如果不存在任何键,则仅返回空的Pythondict()。 Python3 test_dict = {'Gfg': {'is':'best'}}# printing original dictionaryprint("The original dictionary is : "+ str(test_dict))# using nestedget()# Safe access nested dictionary keyres = test_dict.get('Gfg', {}).get('is')# printing ...
这dict函数执行转换为字典的任务。 # Python3 code to demonstrate working of# Convert Tuples to Dictionary# Using zip() + dict()# initializing tuplestest_tup1 = ('GFG','is','best') test_tup2 = (1,2,3)# printing original tuplesprint("The original key tuple is:"+ str(test_tup1)) ...
myDict.Add( "4" , "Python" ); myDict.Add( "5" , "C#" ); myDict.Add( "6" , "HTML" ); //To get count of key/value pairs in myDict Console.WriteLine( "Total key/value pairs" + " in myDict are : " + myDict.Count); //Displaying the key/value pairs in myDict Console...
