Question

我收到了学校的作业，我必须创建一个函数，该函数接收一个字符串，并将字符串中每个单词的第一个字母的连接作为首字母缩写词返回。返回应该类似于 " the first letter in word number {counter} is {letter}"，其中 {counter} 是单词在给定字符串中的位置，{letter} 是单词的第一个字母。最后，我必须连接以下格式 " the Acronym for the text given is {acronym}"，其中 {acronym} 是文本的首字母缩写词，它是文本中给出的每个单词的第一个字母的连接。

这是我目前所做的：

def Acronym_Creator(text:str()):

   text= 'Hello World I Need Help'
   if text != '':
       for word in range(len(text.split())):
          Counter=0
          Counter= Counter+word+1
          print (  'The first letter  in  word number {Counter} is ')

到目前为止，这只是用于计算单词在给定文本中的位置。我不知道如何连接属于该位置的单词，以便我可以继续然后创建首字母缩写词。

Answer 1

这里：

def acronym(string):
    str_lst = string.split()
    acronym = ""
    for i in str_lst: # go through all the string elements in our list
        acronym += i[0].capitalize() # add the character as 0th position in that string, also you might want to capitalize that letter(if not already). 
    return acronym

String = "Hello World I Need Help"
print(acronym(String))

Answer 2

试试这个：

def acronym(text):
    words = text.split(' ')
    acro = ''
    for i in range(len(words)):
        print('The first letter in  word number {} is {}'.format(i+1, words[i]))
        acro += words[i][0].upper()

    print('The acronym is {}'.format(acro))


text = 'Hello World this is some text input'
acronym(text)

输出是

The first letter in  word number 1 is Hello
The first letter in  word number 2 is world
The first letter in  word number 3 is this
The first letter in  word number 4 is is
The first letter in  word number 5 is some
The first letter in  word number 6 is text
The first letter in  word number 7 is input
The acronym is HWTISTI

Answer 3

我将为此使用正则表达式库。

有效词的识别：

\b - 匹配单词开头或结尾的空字符串
() - 是您要查找的组
[A-Za-z] - 仅字母，忽略以无效字符开头的表达式，例如数字
\w - 匹配 a-z 或数字
* - 零次或多次出现

import re


def acronymizer(string: str):
    words = re.findall(pattern=r'\b([A-Za-z]{1}\w*)', string=string)
    [print(f"The First letter in {w} is {w[0]}") for w in words]
    acronym = ''.join([w[0].upper() for w in words])
    print(f"acronym is: {acronym}")
    return acronym


String = "Hello World I Need Help !"
print(acronymizer(String))

从字符串创建首字母缩略词的函数
