Thebreak statementis used inside the loop to exit out of the loop. If thebreak statementis used inside a nested loop (loop inside another loop), it willterminate the innermost loop. In the following example, we have two loops. The outerforloop iterates the first four numbers using therange...

When programming in Python,forloops often make use of therange()sequence type as its parameters for iteration. Break statement with for loop The break statement is used to exit the for loop prematurely. It’s used to break the for loop when a specific condition is met. Let’s say we hav...
Here’s a breakdown of what’s happening in the code:Line 4 loops over each filename provided by the user. The sys.argv list contains each argument given on the command line, starting with the name of your script. For more information about sys.argv, you can check out Python Command ...
nested loops When there are one or more loops “inside” of another loop. The inner loop runs to completion each time the outer loop runs once. value An object that appears in a dictionary as the second part of a key-value pair. This is more specific than our previous use of the word...
Also the topic of nested loops After, you'll see how you can use the break and continue keywords. The difference between the xrange() and range() functions While Loop The while loop is one of the first loops that you'll probably encounter when you're starting to learn how to program...
Two basic loop types are for loops and while loops. For loops iterate through a list and while loops run until a condition is met or until we break out of the loop. We used a for loop in earlier scripts (e.g., pass.py), but we haven't seen a while loop yet:...
When a return, break or continue statement is executed in the try suite of a "try…finally" statement, the finally clause is also executed on the way out. The return value of a function is determined by the last return statement executed. Since the finally clause always executes, a return...
RapydScript implements do/while loops via similar syntax as well:a = 0 do: print(a) a += 1 .while a < 1 Function calling with optional argumentsRapydScript supports the same function calling format as Python. You can have named optional arguments, create functions with variable numbers of ...
