Python – Concatenate Tuple to Dictionary Key
When it is required to concatenate tuple to a dictionary key, a list comprehension and the ‘join’ attribute are used.
Example
Below is a demonstration of the same −
my_list = [(("pyt", "is", "best"), 10), (("pyt", "cool"), 1), (("pyt", "is", "fun"), 15)]
print("The list is :")
print(my_list)
my_result = {}
for sub_list in my_list:
my_result[" ".join(sub_list[0])] = sub_list[1]
print("The result is :")
print(my_result)Output
The list is :
[(('pyt', 'is', 'best'), 10), (('pyt', 'cool'), 1), (('pyt', 'is', 'fun'), 15)]
The result is :
{'pyt is best': 10, 'pyt cool': 1, 'pyt is fun': 15}Explanation
A list of tuple is defined and is displayed on the console.
An empty dictionary is created.
The list is iterated over, and the list comprehension is used to remove spaces.
This is the output that is displayed on the console.
