What are keywords?
Keywords in Python are reservered words that cannot be used as ordinary identifiers. They must be spelled exacty as they are written.
List of keywords
The following is a list of keywords for the Python programming language. and del from not while as elif global or with assert else if pass yield break except import print class exec in raise continue finally is return def for lambda try
This prints the keyword list of Python.
$ python >>> >>> import keyword >>> print keyword.kwlist ['and', 'as', 'assert', 'break', 'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'exec', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'not', 'or', 'pass', 'print', 'raise', 'return', 'try', 'while', 'with', 'yield']
print print to console while controlling the flow of the program for iterate over items of a collection in order that they appear break interrupt the (loop) cycle, if needed continue used to interrupt the current cycle, without jumping out of the whole cycle. New cycle will begin. if used to determine, which statements are going to be executed. elif stands for else if.If the first test evaluates to False, then it continues with the next one else is optional. The statement after the else keyword is executed, unless the condition is True is tests for object identity not negates a boolean value and all conditions in a boolean expression must be met or at least one condition must be met. import import other modules into a Python script as if we want to give a module a different alias from for importing a specific variable, class or a function from a module def used to create a new user defined function return exits the function and returns a value lambda creates a new anonymous function global access variables defined outside functions try specifies exception handlers except catches the exception and executes codes finally is always executed in the end. Used to clean up resources. raise create a user defined exception del deletes objects pass does nothing assert used for debugging purposes class used to create new user defined objects exec executes Python code dynamically yield is used with generators
