#ONE LINE FOR LOOP PYTHON CODE#
The code will still function properly without this statement, but since the task is to find out if there are any digit in s, we do not have to keep looking if we find one.
In this particular case, the break command is executed if we ever find a digit in the string. If executed, the break keyword immediately stops the most immediate for-loop that contains it that is, if it is contained in a nested for-loop, then it will only stop the innermost for-loop. The first step in the function have_digits assumes that there are no digits in the string s (i.e., the output is 0 or False). Other examples of sequences that we can iterate over include the elements of a tuple, the characters in a string, and other sequential data types.ĮXAMPLE: Print all the characters in the string "banana". We present several more examples to give you a sense of how for-loops work. With no more values to assign in the list, the for-loop is terminated with The variable n is assigned the value n + i ( \(3 + 3 = 6\)). The variable n is assigned the value n + i ( \(1 + 2 = 3\)). The variable n is assigned the value n + i ( \(0 + 1 = 1\)). In a very simple form, it is range(start, stop, step), and the step is optional with 1 as the default.

This tutorial taught us two different methods, list comprehension and exec(), that can be used to nest for loops in one line.Python Programming And Numerical Methods: A Guide For Engineers And ScientistsĬhapter 2. # pythonĮxec("for a in listOne:\n for b in listTwo:\n print(a+b)")Īs you can see from the example, using the exec() function, we added 2 different lists using nested for loop in one line. Let’s go through an example in which we will add two lists and print the sum as shown below.
It is used for the dynamic execution of a Python program that can be a string or an object code. Now, we will discuss another function that can help us achieve a nested for loop in one line, the exec() function. Nested for Loop in One Line Using the exec() Function in Python # pythonįrom the example, we have added 2 different lists using the nested for loop in one line using list comprehension. First of all, we will create two lists, listOne and listTwo, and then use them to print the result as shown below. Let’s go through an example and use list comprehension. There are three methods in which we can easily write a nested for loop in one line. Nested for Loop in One Line Using List Comprehension in Python This tutorial will discuss some different methods that can be used to write a nested for loop in just one line. In Python, we write the for loop in one line, but how can we write it in one line when we have to use another loop inside it?
The for loop is one of the most commonly used loops to iterate items from a list. Nested for Loop in One Line Using the exec() Function in Python.Nested for Loop in One Line Using List Comprehension in Python.
