Python for loop with string The following example uses Pythonforstatement to go through a string. for_loop_string.py #!/usr/bin/python word = "cloud" for let in word: print(let) We have a string defined. With theforloop, we print the letters of the word one by one to the terminal...
Fixed number of times: Print the multiplication table of 2. In this case, you know how many iterations you need. Here you need 10 iterations. In such a case use for loop. for loop in Python Syntax of for loop for i in range/sequencee: statement 1 statement 2 statement n In the syn...
Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了for循环是什么?) A for-loop has two parts: a header specifying the iteration, and a body which is executed once per...
在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is acontrol flowstatementfor specifyingiteration, which allows code to beexecutedrepeatedly。(作用:介绍了f...
for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。 for语句其实是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: In computer science, afor-loop(or simplyfor loop) is a control flow statement for specifying iteration, which allows...
forindexinrange(n):statement 其中，index 被称为循环计数器（loop counter），n 是循环执行的次数。
When programming in Python,forloops often make use of therange()sequence type as its parameters for iteration. Break statement with for loop The break statement is used to exit the for loop prematurely. It’s used to break the for loop when a specific condition is met. ...
for in : else: Python中for循环可以遍历任何序列的项目,如一个列表或者一个字符串。 实例1: names=["tom","jimmy","mary","jack"] for name in names: print(name.title()) #运行结果 Tom Jimmy Mary Jack 上例代码说明:title()方法的作用是,将字符串首字母转换成大写并返回该字符串。上例中for后面...
for i in "python": print(i) 1. 2. p y t h o n 1. 2. 3. 4. 5. 6. 在看另一个例子: for i in "abcdefg": print(i) 1. 2. a b c d e f g 1. 2. 3. 4. 5. 6. 7. 列表的for循环 不管是单层列表还是多层的嵌套列表,我们都可以遍历打印出来: ...
print(i) In the above code: There are two “one line for loop” used in the above code. The first “one line for loop” is applied on the range from “(1,6)”, and the print statement is used to print out all the elements in the specified range. ...
