数字单词转电话号码实现问题

问题背景

我是仅学习了3个月Python的初学者，本次学校作业要求读取包含数字单词（例如：three、oh、five、nine等）的文本文件，将内容转换为电话号码后写入单独的文件中。思考许久也没想出适合初学者的简单实现代码，希望得到帮助。

梳理的IPO实现逻辑

输入：以只读模式打开文本文件
处理：将文本文件内容拆分得到单词列表，将每个单词转换为对应的数字，再把所有数字拼接为字符串
输出：将存储电话号码的字符串写入目标文件
我目前无法将上述逻辑转换为可运行的代码。

输入文件内容示例

two three seven oh nine eight oh
eight one eight four three seven two nine six three
one five oh three four seven seven two five seven two
two nine six two three five oh
five two oh four four seven nine eight two one
one eight oh oh five five five one two one two
four three seven two nine six three

最终可运行代码

di = {"oh":0,"one":1,"two":2,"three":3,"four":4,"five":5,"six":6,"seven":7,"eight":8,"nine":9}
c=""

infile=open("digit_words.txt","r")
outfile=open("digit_strings.txt","w")

l=infile.readlines()

for line in l:
    words=line.split()

    for nos in words:
        c+=str(di[nos])

    print(c, file=outfile)
    print("\n")
    c=""

infile.close()
outfile.close()
