Python pprint and pythonpprint

Python pprint and pythonpprint

1. Background

Pprint is mentioned here.
I'm going to try it.

2. Introduction to pprint

Find the explanation on the official online website:

Pprint-Data pretty printer

It is a good thing for you to easily print some relatively complex variables.

3. Use pprint

Try writing some code.

Code:
Copy codeThe Code is as follows:
#-------------------------------------------------------------------------------
# Name: [Record] pprint in Python

#-------------------------------------------------------------------------------

Import pprint;
Import re;

Def pprintDemo ():
VarsList = [
[1, 2, 3],
["AB", "c", "def"],
Re. compile ("\ w + "),
("123", "abc "),
{
"Key1": "value1 ",
"Key2": "value2 ",
},
];

For value in varsList:
Print value;

Print "-" * 80;

Pp = pprint. PrettyPrinter (indent = 4 );
For value in varsList:
Pp. pprint (value );

Print "=" * 80;
Stuff = ['spam', 'egg', 'lumberjack', 'knights ', 'ni'];
Stuff. insert (0, stuff [:]);
Print stuff;
Print "-" * 80;
Pp. pprint (stuff)

If _ name _ = '_ main __':
PprintDemo ();

Effect:

Copy codeThe Code is as follows:
[1, 2, 3]
['AB', 'C', 'def ']
<_ Sre. SRE_Pattern object at 0x00000000030DD378>
('20140901', 'abc ')
{'Key2': 'value2', 'key1': 'value1 '}
--------------------------------------------------------------------------------
[1, 2, 3]
['AB', 'C', 'def ']
<_ Sre. SRE_Pattern object at 0x00000000030DD378>
('20140901', 'abc ')
{'Key1': 'value1', 'key2': 'value2 '}
========================================================== ==========================================================
[['Spam', 'egg', 'lumberjack', 'knights ', 'ni'], 'spam', 'eggs', 'lumberjack', 'knights ', 'ni']
--------------------------------------------------------------------------------
[['Spam', 'egg', 'lumberjack', 'knights ', 'ni'],
'Spam ',
'Eggs ',
'Lumberjack ',
'Knights ',
'Ni']

4. Summary

Pprint.

It can be used in code debugging later.
