我想要查询列表中嵌套的列表的特定元素是否含有该怎么做
eg:[["X","O"],["","X"]] 判断该列表中是否含有“"
如果你想判断嵌套列表中是否包含特定的元素,那么你可以使用 Python 的 in 操作符,例如:
nested_list = [["X","O"],["","X"]]
if "" in nested_list:
print("The nested list contains an empty string.")
注意,如果你想判断一个嵌套列表中是否包含另一个列表,那么你需要使用一个循环来枚举嵌套列表的每个元素,并判断这些元素是否与你要查找的列表相同:
nested_list = [["X","O"],["","X"]]
search_list = ["","X"]
found = False
for element in nested_list:
if element == search_list:
found = True
break
if found:
print("The nested list contains the search list.")
else:
print("The nested list does not contain the search list.")
上面的代码会在嵌套列表中找到第二个列表时输出“The nested list contains the search list.”。
