启动：

config.js

```js
{
    entry: require('./middlewares/orchestrator').entry,
        opts: {
            kubernetes: {
                url: ANXINCLOUD_K8S_API || 'https://10.8.30.157:6443',

        }
}
```

新的名称 Jupyter 由`Julia`、`Python` 和 `R` 组合而成

安装使用

```sh
pip3 install jupyter
# 使用帮助
jupyter notebook -h

# 启动
jupyter notebook
```

访问 http://localhost:8888/

![image-20210927091813110](imgs/安心云数据分析工具/image-20210927091813110.png)



修改文件路径

```sh
jupyter notebook --generate-config
 
# file:///C:/Users/yww08/.jupyter/jupyter_notebook_config.py
# c.NotebookApp.notebook_dir = 'E:/tmp/notebook'
```



Magic操作（基于IPython）

```python
%%timeit
测算整个单元格的运行时间
```

【MicroK8S】 [Github](https://github.com/ubuntu/microk8s)

Install MicroK8s with:

<font color='red' size='5'>尝试失败了!!!</font>

```
snap install microk8s --classic
```

MicroK8s includes a `microk8s kubectl` command:

```
sudo microk8s kubectl get nodes
sudo microk8s kubectl get services
```

To use MicroK8s with your existing kubectl:

```
sudo microk8s kubectl config view --raw > $HOME/.kube/config
```

将用户添加如 microk8s用户组，以实现对k8s的访问

```
sudo usermod -a -G microk8s <username>
```

Kubernetes插件

MicroK8s installs a barebones upstream Kubernetes. Additional services like dns and the Kubernetes dashboard can be enabled using the `microk8s enable` command.

```
sudo microk8s enable dns dashboard
```

Use `microk8s status` to see a list of enabled and available addons. You can find the addon manifests and/or scripts under `${SNAP}/actions/`, with `${SNAP}` pointing by default to `/snap/microk8s/current`.

#Python3.X 源码文件默认使用utf-8编码，所以可以正常解析中文，无需指定 UTF-8 编码。

字典 dict1 = { 'abc': 456 }
集合 a = set('abracadabra') 或者 可以用大括号({})创建集合。注意：如果要创建一个空集合，你必须用 set() 而不是 {} ；后者创建一个空的字典，下一节我们会介绍这个数据结构。

笔记

```python
a,b=0,1
while b<10:
	print(b,end=',')
	a,b=b,a+b
    
print()
# while else 循环
c=0
while c<10:
    print(c)
    c+=2
else:
    print("after c=",c)
    
# set顺序是乱的
chars=set('abcdefg')
for c in chars:
    print(c)
    
# range([start,]stop[,step])
for i in range(5,21,2):
    print(i)
    
# for array
a=['a','b','c']
for i in range(len(a)):
    print(i,':',a[i]);
    
# 空语句 可以用pass占位

## 迭代器
a=[1,2,3,4]
it=iter(a)
print(next(it))
for i in it:
    print('in range:',i)
    
# while next 写法
import sys
list=[1,2,3,4]
it = iter(list)    # 创建迭代器对象
 
while True:
    try:
        print (next(it))
    except StopIteration:
        print ('finished')
        break
        #sys.exit()
        
print('is here?')

# 通过yield生成斐波那契数列
def fibonacci(n):
    a,b,count=0,1,0
    while True:
        if (count>n):
            return
        yield a
        a,b=b,a+b
        count+=1
        
f=fibonacci(10)
for fi in f:
    print('f',fi,end=',')
    

# 函数
def hello() :
    print("Hello World!")

ret=hello()
print('ret:'+str(ret))

'''
不可变类型：strings,tuples,numbers  作为函数参数类似C++中值传递
可变类型: list,dict 作为函数参数类似C++中的引用传递

参数可以按名称传递、可以有默认值
可变长参数如下
'''
def printinfo(arg1,*vartuple):
    print(arg1)
    print(len(vartuple))
printinfo(7)

# 加了两个星号 ** 的参数会以字典的形式导入。

sum=lambda a,b:a+b
print(sum(1,20))

# 列表推导式
vec=[2,4,6]
dd=[3*x for x in vec]
print(dd)

# 字典的便利
dics={'name':'ww','age':18}
for k,v in dics.items():
    print(k,'=',b)
    
# 遍历技巧
# for i,v in enumerate(list) 同时获得索引和值
# zip(list1,list2) 组合两个序列
# reversed(seq) 反向
# sorted(seq) 排序

## 类型转换
# int(x[, base]) 将x转换为一个整数，base为进制，默认十进制
#
# long(x[, base] ) 将x转换为一个长整数
#
# float(x) 将x转换到一个浮点数
#
# complex(real[, imag])  创建一个复数
#
# str(x) 将对象 x 转换为字符串
#
# repr(x) 将对象 x 转换为表达式字符串
#
# eval(str)  用来计算在字符串中的有效Python表达式, 并返回一个对象
#
# tuple(s) 将序列 s 转换为一个元组
#
# list(s) 将序列 s 转换为一个列表
#
# set(s) 转换为可变集合
#
# dict(d) 创建一个字典。d 必须是一个序列(key, value) 元组。
#
# frozenset(s) 转换为不可变集合
#
# chr(x) 将一个整数转换为一个字符
#
# unichr(x) 将一个整数转换为Unicode字符
#
# ord(x) 将一个字符转换为它的整数值
#
# hex(x) 将一个整数转换为一个十六进制字符串
#
# oct(x)  将一个整数转换为一个八进制字符串
```

模块学习：

`m.py`

```python
# !/usr/bin/python3
if __name__=='__main__':
    # 程序独立运行
    pass
else:
    # 程序被模块调用
    print('moduled')
    
def fabonacci(n):
    a,b,c=0,1,0
    while c<n:
        yield b
        a,b=b,a+b
        c+=1
```

调用模块：

```python
import m

ret=m.fabonacci(10)

for r in ret:
    print(r)
```



包的概念：

文件夹 包含 `__init__.py` 

```
sound/                          顶层包
      __init__.py               初始化 sound 包
      formats/                  文件格式转换子包
              __init__.py
              wavread.py
              wavwrite.py
              aiffread.py
              aiffwrite.py
              auread.py
              auwrite.py
              ...
      effects/                  声音效果子包
              __init__.py
              echo.py
              surround.py
              reverse.py
              ...
      filters/                  filters 子包
              __init__.py
              equalizer.py
              vocoder.py
              karaoke.py
              ...
```

导入方法中`from package import item`，item既可以是子模块（子包），也可以是包里面定义的内容（函数或变量）

导入方法中`from sound.effects import *`  如果这个包里面有子模块，需要定义 `__all__`变量来说明

```
__all__ = ['echo','surround','reverse']
```



输入输出 和 文件操作

```python
# rjust 右对齐
for x in range(1,11):
    print(repr(x).rjust(2),repr(x*x).rjust(3),repr(x*x*x).rjust(4),end=' ') 
    print()
    
print('name is {0},age {1},alias {alias}'.format('ww',18,alias='peter'))

# 读文件
with open('foo.txt','r') as f:
    # 也可以 f.readlines / f.read(length)
    for line in f:
        print (line,end='')

print(f.closed)

# 写文件
with open('bar.txt','w') as f:
    for a in range(0,10):
        f.write(str(a))

f=open('bar.txt','r')
print(f.readlines())
f.close

# 通过pickle实现序列化和反序列化
import pickle,pprint

data1={
    'a':[1,2.0,4+3j],
    'b':('text',u'unicode text'),
    'c':None
}

selfref_list = [1, 2, 3]
selfref_list.append(selfref_list)

output=open('data.pk1','wb')
pickle.dump(data1,output)
pickle.dump(selfref_list,output,-1)
output.close()

# 反序列化
input=open('data.pk1','rb')
data1=pickle.load(input)
pprint.pprint(data1)
pprint.pprint(pickle.load(input))
```



错误异常

st = student('ak',16,'g3')
st.speak()
super(student,st).speak() # 调用父类已被覆盖的方法

作用域：

Python 中只有模块（module），类（class）以及函数（def、lambda）才会引入新的作用域，其它的代码块（如 if/elif/else/、try/except、for/while等）是不会引入新的作用域的，也就是说这些语句内定义的变量，外部也可以访问，如下代码：

```python

```

global 和 nonlocal关键字用于在指定作用域内修改全局或闭包外部作用域内的变量



### 标准库 [官方中文文档目录](https://docs.python.org/zh-cn/3.7/library/index.html)

HTTP请求

```python
from urllib.request import urlopen
for line in urlopen('http://baidu.com'):
    line = line.decode('utf-8')
    print(line)
    
# pip install requests

日志

```python

# logging.debug(msg, *args, **kwargs)	
log.warning('hello')

# 输出 日志级别:日志器名称:日志内容

t=Timer(4.0,hello)
t.start()

while True:
    time.sleep(1)
```
