Python学习（一）
一：开发工具安装
1,pycharm下载：Linux版本
2，破解：在help-register下-service输入：
http://elporfirio.com:1017/或 http://idea.imsxm.com/
二：常用插件下载及安装：
1，下载安装pip
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
sudo python get-pip.py
2,下载安装setuptools
wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
sudo apt-get install python-setuptools
3，安装networkx和numpy和matplotlib
sudo pip install networkx
sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose
4,安装py4j，由于后面要用spark
sudo pip install py4j
5,pyCharm配置spark
打开PyCharm，创建一个Project。 然后选择“Run” ->“Edit Configurations” ->“Environment variables” 增加SPARK_HOME目录与PYTHONPATH目录。 - SPARK_HOME:Spark安装目录 - PYTHONPATH:Spark安装目录下的Python目录
6,两个例子
from pyspark import SparkContext sc = SparkContext("local", "test") rdd = sc.parallelize([1, 2, 3, 4]) print "rdd.collect():%s", str(rdd.collect())
import networkx as nx import matplotlib.pyplot as plt def draw_graph(graph): # extract nodes from graph nodes = set([n1 for n1, n2 in graph] + [n2 for n1, n2 in graph]) # create networkx graph G=nx.Graph() # add nodes for node in nodes: G.add_node(node) # add edges for edge in graph: G.add_edge(edge[0], edge[1]) # draw graph pos = nx.shell_layout(G) nx.draw(G, pos) # show graph plt.show() # draw example graph = [(20, 21),(21, 22),(22, 23), (23, 24),(24, 25), (25, 20)] draw_graph(graph)
