之前用PyCharm去开发Python，体验很好，就是IDE太重了，资源消耗有点多。
之前已经试了试轻量级的VSCode的调试Python的效果：
现在有机会去，继续用VSCode去开发Python代码，试试感觉如何：
好像还不错
继续去试试。
先去处理json加载
python json
用如下代码：
<code>#!/usr/bin/python
# -*- coding: utf-8 -*-
BookJsonTemplateFilename = "book_common.json"
CurrentGitbookName = "youdao_note_summary"
BookJsonCurrentFilename = "book_current.json"
import os
import json
templateJson = {}
currentJson = {}
currPath = os.getcwd()
print("currPath=%s" % currPath)
bookJsonTemplateFullPath = os.path.join(currPath, BookJsonTemplateFilename)
print("bookJsonTemplateFullPath=%s" % bookJsonTemplateFullPath)
# /Users/crifan/GitBook/Library/Import/book_common.json
with open(bookJsonTemplateFullPath) as templateJsonFp:
templateJson = json.load(templateJsonFp)
# print("type(templateJson)=%s" % type(templateJson)) #type(templateJson)=<type 'dict'>
bookJsonCurrentFullPath = os.path.join(currPath, CurrentGitbookName, BookJsonCurrentFilename)
print("bookJsonCurrentFullPath=%s" % bookJsonCurrentFullPath)
with open(bookJsonCurrentFullPath) as currentJsonFp:
currentJson = json.load(currentJsonFp)
print("templateJson=%s" % templateJson)
print("currentJson=%s" % currentJson)
</code>可以加载已有的两个json文件并打印内容了：
去把Python从2.7.10换成3.6:
出现提示是否安装pylint，点击Install：

这样就能用
import pprint
了。
然后再去想办法看看，如何合并json，或者说dict：
然后再去：
【已解决】python中把dict的json输出到文件且带缩进和不要unicode的\uxxxx
如此，才可以生成所需要的book.json
但是字段的顺序，不是希望的。所以再去：
【部分解决】Python输出dict（json）到文件中时确保或指定字段的顺序
至此，用VSCode去调试Python，效果还是不错的。
此处用到的一些功能：
【调试的快捷键】
开始调试：F5
停止：Shift+F5
重新开始：Command+Shift+F5
单步（跳过）：F10
【点击行首添加断点】
【console终端】
清除之前的log：
右键-》清除
==Command+K
VSCode调试Python总体感觉：
速度快
方便好用
不过功能上，还是没有PyCharm强大。
结论：
对于普通小项目，文件少的话，用VSCode，已经算很不错了。
很大的项目，再考虑用PyCharm。
