort(reverse=True)
print(shuzi)
.sort()将数字由小到大排序(默认)，可以在里面添加参数reverse=True让其由大到小
shuzi = ['3712','321313','21321','312','4','55','65','54','6','56']
shuzi.reverse()
print(shuzi)
.reverse()将列表里面内容翻转过来（也就是倒过来）
shuzi = ['3712','321313','21321','312','4','55','65','54','6','56']
print(len(shuzi))
len()和字符串里面的一样，测量里面一共有多少个元素/字符串/或者其它组成部分
z = ['sdadisaojd','dsadsadads','dafqwqfgfeds']
z[0] = z [0].upper()
print(z)
.upper()/lower()和字符串里面的一样，将某个元素改成大/小写
l = range(1,6)
print(l)
for i in l:
print(i)
range和列表基本一样，但是不能直接通过print来看，需要使用for循环来看，个人觉得吧，更像是一个集合
在列表能运用的东西在range里面同样可以，比如切片，索引等
