实际上Python 内部提供的module 可以分成两类,一类是C 实现的builtin module 如thread,一类是用python 实现的标准库module。 p328:设置搜索路径、site-specific 的 module 搜索路径 sys.path 即 sys.__dict__['path'] 是一个 PyListObject 对象,包含了一组PyStringObject 对象,每一个对象是一个module 的搜索...
1.整型 int 2.浮点型 float 3.字符串 str 4.布尔型 bool 5.列表 list 6.元组 tuple 7.字典 dict 2.查看数据类型使用type() eg:age = 18 type(age) 基本上会用内置函数instance()去判断类型 #查看数据类型age = 18gender='boy'print(type(age))#intprint(isinstance(gender,str))#Trueprint(isinstanc...
tuple -> () # tuple is a like a list but you cannot change the values in a tuple once it's defined. Tuples are good for storing information whose elements shouldn't be changed throughout the life of a program. Deque deque is preferred over a list in the cases where we need quicker...
Python offers a straightforward approach that involves iterating over each item in the list and checking for a match to find if an element exists in the list using a loop. This method is particularly useful when you need to perform additional operations on matching elements or when working ...

In this code, we create an instance of it directly by applying it to the listA. To determine the mode, we use themost_common(1)method, which returns a list containing the element with the highest frequency and its count. By accessing the first element of this list with[0][0], we ob...
