下次请把你遇到的一些代码和遇到的问题贴出来。

def initials(phrase):
    return ''.join(word[0].upper() for word in phrase.split())


print(initials('Universal Serial Bus'))
print(initials('local area network'))
print(initials('Operating system'))

Answer 2

def initials(phrase):
    words = phrase.split()                #splits given data into list  
    result = ""
    for word in words:                    #iterates word in 'words'
        result += word[0].upper()         #stores 1st letter in Uppercase
    return result

print(initials("Universal Serial Bus")) # Should be: USB
print(initials("local area network")) # Should be: LAN
print(initials("Operating system")) # Should be: OS
