使用 while 循环从字符串中一次打印一个字符 [英] Printing one character at a time from a string, using the while loop

问题描述

我正在阅读Core Python Programming 2nd Edition"，他们要求我使用while"循环打印一个字符串，一次一个字符.

Im reading "Core Python Programming 2nd Edition", They ask me to print a string, one character at a time using a "while" loop.

我知道 while 循环是如何工作的，但由于某种原因，我无法想出如何做到这一点.我一直在环顾四周，只看到使用 for 循环的示例.

I know how the while loop works, but for some reason i can not come up with an idea how to do this. I've been looking around, and only see examples using for loops.

所以我必须做的:

用户提供输入:

text = raw_input("Give some input:  ")

我知道如何从数组中读出每条数据，但我不记得如何对字符串执行此操作.

I know how to read out each piece of data from an array, but i can't remember anything how to do it to a string.

现在我需要做的就是工作 while 循环，它打印字符串的每个字符，一次一个.

Now all i need is working while-loop, that prints every character of the string, one at a time.

我想我必须使用 len(text)，但我不是 100% 确定如何在这个问题中使用它.

i guess i've to use len(text), but i'm not 100% sure how to use it in this problem.

一些帮助会很棒！我确定这是一个非常简单的问题，但由于某种原因我无法想出它！

Some help would be awsome! I'm sure this is a very simple issue, but for some reason i cannot come up with it!

提前谢谢！:)

推荐答案

我很确定，互联网上到处都是 Python 的 while 循环，但举个例子:

I'm quite sure, that the internet is full of python while-loops, but one example:

i=0

while i < len(text):
    print text[i]
    i += 1
