输出用户输入的每个单词的第一个字母

Question

I have this code

#Ask for word
w = input("Type in a word to create acronym with spaces between the words:")

#Seperate the words to create acronym
s = w.split(" ")
letter = s[0]

#print answer 
print(s.upper(letter))

And I know that I need a for loop to loop over the words to get the first letter of each word but I can't figure out how to do it I tried many different types but I kept getting errors.

Answer 1

Try this. It prints a concatenated version of the first letter of each word.

w = input("Type in a word to create acronym with spaces between the words:")
print(''.join([e[0] for e in w.split()]).upper())

Answer 2

Try this

w = input("Type a phrase with a space between the words:")
w_up_split = w.upper().split()
acronym = ""

for i in w_up_split:
    acronym += (i[0])
print(acronym)

Answer 3

for word in w.split(" "):
    first_letter = word[0]
    print(first_letter.upper())

Answer 4

In the code that you gave you are taking the first word in a list of lists.

s = w.split(" ")
letter = s[0]

If someone input 'Hi how are you' this s would equal

s == ["Hi"]["how"]["are"]["you"]

And then letter would equal the first index of s which would be ["Hi"]

You want to go through each word and take each letter

acronym = []
for x in s:
    acronym.append(x[0])

Would get what you want.
