Given List of elements, convert it to delimiter separated String.
Input : test_list = [7, “Gfg”, “best”, 9], delim = “*”
Output : 7*Gfg*best*9*
Explanation : All elements are concatenated with “*” as joiner.Input : test_list = [7, “Gfg”, “best”, 9], delim = “#”
Output : 7#Gfg#best#9#
Explanation : All elements are concatenated with “#” as joiner.
Method #1 : Using loop + str()
This is one of the ways in which this task can be performed. In this, we run a loop to add delimiter at end of each element, after converting each element to string.
Python3
# Python3 code to demonstrate working of # Convert List to delimiter separated String # Using loop + str() # initializing list test_list = [7, "Gfg", 8, "is", "best", 9] # printing original list print("The original list is : " + str(test_list)) # initializing delim delim = "*" res = '' # using loop to add string followed by delim for ele in test_list: res = res + str(ele) + delim # printing result print("The resultant string : " + str(res)) |
The original list is : [7, 'Gfg', 8, 'is', 'best', 9] The resultant string : 7*Gfg*8*is*best*9*
Method #2 : Using join() + str()
This is yet another way in which this task can be performed. In this we perform the task of joining each element by delim using join() and conversion to string is done using str().
Python3
# Python3 code to demonstrate working of # Convert List to delimiter separated String # Using join() + str() # initializing list test_list = [7, "Gfg", 8, "is", "best", 9] # printing original list print("The original list is : " + str(test_list)) # initializing delim delim = "*" # using map to convert each element to string temp = list(map(str, test_list)) # join() used to join with delimiter res = delim.join(temp) # printing result print("The resultant string : " + str(res)) |
The original list is : [7, 'Gfg', 8, 'is', 'best', 9] The resultant string : 7*Gfg*8*is*best*9
