我如何将原诗转换成已转换的诗

它应该将cubits转换为feet

原诗：

"So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide and 30 cubits high. (Genesis 6:14-15)"

转换诗：

"So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be 450 feet long, 75 feet wide and 45 feet high. (Genesis 6:14-15)"

Answer 1

记下每个单词，然后检查值

差不多

conversion_factor = 1.5
words = verse.split()
for i, word in enumerate(words):
    if i < len(words)-1 and words[i+1] == 'cubits':
        amount = int(word)
        word = int(amount * conversion_factor)
    if word == 'cubits':
        word = 'feet'
    print(word, end = ' ')

输出

"So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be 450 feet long, 75 feet wide and 45 feet high. (Genesis 6:14-15)"

Answer 2

您可以匹配正则表达式，并使用替换函数调整单位（并更改单位名称）

import re

r = re.compile("(\d+) cubits")

s = "So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be 300 cubits long, 50 cubits wide and 30 cubits high. (Genesis 6:14-15)"

print(r.sub(lambda m : "{} feet".format(int(float(m.group(1))*1.5)),s))

结果:

So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out. This is how you are to build it: The ark is to be 450 feet long, 75 feet wide and 45 feet high. (Genesis 6:14-15)

当正则表达式匹配后跟“cubits”的数字时，它调用lambda回调，解析该数字，乘以1.5，转换回整数，并用新的单位重新格式化输出

这将不得不微调为1英尺，并可以使用转换字典，如果有更多的单位转换
