Python – To convert a list of strings with a delimiter to a list of tuple
When it is required to convert a list of strings with a delimiter to a list of tuples, a K value is set, and list comprehension along with the ‘split’ method is used.
Example
Below is a demonstration of the same −
my_list = ["33-22", "13-44-81-39", "42-10-42", "36-56-90", "34-77-91"]
print("The list is : " )
print(my_list)
print("The sorted list is ")
my_list.sort()
print(my_list)
K = "-"
print("The value of K is ")
print(K)
my_result = [tuple(int(element) for element in sub.split(K)) for sub in my_list]
print("The resultant list is : ")
print(my_result)Output
The list is : ['33-22', '13-44-81-39', '42-10-42', '36-56-90', '34-77-91'] The sorted list is ['13-44-81-39', '33-22', '34-77-91', '36-56-90', '42-10-42'] The value of K is - The resultant list is : [(13, 44, 81, 39), (33, 22), (34, 77, 91), (36, 56, 90), (42, 10, 42)]
Explanation
A list of strings is defined and is displayed on the console.
The list is sorted using a sort method and is displayed on the console.
The value for K is defined and displayed in the console.
A list comprehension is used to iterate over the list, and the value is split and converted to an integer and then to a tuple.
This is assigned to a result.
This is displayed as output on the console.
