There is something wrong with the indentation,

CodePudding user response:

Hello, I put the indentation in the format you give advance, but still can't run

CodePudding user response:

Code that defines the three functions, you want to do what?

CodePudding user response:

Regular expressions are correct, but the program doesn't run
Indeed, your code regular (perhaps) is right
And you say can't run, in fact, has been running for
- "already according to your Python code to run the
- "run the result: nothing dry
- "why didn't do, because you didn't write code to make it work
- specific said: "you only defines the three functions (which is a function of regular) as you say, but they didn't call (any one)
So into you said: "code cannot run
"
How to let it run?
Such as code then add

 
PageHtml=get_one_page (url) 
RespGenerator=parse_one_page (pageHtml) 
For eachItemDict respGenerator in: 
Write_to_file (eachItemDict)

Can be achieved:
Really calling function performs the internal code and logic - "really run into said: you want code,

In addition, the indentation of code you code to run but I can't run, you thought see:
[tutorial], a Python code indentation (Indent) : the internal logic relationship affect code and results - in the way
