""" L.append(object) -> None -- append object to end """
pass
append函数将字符串插入到列表自身的末尾
def clear(self): # real signature unknown; restored from __doc__
""" L.clear() -> None -- remove all items from L """
pass
clear函数将清除list所有元素
def copy(self): # real signature unknown; restored from __doc__
""" L.copy() -> list -- a shallow copy of L """
return []
copy函数将自身拷贝并返回
def count(self, value): # real signature unknown; restored from __doc__
""" L.count(value) -> integer -- return number of occurrences of value """
return 0
count函数统计list的元素个数
def extend(self, iterable): # real signature unknown; restored from __doc__
""" L.extend(iterable) -> None -- extend list by appending elements from the iterable """
pass
extend函数将可迭代对象的所有元素插入到自身。
def index(self, value, start=None, stop=None): # real signature unknown; restored from __doc__

Raises ValueError if the value is not present.

return 0
index方法从字符串中查找与参数2匹配的字符串的第一个位置返回
def insert(self, index, p_object): # real signature unknown; restored from __doc__
""" L.insert(index, object) -- insert object before index """

def pop(self, index=None): # real signature unknown; restored from __doc__
"""
L.pop([index]) -> item -- remove and return item at index (default last).

Raises ValueError if the value is not present.
"""
pass
remove函数将参数2指定的值得元素删除。
def reverse(self): # real signature unknown; restored from __doc__
""" L.reverse() -- reverse *IN PLACE* """
pass
reverse函数将列表的元素反向排序
def sort(self, key=None, reverse=False): # real signature unknown; restored from __doc__
""" L.sort(key=None, reverse=False) -> None -- stable sort *IN PLACE* """
pass
sort函数将列表的数据进行排序,但是只能对同一个数据类型的列表进行排序,如果数字,字母,符号一起排序就会报错。
