我在我的猪拉丁语翻译器中犯了什么错误

Question

1. if a word begins with a vowel the word 'yay' is added at the end of the word.

2. if the word begin with a cosonant or consonant cluster, that consonant or consonant cluster is moved to the end the word followed by 'ay'.

    def vowel(value): value=str(value) vowels=['a','e','i','o','u','A','E','I','O','U'] if value[0]in vowels: value=value+'yay' return(value) def consonant(value): value=str(value) vowels=['a','e','i','o','u','A','E','I','O','U'] b=0 for i in range(len(value)): if a[i] in vowels: b=i break c=a[b:len(a)]+a[0:b]+'ay' return(c) spam='My name is AL SWEIGART and i am 4000 years old.' spam1=spam.split() a=['a','e','i','o','u','A','E','I','O','U'] for i in range(len(spam1)): if spam1[i][0] in a: spam1.insert(vowels(spam1[i]),i) else: spam1.insert(consonant(spam1[i]),i) print(spam1)

3. TypeError Traceback (most recent call last) in 22 spam1.insert(vowels(spam1[i]),i) 23 else: ---> 24 spam1.insert(consonant(spam1[i]),i) 25 print(spam1)

   in consonant(value) 13 b=i 14 break ---> 15 c=a[b:len(a)]+a[0:b]+'ay' 16 return(c) 17 spam='My name is AL SWEIGART and i am 4000 years old.'

TypeError: can only concatenate list (not "str") to list

Answer 1

First thing first it seems that you mixed up value with a in the consonant() function, and since you refer to a[b:len(a)] when declaring c , it seems that Python refers to the a variable which happens to be a list instead of string ( ['a','e','i','o','u','A','E','I','O','U'] )

In this specific line of code,

c=a[b:len(a)]+a[0:b]+'ay'

c is declared as a list instead of string containing every item inside list a ranging from b to len(a) . The result is then concatenated with a[0:b] which returns another list, but then you concatenate it with 'ay' which happens to be a string instead of list. Hence, the TypeError you've mentioned in the question.

The solution itself might be trivial, just change that specific line and the preceeding if statement into

    if value[i] in vowels:
       b=i
       break
    c=value[b:len(value)]+value[0:b]+'ay'

Hope this works!
