在这里编程新手.每当我尝试在Python IDLE中"导入pprint"时,我都会收到以下错误:

>>> import pprint
Traceback (most recent call last):
  File "<pyshell#21>", line 1, in <module>
    import pprint
  File "C:\Python34\pprint.py", line 10, in <module>
    pprint(count)
NameError: name 'pprint' is not defined

以为我会尝试在命令行中"pip install pprint",但这也不起作用:

PS C:\Python34> pip install pprint
Collecting pprint
Could not find a version that satisfies the requirement pprint (from versions: )
No matching distribution found for pprint 

我认为Python 3.4.3应该带有pprint模块.我如何让它工作？似乎无法导入pprint,但所有其他模块都工作正常.我需要pprint模块来完成Automate The Boring Stuff with Python的一些练习.谢谢你看我的问题.

我正在尝试创建一个将表单输入保存为URL查询的表单.但是,当我按下表单的提交按钮时,我不知道为什么会发生这种情况.我确定它与redirect()或我的表单有关.

app = Flask(__name__)
