列表元組內置函數用法list
元組的用法和列表相似就不一一介紹了
1）def append(self, p_object):將值添加到列表的最後

return 0

# real signature unknown; restored from __doc__
"""
L.index(value, [start, [stop]]) -> integer -- return first index of value.

"""
return 0
（5）def insert(self, index, p_object):指定下標插入元素
# real signature unknown; restored from __doc__
""" L.insert(index, object) -- insert object before index """
pass
（6）def pop(self, index=None):刪除並返回指定下標的值，如果沒有指定下標最後一個返回

"""
L.pop([index]) -> item -- remove and return item at index (default last).
Raises IndexError if list is empty or index is out of range.
"""
pass
（7）def remove(self, value): 移除列表中的指定值第一個
