copy(深浅拷贝)

import copy
字符串,整数,浮点,列表,元组(深浅拷贝都一样)
‘‘‘
a1 = 1223444
a2 = a1
print(id(a1))
print(id(a2))
‘‘‘
a1 = 123444
‘‘‘

‘‘‘
a2=copy.deepcopy(a1)
print(id(a1))

当出现下面这种情况,包涵多个子值时,浅拷贝只会拷贝第一层的内存地址,而深拷贝则会拷贝除最后一层外所有。

n1 = {‘k1‘:‘v1‘,‘k2‘:‘v2‘,‘k3‘:[‘wjh‘,223,]}
‘‘‘
print(id(n1))
n2 = n1
print(id(n2))
‘‘‘
监控模板调用例子:
#n2 = copy.copy(n1)
n2 = copy.deepcopy(n1)
#print(id(n1[‘k3‘]))
#print(id(n2[‘k3‘]))

    ‘cpu‘:[80,],
    ‘mem‘:[80,],

    server = smtplib.SMTP("smtp.126.com", 25)
    server.login("wptawy@126.com", "邮箱密码")
    server.sendmail(‘wptawy@126.com‘, [user,], msg.as_string())
    server.quit()
mail(‘133130355@qq.com‘)
默认参数:

def func(name, age = 18):

    print ("%s:%s" %(name,age))

# 指定参数
func(‘wupeiqi‘, 19)
# 使用默认参数

func(‘alex‘)

动态参数:
*

def pr(*args):
    print(args)
wjh=[‘1‘,‘2‘]
pr(wjh)
*可以传递元组,字符,列表

**
def pr(**args):
    print(args)
pr(wjh={‘wjh‘:‘123‘,})
**可以传递字典

def pr(*args,**kwargs):
    print(args)
    print(kwargs)
pr([1,2,3,4],wjh={‘wjh‘:‘123‘,})
当两个参数都存在时一定要先写*的

 双向队列:

可以将值从左右提取插入。

import collections

d = collections.deque()
d.append(‘1‘)
d.appendleft(‘10‘)
d.appendleft(‘1‘)
print(d)
print(d.count(‘1‘))
d.extend([‘y‘,‘yy‘,‘n‘])#扩展
d.extendleft([‘t‘,‘1‘])
d.rotate(1) #将最后一个值放到第一个

单向队列:
只能将值从左到右传入,取出,(类似子弹夹原理)

import queue
#qsize:查看队列元素个数
#empty:清除
#full:是否填满
#put:插入数据
#get:取数据
q = queue.Queue()
q.put(‘123‘)
q.put(‘456‘)
print(q.qsize())
print (q.get())

 字典(扩展)

有序字典:

import collections
dic = collections.OrderedDict()
dic[‘a‘] = ‘a1‘
dic[‘b‘] = ‘b1‘
dic[‘c‘] = ‘c1‘
print(dic)
通过列表去像字典传输元素,以达到有顺序。

默认字典:

dic = collections.defaultdict(list)定义默认字典的元素为list。
#dic={}
a = [11,22,33,44,55,66,77,88,99]
for i in a:
    if i >66:
        dic[‘k1‘].append(i)
    else:
        dic[‘v2‘].append(i)


可命名元组:
print(dic)name_tuple=collections.namedtuple(‘name_tuple‘,[‘x‘,‘y‘,‘z‘])
tuple1=name_tuple(11,22,33)
print(tuple1.x)
print(tuple1.y)

new_li=filter(fuc,li1)

 lambda表达式

学习条件运算时,对于简单的 if else 语句,可以使用三元运算来表示,即:

# 普通条件语句
if 1 == 1:
    name = ‘wupeiqi‘
else:
    name = ‘alex‘
   
# 三元运算
name = ‘wupeiqi‘ if 1 == 1 else ‘alex‘

对于简单的函数,也存在一种简便的表示方式,即:lambda表达式

# ###################### 普通函数 ######################
# 定义函数(普通方式)
def func(arg):
    return arg + 1
   
# 执行函数
result = func(123)
   
# ###################### lambda ######################
   
# 定义函数(lambda表达式)
my_lambda = lambda arg : arg + 1
   
# 执行函数
result = my_lambda(123)

lambda存在意义就是对简单函数的简洁表示

 文件操作

open函数,该函数用于文件处理

操作文件时,一般需要经历如下步骤:

  • 打开文件
  • 操作文件

一、打开文件

1
文件句柄 = open(‘文件路径‘, ‘模式‘)

打开文件时,需要指定文件路径和以何等方式打开文件,打开后,即可获取该文件句柄,日后通过此文件句柄对该文件操作。

打开文件的模式有:

  • r,只读模式(默认)。
  • w,只写模式。【不可读;不存在则创建;存在则删除内容;】
  • a,追加模式。【可读;   不存在则创建;存在则只追加内容;】

"+" 表示可以同时读写某个文件

  • r+,可读写文件。【可读;可写;可追加】
  • w+,写读
  • a+,同a

"U"表示在读取时,可以将 \r \n \r\n自动转换成 \n (与 r 或 r+ 模式同使用)

  • rU
  • r+U

"b"表示处理二进制文件(如:FTP发送上传ISO镜像文件,linux可忽略,windows处理二进制文件时需标注)

  • rb
  • wb
  • ab
  • 二、操作

      4         """
      5         Character and line based layer over a BufferedIOBase object, buffer.
      6         
      7         encoding gives the name of the encoding that the stream will be
      8         decoded or encoded with. It defaults to locale.getpreferredencoding(False).
      9         
     10         errors determines the strictness of encoding and decoding (see
     11         help(codecs.Codec) or the documentation for codecs.register) and
     12         defaults to "strict".
     13         
     14         newline controls how line endings are handled. It can be None, ‘‘,
     15         ‘\n‘, ‘\r‘, and ‘\r\n‘.  It works as follows:
     16         
     17         * On input, if newline is None, universal newlines mode is
     18           enabled. Lines in the input can end in ‘\n‘, ‘\r‘, or ‘\r\n‘, and
     19           these are translated into ‘\n‘ before being returned to the
     20           caller. If it is ‘‘, universal newline mode is enabled, but line
     21           endings are returned to the caller untranslated. If it has any of
     22           the other legal values, input lines are only terminated by the given
     23           string, and the line ending is returned to the caller untranslated.
     24         
     25         * On output, if newline is None, any ‘\n‘ characters written are
     26           translated to the system default line separator, os.linesep. If
     27           newline is ‘‘ or ‘\n‘, no translation takes place. If newline is any
     28           of the other legal values, any ‘\n‘ characters written are translated
     29           to the given string.
     30         
     31         If line_buffering is True, a call to flush is implied when a call to
     32         write contains a newline character.
