需要创建一个程序,打印出一个特定的字母开始的单词 [英] Need to create a program that prints out words starting with a particular letter
问题描述
我需要一个程序,要求用户输入3个字母,然后询问用户一个字符串,然后打印出以三个字母开头的字符串中的所有单词...例如
输入3个字母:AMD
输入文字:Advanced Micro Devices是所有微软桌面的品牌
word:Advanced Micro Devices
word :所有微软桌面
非常简单。我是新来的,无法弄清楚...我的代码目前是什么...
ipt1 = raw_input(Three字母:)##询问三个字母
ipt2 = raw_input(Text:)##询问文本
ipt1_split = ipt1.split()##将三个字母转换成列表
ipt2_split = ipt2.split()##将文本转换为列表
我不确定是否需要一个列表或不,任何人都知道如何解决这个问题?
我会做这样的事情:
<$ p $ b $ = $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b words_lc = [x.lower()for x in word] #lowercase copy不区分大小写的检查
for x in range(len(words) - n + 1):
如果所有((words_lc [x + n] .startswith(letters [n])为范围(n)中的n)):
printmatch:,''.join(words [x:x + n ])
在这种情况下,字母的数量是动态的,如果你想把它固定为3 n
为三。如果要匹配字母大小写,请删除raw_input上的下
调用以及 all
中的比较。 / p>
I need a program that asks the user for 3 letters then asks the user for a string, then prints out all words in the string that start with the three letters...e.g
Enter 3 letters: AMD
Enter text: Advanced Micro Devices is a brand for all microsoft desktops
word: Advanced Micro Devices
word: all microsoft desktops
it's pretty simple. I'm new and having trouble figuring out how...my code is currently...
ipt1 = raw_input("Three letters: ") ## Asks for three letters
ipt2 = raw_input("Text: ") ## Asks for text
ipt1_split = ipt1.split() ## Converts three letters to list
ipt2_split = ipt2.split() ## Converts text to list
I'm not sure if you need a list or not, anyone know how to tackle this problem? Thanks!
I'd do something like this:
letters = raw_input("letters: ").lower()
n = len(letters)
words = raw_input("text: ").split()
words_lc = [x.lower() for x in words] #lowercase copy for case-insensitive check
for x in range(len(words) - n + 1):
if all((words_lc[x+n].startswith(letters[n]) for n in range(n))):
print "match: ", ' '.join(words[x:x+n])
In this case the number of letters is dynamic, if you want it fixed to three just set n
to three. If you want to match case of the letters, remove the lower
calls on the raw_input and the comparison in all
.
