python-3.x - 如何判断小数和日期(ex 12.4.5)

Question

我想判断文件中的单词，如果是单词，句子，整数，小数或日期（ex12.2.3）。我可以为单词、句子和整数编码，但我无法区分小数和日期。仅打印出日期，其余的与每个文件（单词，句子整数）一起归档。如何区分小数和日期？

    while True:
        word=tiedosto.readline().rstrip()
        if word=="":
            break
        elif word.isalpha():
            sana.write(word.upper()+'\n')
        elif '.' in word and ' ' in word:
            sentence.write(word.capitalize() +'\n')
        elif word.isdigit():
            luku.write(word+'\n')
            for i in word.isdigit ():
                if type(float(i)):
                    desi.write(word+'\n')
                else:
                    print("Tunnistamaton rivi '",word,"'.",sep="")  
                    
    luku.close()
