Day2 (string, formatted output, operator, process control), day2 OperatorI. String In Python, all characters with quotation marks are considered as strings! What are the differences between single quotes, double quotes, and multiple quotes? There is no difference between single quotes and double quotes, but in some cases, single quotes and double quotes must be used together. For example, msg = "My name is Small Nine, I'm 22 years old! '" What is the

the called function, and its size is determined by the data volume in the function definition body;(2) Protect the running status and return address of the called function;(3) passing parameters;(4) transfer control to the called function;(5) After the function is run, copy the result to the bottom of the local data block of the function;(6) restore the running status of the called function;(7) return the call function.Calling a function can be seen as a stack operation for the elements in a st

Is Operator Compare two object reference variables. Result = object1IsObject2Parameters Result Any numeric variable. Object1 Any object name. Object2 Any object name.Description IfObject1AndObject2If the same object is referencedResultIsTrueOtherwiseResultIsFalse. You can use many methods to make two variables reference the same object. InCodeMake the object referenced by A the same as the object referenced by B: Set a = B In the following

This is the permission value.2^0=1, the corresponding 2 in the number of "0001″ (here ^ I expressed as a" sub-party ", that is: 2 of 0 parties, the same below)2^1=2, the corresponding 2-in number is "0010″2^2=4, the corresponding 2-in number is "0100″2^3=8, the corresponding 2-in number is "1000″To judge a number within certain numbers, you can use the operator (the value is derived from the table above)such as: 7=4|2|1 (You can also easily understan

Xor operator Perform the logical "XOR" Operation on the two expressions. result = expression1 Xor expression2Parameters Result Any numeric variable. Expression1 Any expression. Expression2 Any expression.Description If one and only one expression isTrue, ThenResultIsTrue. However, if any expression is NullResultOrNull. If neither of the two expressions isNullIs determined according to the following table.Result: If expression1 is Expressio

In C ++, there is a special method to overload operators-type conversion Operator overloading, such:Operator type ();Type can be a basic type or a class type. /* Another example: Class cdemo

Is operator Compares two object reference variables. result = object1 Is object2 Parameters Result Any numeric variable. Object1 Any object name. Object2 Any object name. Description If both object1 and Object2 refer to the same object, result is True, otherwise result is False. You can use a number of methods to make two variables reference the same object. In the following code, the object referenced by a is the same as the object of B

Then, for the type of typeof var!== "number", an attempt is made to convert to a 32-bit shape data, which is converted to Nan if it cannot be converted into a shaping data; JS in-situ operation with a more convenient way to implement this operation, then its implementation principle can be generally understood as follows: Copy Code code as follows: var testdata=-2.9; var testresult= (typeof testdata=== "number" !isnan (testData) testdata!==infinity)? (testdata>0)-math.floor (te

1, if you want to turn on this feature, we just need to go to "settings" on the table under "All settings" open access to find "Notification bar settings", as shown in the figure: 2, and then open a new window to find "advanced", into the Advanced settings interface, as shown in the figure: 3, you will see the display operator name by default shutdown status, if you want to display in the notification bar we just open the switch can be
