【问题描述】：

我在表单中有一个字典项

 {"value for money": ["rescheduled", "cost", "low", "high", "simplicity", "booking", "price-performance", "satisfied", "satisfaction", "pricing", "prices"]}

我需要检查“I love simple”之类的字符串是否包含这本词典中的任何单词。

不知道如何为此定义代码。

【问题讨论】：

基本for循环可以解决这个问题，你能详细说明问题吗？

【解决方案1】：

试试：

mydict =  {"value for money": ["rescheduled", "cost", "low", "high", "simplicity", "booking", "price-performance", "satisfied", "satisfaction", "pricing", "prices"]}
mystring = "I love simplicity"
if any((word in mystring) for word in mydict["value for money"]):
    print("Found one.")

【解决方案2】：

d={"value for money": ["rescheduled", "cost", "low", "high", "simplicity", "booking", "price-performance", "satisfied", "satisfaction", "pricing", "prices"]}
s="I love simplicity" 

for w in s.split(' '):
  if w in d["value for money"]:
    print (w," is in value for money")

【解决方案3】：

如果您的字典仅包含“物有所值”键，或者您只需要该键的值，并且您只需要知道输入字符串中的任何单词是否在这些值中：

def is_in_dict(string, dictionary):
    for word in string.split():
        if word in dictionary['value for money']:
            return True
    return False

如果您的 dict 有许多其他键并且您需要全部检查：

def is_in_dict(string, dictionary):
    for word in string.split():
        for values in dictionary.values():
            if word in values:
                return True
    return False

【解决方案4】：

如果你想使用循环：

string = 'I love simplicity'
dictionary =  {"value for money": ["rescheduled", "cost", "low", "high", "simplicity", "booking", "price-performance", "satisfied", "satisfaction", "pricing", "prices"]}

for word in dictionary['value for money']:
    if word in string:
        print(word)

如果你想使用生成器：

[word for word in dictionary['value for money'] if word in string]
