Python 字典(Dictionary) items()方法

Python 字典(Dictionary) items() 函数以列表返回可遍历的(键, 值) 元组数组。

Example #1:

 

# Python program to show working

# of items() method in Dictionary

  

# Dictionary with three items 

Dictionary1 = { 'A': 'Geeks', 'B': 4, 'C': 'Geeks' }

  

print("Dictionary items:")

  

# Printing all the items of the Dictionary

print(Dictionary1.items())

Output:

Dictionary items:
dict_items([('C', 'Geeks'), ('B', 4), ('A', 'Geeks')])

Order of these items in the list may not always be same.
 
Example #2: To show working of items() after modification of Dictionary.

# Python program to show working

# of items() method in Dictionary

  

# Dictionary with three items 

Dictionary1 = { 'A': 'Geeks', 'B': 4, 'C': 'Geeks' }

  

print("Original Dictionary items:")

  

items = Dictionary1.items()

  

# Printing all the items of the Dictionary

print(items)

  

# Delete an item from dictionary

del[Dictionary1['C']]

print('Updated Dictionary:')

print(items)

Output:

Original Dictionary items:
dict_items([('A', 'Geeks'), ('C', 'Geeks'), ('B', 4)])
Updated Dictionary:
dict_items([('A', 'Geeks'), ('B', 4)])

If the Dictionary is updated anytime, the changes are reflected in the view object automatically.
