Dictionary traversal memo in Python and python dictionary memo

Dictionary traversal memo in Python and python dictionary memo

I have forgotten how to traverse the dictionary in python. There is not much technical content. It is only for my reference as a beginner.

Copy codeThe Code is as follows:
#! /Usr/bin/env python
# Coding = UTF-8
DemoDict = {'1': 'chromi', '2': 'android '}

For key in demoDict. keys ():
Print key

For value in demoDict. values ():
Print value

For key in demoDict:
Print key, demoDict [key]

For key, value in demoDict. items ():
Print key, value

For key in demoDict. iterkeys ():
Print key

For value in demoDict. itervalues ():
Print value

For key, value in demoDict. iteritems ():
Print key, value

Print 'dict. keys () = ', demoDict. keys (),'; dict. iterkeys () = ', demoDict. iterkeys ()

Interitems and iterms
