如何提取某些單詞的第一個字母

Question

我有一項作業要我為輸入字符串命名“昵稱”。 到目前為止，我能夠提取字符串中每個單詞的第一個字母，但我需要排除代詞和小於三個字符的單詞。

這是我到目前為止：

def nickname():
    name = input('Would you like to nickname a sentence or would you like to quit?: ')
    if name == "quit":
        print("bye")
    words = name.split()
    letters = [word[0] for word in words]
    return(" ".join(letters).upper())

Answer 1

嘗試

def nickname():
    name = input('Would you like to nickname a sentence or would you like to quit?: ')
    if name == "quit":
        print("bye")
    words = name.split()
    letters = [word for word in words if len(word)>3]
    return(" ".join(letters).upper())

Answer 2

def nickname():
    name = input('Would you like to nickname a sentence or would you like to quit?:   ') 
    if name == "quit":
        print("bye")
    else:
      words = name.split()
      letters = [word[0] for word in words if len(word)>3]
      return("".join(letters).upper())

print(nickname())
