Given Tuples, convert them to dictionary with key being concatenated string.
Input : test_list = [((“gfg”, “is”, “best”), 10), ((“gfg”, “for”, “cs”), 15)]
Output : {‘gfg is best’: 10, ‘gfg for cs’: 15}
Explanation : Tuple strings concatenated as strings.Input : test_list = [((“gfg”, “is”, “best”), 10)]
Output : {‘gfg is best’: 10}
Explanation : Tuple strings concatenated as strings.
Method #1 : Using loop + join()
In this, we perform the task of concatenation for dictionary key using join() and loop is used to render the required dictionary.
Python3
# Python3 code to demonstrate working of # Concatenate Tuple to Dictionary Key # Using loop + join() # initializing list test_list = [(("gfg", "is", "best"), 10), (("gfg", "good"), 1), (("gfg", "for", "cs"), 15)] # printing original list print("The original list is : " + str(test_list)) res = {} for sub in test_list: # joining for making key res[" ".join(sub[0])] = sub[1] # printing result print("The computed Dictionary : " + str(res)) |
The original list is : [(('gfg', 'is', 'best'), 10), (('gfg', 'good'), 1), (('gfg', 'for', 'cs'), 15)]
The computed Dictionary : {'gfg is best': 10, 'gfg good': 1, 'gfg for cs': 15}
Method #2 : Using dictionary comprehension
This is shorthand to above method, similar functionality, just one-liner on paper for compact solution.

# Python3 code to demonstrate working of # Concatenate Tuple to Dictionary Key # Using dictionary comprehension # initializing list test_list = [(("gfg", "is", "best"), 10), (("gfg", "good"), 1), (("gfg", "for", "cs"), 15)] # printing original list print("The original list is : " + str(test_list)) # one liner to solve problem res = {' '.join(key): val for key, val in test_list} # printing result print("The computed Dictionary : " + str(res)) |
The original list is : [(('gfg', 'is', 'best'), 10), (('gfg', 'good'), 1), (('gfg', 'for', 'cs'), 15)]
The computed Dictionary : {'gfg is best': 10, 'gfg good': 1, 'gfg for cs': 15}
