Question

假设我的词典包含

{'one': '1','two': '2', ..., 'hundred': '100'}

我的清单包含

[['for 30']['for thirty']]

我想将列表中的字符串拆分为：

[for],[30] and [for],[thirty]

然后我想使用'thirty'与字典中的相应条目进行比较，并获得'30'作为输出。

import csv

reader = csv.reader(open('dict.csv', 'r'))
d = {}
for row in reader:
   k, v = row
   d[k] = v

with open('test_term.csv', 'rb') as f:
    reader = csv.reader(f)
    your_list = list(reader)

欢迎使用Python！您应该阅读一些基础知识，例如如何声明列表和字典。

我猜你要做的是：

# this is how you format a list
pair_list = ['for 30', 'for thirty', 'for 1', 'for two']
# this is how you format a dict
resolve_dict = {'one': '1', 'thirty': '30', 'hundred': '100'}

# iterate the list two strings at a time
for idx in xrange(len(pair_list)):
    # example in comments
    # pairs[idx] == 'for 30'
    splitted = pair_list[idx].split(' ')
    # splitted == ['for', '30']
    number = splitted[1]
    # number == '30'

    # pairs[idx + 1] == 'for thirty'
    splitted = pair_list[idx + 1].split(' ')
    # splitted == ['for', 'thirty']
    word = splitted[1]
    # word == 'thirty'

    # comparison
    if resolve_dict[word] == number:
        print 'hurray?'

如何拆分列表中的字符串并使用输出与字典进行比较？
