Python - 提取相似的键值

给定一个字典，从相似的键中提取所有值，即包含所有相似的字符，只是混在一起形成彼此。

Input : test_dict = {‘gfg’ : 5, ‘ggf’ : 19, ‘gffg’ : 9, ‘gff’ : 3, ‘fgg’ : 3}, tst_wrd = ‘fgg’ 
Output : [5, 19, 3] 
Explanation : gfg, ggf and fgg have values, 5, 19 and 3.

Input : test_dict = {‘gfg’ : 5, ‘gffg’ : 9, ‘gff’ : 3, ‘fgg’ : 3}, tst_wrd = ‘fgg’ 
Output : [5, 3] 
Explanation : gfg and fgg have values, 5 and 3. 

方法 #1：使用 sorted() + 循环

在此，我们将排序后的键与目标键进行比较，将具有正确顺序的相似元素，并且可以检查是否相等。一旦匹配，它们的值就会被提取出来。

# Python3 code to demonstrate working of
# Extract Similar Key Values
# Using loop + sorted()
  
# initializing dictionary
test_dict = {'gfg': 5, 'ggf': 19, 'gffg': 9, 'gff': 3, 'fgg': 3}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# initializing word
tst_wrd = 'fgg'
  
res = []
for key, val in test_dict.items():
  
    # sorted to get similar key order
    if ''.join(list(sorted(key))) == tst_wrd:
        res.append(val)
  
# printing result
print("The extracted keys : " + str(res))

输出：

The original dictionary is : {‘gfg’: 5, ‘ggf’: 19, ‘gffg’: 9, ‘gff’: 3, ‘fgg’: 3}
The extracted keys : [5, 19, 3]

方法 #2：使用列表理解 + sorted()

在这里，我们执行与上面类似的任务，只需使用sorted()和列表推导使用速记来执行。

# initializing dictionary
test_dict = {'gfg': 5, 'ggf': 19, 'gffg': 9, 'gff': 3, 'fgg': 3}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# initializing word
tst_wrd = 'fgg'
  
# one-liner to solve this
res = [val for key, val in test_dict.items(
) if ''.join(list(sorted(key))) == tst_wrd]
  
# printing result
print("The extracted keys : " + str(res))

输出：

The original dictionary is : {‘gfg’: 5, ‘ggf’: 19, ‘gffg’: 9, ‘gff’: 3, ‘fgg’: 3}
The extracted keys : [5, 19, 3]
