Python |通过键相交两个字典
原文:https://www . geesforgeks . org/python-intersect-two-dictionary-through-keys/
给定两个字典，任务是通过键找到这两个字典的交集。让我们看看完成这项任务的不同方法。
方法一:使用字典理解
# Python code to demonstrate
# intersection of two dictionaries
# using dict comprehension
# inititialising dictionary
ini_dict1 = {'nikhil': 1, 'vashu' : 5,
'manjeet' : 10, 'akshat' : 15}
ini_dict2 = {'akshat' :15, 'nikhil' : 1, 'me' : 56}
# printing initial json
print ("initial 1st dictionary", ini_dict1)
print ("initial 2nd dictionary", ini_dict2)
# intersecting two dictionaries
final_dict = {x:ini_dict1[x] for x in ini_dict1
if x in ini_dict2}
# printing final result
print ("final dictionary", str(final_dict))
Output:
初始第一字典{'vashu': 5，' manjeet': 10，' nikhil': 1，' akshat': 15} 初始第二字典{'nikhil': 1，' me': 56，' akshat': 15} 最终字典{'nikhil': 1，' akshat': 15}
方法 2:使用& operator
# Python code to demonstrate
# intersection of two dictionaries
# using dict comprehension
# inititialising dictionary
ini_dict1 = {'nikhil': 1, 'vashu' : 5,
'manjeet' : 10, 'akshat' : 15}
ini_dict2 = {'akshat' :15, 'nikhil' : 1, 'me' : 56}
# printing initial json
print ("initial 1st dictionary", ini_dict1)
print ("initial 2nd dictionary", ini_dict2)
# intersecting two dictionaries
final_dict = dict(ini_dict1.items() & ini_dict2.items())
# printing final result
print ("final dictionary", str(final_dict))
Output:
初始第一字典{'vashu': 5，' manjeet': 10，' nikhil': 1，' akshat': 15} 初始第二字典{'nikhil': 1，' akshat': 15，' me': 56} 最终字典{'nikhil': 1，' akshat': 15}
