一. 添加
1.append(data) 把添加的值直接當(dāng)做一個(gè)元素插入列表當(dāng)中
In [1]: list = ['zi','lie','chuan']
In [2]: list
Out[2]: ['zi', 'lie', 'chuan']
In [3]: list.append('zi')
In [4]: list
Out[4]: ['zi', 'lie', 'chuan', 'zi']
2.extend(data) 會(huì)把添加的值拆開成元素，分別插入到列表當(dāng)中
In [7]: list
Out[7]: ['zi', 'lie', 'chuan', 'zi']
In [8]: list.extend('lie')
In [9]: list
Out[9]: ['zi', 'lie', 'chuan', 'zi', 'l', 'i', 'e']
3.insert(position,data) position 索引
In [10]: lisy = ['zi','lie', 'chuan',]
In [11]: list
Out[11]:['zi', 'lie', 'chuan', 'zi', 'l', 'i', 'e']
In [12]: list.instert(2,'ding')
