<Python初学>基本数据list的操作

Methods defined here:

def append(self, p_object):
# real signature unknown; restored from __doc__
# 在列表的末尾添加元素p_object.
""" L.append(object) -> None -- append object to end """
pass

def clear(self):
# real signature unknown; restored from __doc__
# 删除所有在列表里的元素
""" L.clear() -> None -- remove all items from L """
pass

def copy(self):
# real signature unknown; restored from __doc__
""" L.copy() -> list -- a shallow copy of L """
return []

def count(self, value):
# real signature unknown; restored from __doc__
# 统计列表中value的个数并将其返回
""" L.count(value) -> integer -- return number of occurrences of value """
return 0

def extend(self, iterable):
# real signature unknown; restored from __doc__
# 将iterable(可迭代的：list,dict,tuple)扩展到列表中末尾
# P.s.：dict只添加key
""" L.extend(iterable) -> None -- extend list by appending elements from the iterable """
pass

def index(self, value, start=None, stop=None):
# real signature unknown; restored from __doc__
# 在列表的[start:stop]区间返回value第一次出现的index
"""
L.index(value, [start, [stop]]) -> integer -- return first index of value.
Raises ValueError if the value is not present.
"""
return 0

def insert(self, index, p_object):
# real signature unknown; restored from __doc__
# 在index位置插入p_object
""" L.insert(index, object) -- insert object before index """
pass

def pop(self, index=None):
# real signature unknown; restored from __doc__
# 弹出L[index]，默认弹出末尾元素
"""
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

def remove(self, value):
# real signature unknown; restored from __doc__
# 移除列表中第一个value，如果不存在则报错
"""
L.remove(value) -> None -- remove first occurrence of value.
Raises ValueError if the value is not present.
"""
pass

def reverse(self):
# real signature unknown; restored from __doc__
# 倒置列表
""" L.reverse() -- reverse *IN PLACE* """
pass

def sort(self, key=None, reverse=False):
# real signature unknown; restored from __doc__
# 将list排序，key为排序关键字， reverse= TRUE 为逆序
""" L.sort(key=None, reverse=False) -> None -- stable sort *IN PLACE* """
pass
