these types can be used as keys in the dictionary. Enumeration members with unassociated values (see enumeration) can also be hashed by default.
Dictionary literal statement
We can use dictionary literal statements to construct a dictionary. They have similar syntax as the array literal statements we just introduced. A dictionary literal statement is a simple statement that defines a dictionary set with one or more key-value pairs.
A key-value pair is a combination of a key and a value. In a

Now, assuming that XYZ's wealth has increased, it is decided to introduce a new model, Model C. Model C is different from model A and model B in some aspects. In particular, its flight is different.
Programmers at XYZ added the class of Model C to hierarchy (inheritance system), but they forgot to redefine the fly function as they rushed to put new models into service:
Class modelc: Public airplane {
... // No Fly function is declared};
Therefore, in

Everyone seems to be very concerned about weather forecasts. Of course, obtaining accurate weather forecasts is very useful for your travel plans and other activities. Weather forecast information can be obtained in many places, such as webpages, most smartphones or tablets. Now you can use the "wether" tool on Raspberry Pi to obtain the weather forecast information through command line."Weather" can be installed from Raspberry Pi's official sources:
Sudo apt-get install weather-util

-value pair is a combination of a key and a value. In the dictionary literal, the keys and values in each pair of key-value pairs are separated by a colon, and the key-value pairs are separated by commas, and these key-value pairs are wrapped with a pair of parentheses:[Key 1:value 1, key 2:value 2, key 3:value 3]The following example creates a dictionary that stores the name of an international airport, in which the key is the three-letter IATA code,

to that of loop playback without gaps. First, create an interface and then load each audio file through imedia_setmediadata, call imedia_enablechannelshare () immediately after creating a media object, and then use imedia_play () for audio mixing. In versions earlier than 3.1.4, imedia_enablechannelshare () may be faulty. In addition, Apis created using aeeclsid_mediamidioutqcp can take both qcp and ADPCM files into account.
Another simple method for audio mixing is to embed all the necessary a
