Assignment expressions allow you to assign the result of an expression used in a conditional or a while loop to a name in one step. For example, consider the following loop that takes input from the keyboard until you type the word "stop":...
You use this same name in the C++ code when you define the module for Python. To use the name of the project as the module name, leave the default value of $<ProjectName>. For python_d.exe, add _d to the end of the name. Configuration Type Dynamic Library (.dll) Configuration ...

Core Data Types in Python As the name suggests, a data type is the classification of the type of values that can be assigned to variables. We have already seen that, here in Python, we don’t need to declare a variable with explicitly mentioning the data type, but it’s still important...
It is not necessary to define the loop variable beforehand. Python creates this variable when it is first used. The keyword in. A sequence to constrain how many times the loop executes. This is supplied using either the range function or a sequential data object. The built-in range function...

;; This code adds up to 10000 from 0 via calling a function that takes a variable number of arguments. ;; That function then reduces over the argument list to add up all given arguments. (defn add-fn [& args] (reduce -add 0 args)) (loop [x 0] (if (eq x 10000) x (recur (...
Then you use globals() to create a global variable using key as the variable name and value as its value.In the with statement, you open the configuration file for reading and assign the file object to the json_config variable. Then you use a for loop to process the loaded configuration...
