for (const key in arr) { console.log(key) } // 0,1,2,3,4 使用for...in可以遍历数组,但是会存在以下问题: index 索引为字符串型数字(注意,非数字),不能直接进行几何运算。 遍历顺序有可能不是按照实际数组的内部顺序(可能按照随机顺序)。 所以一般不建议使用for...in来遍历数组。 for...of for....
In this example, we look for the longest string found within a file. When given one ormore filenames on the command line, this program uses the strings program (which isincluded in the GNU binutils package) to generate a list of readable text “words” in eachfile. The for loop process...

Even strings are iterable objects, they contain a sequence of characters: Example Loop through the letters in the word "banana": forxin"banana": print(x) Try it Yourself » The break Statement With thebreakstatement we can stop the loop before it has looped through all the items: ...
Let’s implement a one-lineforloop to iterate over Python iterable objects. In this example, I will take the list of strings as an iterable object. # Write For loop in one line # to iterate through a list # Initialize the list
In Python, the for loop operates on objects known as “iterables”. This includes strings, lists, tuples and other collections of data. In the words of the official Python documentation: Quote “[An iterable is] an object capable of returning its members one at a time” — Source: http...
1.Strings:In Python, strings are iterable. Each iteration through a string accesses one character at a time. for char in "Hello": print(char) 2.Lists: Lists in Python are ordered, mutable collections of items. They can contain elements of different types, including other lists. Loops are ...
In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e
Using a for…in Loop with Strings You can loop over a string with the JavaScriptfor...inloop. However, it’s not recommended to do so, as you’ll be looping over the indices of the characters rather than the characters themselves. ...
