将整数列表，数字字符串转换为整数列表

Question

名为 solve 的给定方法将列表 A 作为参数。

此列表包含以下类型的值：

integers (between 1 and 99, both inclusive)

numbers in form of strings (between 1 and 99, both inclusive) eg, '37', '91'

word form of numbers (between 1 and 99, both inclusive) eg, 'twenty', 'seventeen', 'forty-two'.

请注意，单词总是小写！

必须生成一个列表，其中包含所有整数形式的值，并且 return 它。该列表必须按升序排序。

例子

输入：

[1, 3, '4', '1', 'three', 'eleven', 'forty-seven', '3']

输出：

[1, 3, 4, 11, 47]

代码：

def solve(A):
    for i in A:
        if type(A[i])==int:
            return A.extend(A[i])
        elif type(A[i])==str:
            return int(A[i])

我们甚至需要使用集合来删除重复项而且它不起作用。！谁能帮忙写代码！

Answer 1

下面是我用代码注释解释的方法。

def solve(lst):
    # Dictionary of words to numbers
    NUMBERS_DIC = {'one': 1, 'two': 2, 'three': 3, 'four': 4, 'five': 5, 'six': 6, 'seven': 7, 'eight': 8, 'nine': 9, 'ten': 10, 'eleven': 11, 'twelve': 12, 'thirteen': 13, 'fourteen': 14, 'fifteen': 15, 'sixteen': 16, 'seventeen': 17, 'eighteen': 18, 'nineteen': 19, 'twenty': 20, 'thirty': 30, 'forty': 40, 'fifty': 50, 'sixty': 60, 'seventy': 70, 'eighty': 80, 'ninety': 90}
    
    # list to be returned 
    retLst = []
    for num in lst:
        # if num is an int
        if type(num)==int: # type() tells you the type of the variable
            retLst.append(num)
        # if num is a string that is numeric
        elif num.isnumeric():
            retLst.append(int(num)) # Turn to int
        # if num is a string word such as forty-seven"
        else:
            # turns "forty-seven" -> ["forty","seven"]
            word_values_lst = num.split("-")
            val = 0
            for word in word_values_lst:
                val+=NUMBERS_DIC[word] # Get value from NUMBERS_DIC
            retLst.append(val) 
            
                
    
    # Sort lst
    retLst.sort() 
    
    
    return list(set(retLst)) # removes duplicates


lst = [1, 3, '4', '1', 'three', 'eleven', 'forty-seven', '3']
retLst = solve(lst)

print(retLst)
