![]() A less intrusive command is the keyword continue, which skips the remaining code in the current iteration of the for-loop, and continues on to the next element of the looping array. Break statements are used when anything happens in a for-loop that would make you want it to stop early. Similarly, if a human was given the same task for a long string of characters, that person would not continue looking for digits if he or she already found one. 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. Check the description of the function range and get familiar with how to use it.
