For Loops using Sequential Data Types Listsand other data sequence types can also be leveraged as iteration parameters inforloops. Rather than iterating through arange(), you can define a list and iterate through that list. We’ll assign a list to a variable, and then iterate through the lis...
So, the Python for loop repeatedly executes a block of code. This is also referred to as “iteration”. Loops make it possible to repeat a process for several elements of a sequence. For loops are used in Python when the size of a sequence can be determined at program runtime. Otherwise...
The Python for loop is used when the number of iterations is known before the loop starts running. In contrast, the Python while loop repeats as long as a certain condition is true. This tutorial describes how to use both types of loops and explains how to use Python for common scenarios...
But for loops, function definitions, and module imports are also assignments (see Assignment isn't just about the equals sign). For much more on the nature of variables in Python, see Overlooked facts about variables and objects in Python. Tuple unpacking (a.k.a "multiple assignment") A ...
‘Docstring’ is the abbreviation for ‘documentation string’. Even though including a docstring in our function is optional, it is considered a good practice as it increases the readability of the code and makes it easy to understand. We use triple quotes around the string to write a ...

For a deep dive into how this operator works, check out The Walrus Operator: Python’s Assignment Expressions. Unlike regular assignments, assignment expressions do have a return value, which is why they’re expressions. So, the operator accomplishes two tasks: Returns the expression’s result ...
In Python, for-loops use the scope they exist in and leave their defined loop-variable behind. This also applies if we explicitly defined the for-loop variable in the global namespace before. In this case, it will rebind the existing variable. The differences in the output of Python 2.x...
e.g., make your numbers/strings smaller, arrays/lists shorter, your data structures contain fewer items, and your loops/functions run fewer times for Python, set breakpoints using special#breakcomments (example) Code that defines too many variables or objects ...
