In this paper, we describe the method of implementing two dictionaries (dict) merging in Python, and share them for your reference. Here's how: The existing two dictionaries are dict as follows: DICT1={1:[1,11,111],2:[2,22,222]}DICT2={3:[3,33,333],4:[4,44,444]} Merge two dictionaries to get a similar: {1:[1,11,111],2:[2,22,222],3:[3,33,333],4:[4,44,444]} Method 1: Dictmerged1=dict (Dict1.items () +dict2.items ()) Method 2: Dictmerged2=dict (Dict1, **dict2) Method 2 is equivalent to: Dictmer

OSX and most Linux distributions have built-in Python, Perl, Ruby and other programming language environments. it is a good thing for developers and common users. developers have many choices when writing programs, there is no need to worry about finding a replacement for the language environment on the target machine, and the user can run it directly. O M personnel can also worry a lot during large-scale deployment of some scripts. Why does Microsoft not do this? Are you afraid of threatening

called "inline function", that is, although the function is written, but compile it as a part of the caller directly compiled into the function, and the normal function is to return to jump (such as assembly instructions RET, JMP). So, in this case, the two magic constants will draw the value we want as expected. However, there is no inline function in PHP, and there is no inline keyword ...Two or one technology is not a skill, there is a thing to do "macro definition." C language is often used
