Looping through a string to print individual characters The sections below outline a few examples of for loop use cases. Any object that can return one member of its group at a time is an iterable in Python. The program will continue to run as if there were no conditional statement at all.Įxample: Ways to use a for loop in PythonĪ for loop is a general, flexible method of iterating through an iterable object. In the context of a for loop, you can use a pass statement to disregard a conditional statement. It can be used as a placeholder for future code or when a statement is required by syntax but you don’t want anything to happen. The pass statement in Python intentionally does nothing. The control flow will continue on to the next iteration. You can use the keyword continue to end the current iteration of a for loop. Tell Python you want to create a for loop by starting the statement with for. Now that we know the syntax, let’s write one. Remember to include a colon after your for loop statement, and indent code included in the body of the loop. It can be used as a placeholder or to disregard code.įirst, let’s examine the basic structure of a for loop in Python:įor and in are both Python keywords, but you can name your iterator variable and iterable whatever you'd like. You can use the keyword continue to end a for loop’s current iteration and continue on to the next. The break command terminates the loop that contains it and redirects the program flow to the following statement. The else statement contains the block of code that will execute if the condition from the if statement is false or resolves to zero. ![]() If the condition is true, the if block of code will be executed. It dictates whether a statement should be executed or not by checking for a given condition. In other programming languages, it is used only for readability purposes.Ī tuple is an ordered set of values that is used to store multiple items in just one variable. ![]() In Python, indentation indicates a new line of code. Indentation is the space at the beginning of each line of code. In Python, continue, break, and pass are control statements that change the order of a program’s execution. Iterables are objects in Python that you can iterate over.Ĭontrol flow or program flow, is the order of execution in a program’s code. In programming, iteration is the repetition of a code or a process until a specific condition is met. An iterating function used to execute statements repeatedly.
