在该程序中,给出了两个字典。我们的任务是合并这两个列表。这里我们使用update()方法。更新方法可以用于合并两个列表。在这里,第二个列表合并到第一个列表中。它不返回任何值,表示不创建任何新列表。
Input:: A= ['AAA',10] B= ['BBB',20] Output:: C= {'BBB': 20, 'AAA': 10}
Step 1: First create two User input dictionary. Step 2: then use update() for merging. The second list is merged into the first list Step 3: Display the final dictionary.
def Merge(dict1, dict2): return(dict2.update(dict1)) # Driver code d1 = dict()d2=dict() data = input('Enter Name & Roll separated by ":" ') temp = data.split(':') d1[temp[0]] = int(temp[1]) for key, value in d1.items(): print('Name: {}, Roll: {}'.format(key, value)) data = input('Enter Name & Roll separated by ":" ') temp = data.split(':') d2[temp[0]] = int(temp[1]) for key, value in d2.items(): print('Name: {}, Roll: {}'.format(key, value)) # This return None (Merge(d1, d2)) print("Dictionary after merging ::>",d2)
输出结果
Enter Name & Roll separated by ":" AAA:10 Name: AAA, Roll: 10 Enter Name & Roll separated by ":" BBB:20 Name: BBB, Roll: 20 Dictionary after merging ::> {'BBB': 20, 'AAA': 10}
