Question

好的，我正在试图弄清楚如何在python中创建一个像这样的输入短语....

Self contained underwater breathing apparatus

输出这个......

SCUBA

这是每个单词的第一个字母。这与索引有关吗？也许是.upper函数？

Answer 1

这是pythonic的方法：

output = "".join(item[0].upper() for item in input.split())
# SCUBA

你去吧。简短易懂。

<强> LE ：如果你有其他分隔符而不是空格，你可以用文字分割，如下所示：

import re
input = "self-contained underwater breathing apparatus"
output = "".join(item[0].upper() for item in re.findall("\w+", input))
# SCUBA

Answer 2

这是完成任务的最快捷方式

input = "Self contained underwater breathing apparatus"
output = ""
for i in input.upper().split():
    output += i[0]

Answer 3

#here is my trial, brief and potent!
str = 'Self contained underwater breathing apparatus'
reduce(lambda x,y: x+y[0].upper(),str.split(),'')
#=> SCUBA

Answer 4

Pythonic Idioms

在str.split（）
通过将upper（）移动到循环外部的一个调用来优化内部循环。

<强>实施

input = 'Self contained underwater breathing apparatus'
output = ''.join(word[0] for word in input.split()).upper()

Answer 5

另一种方式

input = 'Self contained underwater breathing apparatus'

output = ''.join(item[0].capitalize() for item in input.split())

Answer 6

def myfunction(string):
    return (''.join(map(str, [s[0] for s in string.upper().split()])))

myfunction("Self contained underwater breathing apparatus")

返回SCUBA

Answer 7

s = "Self contained underwater breathing apparatus" 
for item in s.split():
    print item[0].upper()

Answer 8

一些列表理解爱：

 "".join([word[0].upper() for word in sentence.split()])

Answer 9

另一种可能让初学者更容易理解的方式：

acronym = input('Please give what names you want acronymized: ')
acro = acronym.split() #acro is now a list of each word
for word in acro:
    print(word[0].upper(),end='') #prints out the acronym, end='' is for obstructing capitalized word to be stacked one below the other
print() #gives a line between answer and next command line's return

Answer 10

我相信你也可以通过这种方式完成它。

def get_first_letters(s):
    return ''.join(map(lambda x:x[0].upper(),s.split()))

短语中每个单词的大写首字母
