This article covers the construction and usage of While loops in Python. While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in...
A for loop implements the repeated execution of code based on a loop counter or the loop variable. For loops are used when the number of iterations is known in advance. This is the structure of a basic for loop in Python: for[Temporary variable]in[sequence]: [do something] ...
Computer programs are great to use for automating and repeating tasks so that we don’t have to. One way to repeat similar tasks is through usingloops. We’ll be covering Python’swhile loopin this tutorial. Awhileloop implements the repeated execution of code based on a givenBooleancondition...
This first creates a range corresponding to the indexes in our list (0tolen(colors) - 1). We can loop over this range using Python’s for-in loop (really aforeach). This provides us with the index of each item in ourcolorslist, which is the same way that C-styleforloops work. ...
We’re interviewing for a job and our interviewer has asked us to remove all for loops from a block of code. They then mentioned something about …

In Python, you can read a file using theopen()function. The following code example demonstrates how to read a file in Python: file = open('example.txt', 'r') data = file.read() print(data) Reading a File Line-By-Line Sometimes, you may want to read a file line-by-line. To do...
Robot does not handle if-else and nested loops, which are essential as the code becomes sophisticated. What is the purpose of For loops in Robot Framework? The for loop Robot framework is to automate repetitive tasks, reduce manual effort, and make test scripts more efficient and maintainable....
Theexec()function provides an alternative way to run your scripts from inside your code: Python >>>withopen("hello.py")ashello:...exec(hello.read())...Hello, World! In this example, you use thewithstatementto open thehello.pyfile for reading. Then, you read the file’s content with...
In this course, you'll see how you can make your loops more Pythonic if you're coming to Python from a C-style language. You'll learn how you can get the most out of using range(), xrange(), and enumerate(). You'll also see how you can avoid having to ke
