[英]how to match a string from a list of strings and ignoring regex special characters?
[英]How to find string from a list of strings with a specific list of characters?
我有一个给定的字符串列表和一个字符列表,我想检查包含特定字符的字符串。 这是一个例子:
Dictionary = ["Hello", "Hi"]
Character = ['e','i']
它必须返回一个“Hello”其他空列表
我正在比较一个字符列表和一个字符串列表,但它给了我一个类型错误。
Dictionary = ["Hello", "Hi"]
Character = ['e']
emptystring = ""
def findwords(dictionary,character):
for i in dictionary,character:
for j in dictionary:
if character[i] == dictionary[i][j]:
return dictionary[i]
else:
j+=1
i+=1
return emptystring
k = findwords(Dictionary,Character)
k
TypeError Traceback (most recent call last)
<ipython-input-49-996912330841> in <module>
----> 1 k = findwords(Dictionary,Character)
2 k
<ipython-input-48-9e9498ec1a51> in findwords(dictionary, character)
5 for i in dictionary,character:
6 for j in dictionary:
----> 7 if str(character[i]) == str(dictionary[i][j]):
8 return str(dictionary[i])
9 else:
TypeError: list indices must be integers or slices, not list
这可能会稍微清理你的代码,我认为这是你想要的......
Dictionary = ["Hello", "Hi"]
Character = ["e"]
def findwords(dictionary, character):
for i in dictionary:
if any(j in i for j in character):
return i
return ""
对于所有比赛:
def findwords(dictionary, character):
matches = []
for i in dictionary:
if any(j in i for j in character):
matches.append(i)
if matches:
return ",".join(matches)
else:
return ""
它将查看子字符串中的任何内容是否与您的单词匹配。 如果是,请返回单词,否则""
findwords([“Hello”,“Hi”],[“e”])
'你好'
findwords([“Hello”,“Hi”],[“k”])
“”
对于你的问题:
TypeError:list indices必须是整数或切片,而不是list
for i in dictionary,character: <-- I will be list ['Hello', 'Hi']
for j in dictionary:
if character[i] == dictionary[i][j]: <---- you can't do character[i] where i is ['Hello', 'Hi']
检查一下。
Dictionary = ["Hello", "Hi"]
Character = ['e']
def findwords(dictionary,character):
tmp = ""
for i in dictionary:
#convert string to char list
str_arr = list(i)
for j in character:
#if char is in char list then save it in tmp variable
#if you want multiple values then use array instead of tmp
if j in str_arr:
tmp = i
return tmp
k = findwords(Dictionary,Character)
print(k)
