First, JavaScript allows us to carry out operations using the standard arithmetic operators of addition, subtraction, multiplication, and division. var theSum = 4 + 3; As you’ll have guessed, after this statement has been executed the variable theSum will contain a value of 7. We can use...

We created the program in Figure 13 (simple.py) and submitted it to the Python interpreter for execution. We can interact with the interpreter directly, typing in Python statements and expressions for immediate execution. As we saw in Figure 17, the IDLE window labeledPython Shellis where ...
In addition to the error handling described inSetting up Error Handling, there is one error that can occur when configuring the parser for schema-based validation. If the parser is not compliant with the JAXP spec, and therefore does not support XML Schema, it can throw aSAXNotRecognizedExcepti...
