1. Python dictionary's clear() method (removes all elements from the dictionary)
#!/usr/bin/python
# -*- coding: UTF-8 -*-
dict = {'name': 'My blog address', 'alexa': 10000, 'url': '/uuihoo/'}
(); # Clear all dictionary entries
2. The pop() method of a Python dictionary (removes the value corresponding to a given key of the dictionary; the return value is the value that was removed)
#!/usr/bin/python
# -*- coding: UTF-8 -*-
site= {'name': 'My blog address', 'alexa': 10000, 'url':'/uuihoo/'}
pop_obj=('name') # Delete the key-value pair to be deleted, e.g., the key-value pair {'name':'my blog address'}
print pop_obj # exports ：My blog address
3. The popitem() method for Python dictionaries (returns and removes a random pair of keys and values from a dictionary)
#!/usr/bin/python
# -*- coding: UTF-8 -*-
site= {'name': 'My blog address', 'alexa': 10000, 'url':'/uuihoo/'}
pop_obj=() # Randomly return and delete a key-value pair
print pop_obj # The output may be{'url','/uuihoo/'}
4. del global method (can delete a single element can also empty the dictionary, empty only one operation)
#!/usr/bin/python
# -*- coding: UTF-8 -*-
site= {'name': 'My blog address', 'alexa': 10000, 'url':'/uuihoo/'}
del site['name'] # Delete entry with key 'name'
del site # Clear all dictionary entries
