Code can be repeated using a loop. Lines of code can be repeated N times, where N is manually configurable. In practice, it means code will be repeated until a condition is met. This condition is usually x >=N but it’s not the only possible condition. Below please find links to archived Q&A discussion for the Python Syntax course. Depends.

A loop statement allows us to execute a statement or group of statements multiple times. The following diagram illustrates a loop statement − The following diagram illustrates a loop statement − Python programming language provides following types of loops to handle looping requirements. If during the execution of the loop Python interpreter encounters break, it immediately stops the loop execution and exits out of it. In this case, the else: branch is not executed. So, break is used to abort the loop execution during the middle of any iteration.
That means that if you want to loop the next five lines with a 'while' loop, you must put a set number of spaces at the beginning of each of the next five lines. This is good programming practice in any language, but python requires that you do it. Here is an example of both of the above points. Python supplies two different kinds of loops: the while loop and the for loop, which correspond to the condition-controlled loop and collection-controlled loop. Most loops contain a counter or more generally variables, which change their values in the course of calculation. Codecademy. Python programming language Programming Languages. Computer Programming.

Global Variables In Python, a variable declared outside of the function or in global scope is known as global variable. Python is capable of threading and GPU processing just like any other language. Most of the data processing modules are actually just Python wrappers around C/C code. "Modules" are pre-written Python code that you "import" in your Python program.
