Literals are notations forconstant valuesof some built-in types. 字面量 是一些内置类型的常量值的记法。 python中literals 有6种,字符串字面量,字节字面量,数字字面量,整型字面量,浮点字面量,虚部字面量 字符串字面量(string literals) var = 'I am string literal.' # 如果两个string literal相邻的...
Consider the below example, where (\) doesn't have special meaning, s='Hi\xHello' Output The output of the above example is: File "main.py", line 1 s='Hi\xHello' ^ SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \xXX escape...
importstd.stdio;intmain(string[]args){writeln(q"MY_DELIMITER Hello World Have a good day MY_DELIMITER");writefln("Have a good day%c",'\x21');autostr=q{int value = 20; ++value;};writeln(str);} In the above example, you can find the use of q"MY_DELIMITER MY_DELIMITER" to repre...
"', but that doesn't really solve the problem. Instead, you can escape any quote character inside the string, and it will lose its special meaning (in this case, the special meaning is to close the string). To escape a character, prepend it with the backslash character. The backslash c...
The value of a raw string literal is the string composed of the uninterpreted (implicitly UTF-8-encoded) characters; in particular, backslashes have no special meaning. Interpreted string literals are character sequences between double quotes, as in "bar" where the bar could be anything except ...
stdintmain(){constintLENGTH=10;constintWIDTH=5;constcharNEWLINE='\n';intarea;area=LENGTH*WIDTH;cout<<area;cout<<NEWLINE;return0;} When the above code is compiled and executed, it produces the following result − 50 Note that it is a good programming practice to define constants in CAPI...
