1.配置字符串编码出错
# coding:utf-8
import sys
reroad(sys)
sys.setdefaultencoding("utf8")这是python2的写法，python3已经取消了这种方法
1. # coding:utf-8
作用是定义源代码的编码. 如果没有定义, 此源码中是不可以包含中文字符串的.
2. sys.setdefaultencoding()
是设置默认的string的编码格式；
而python2.x的的defaultencoding是ascii,这也就是大多数python编码报错：“UnicodeDecodeError: 'ascii' codec can't decode byte ......”的原因。
而python3中没有
3.python3遇到错误“UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)”的解决方法如下：
方法一：在环境变量中，设置PYTHONIOENCODING=utf-8
方法二：给函数的encoding参数赋值“utf-8”
以python写文件的open方法为例：
fsopen = open(aFileUrl, mode="w", encoding='utf-8')
方法三：给标准输出设置编码
import io , sys
sys.stdout = io.TextIOWrapper(sys.stdout.detach(), encoding='utf-8')
sys.stderr = io.TextIOWrapper(sys.stderr.detach(), encoding='utf-8')
4.UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe5 in position 103339: invalid continuation byte
line.decode("utf8","ignore")
2.pycharm激活

python3.7下载链接：https://www.python.org/ftp/python/3.7.0/python-3.7.0-amd64.exe
1.X86和X86-64的区别
X86：32 bit
X86-64：64bit
2.web-based ,executable , embeddable zipfile区别：
web-based: 透过网络安装的，就是执行安装后才透过网络下载python
executable: 可執行文件的，既把要安装的python全部下载好在本机安装
embeddable zipfile: zip 压缩档，就是python打包成zip压缩包
4.pycharm使用社区版还是专业版的问题
社区版：免费，无需激活
专业版：收费，需要激活
在功能上有差异，对于程序编写没有任何影响，两者都可以安装
