Python program 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 tuple, a list comprehension, the ‘tuple’ method, and the ‘split’ method are used.

Example

Below is a demonstration of the same −

my_list = ["21$12", "33$24$48$69", "14$10$44"]

print("The list is :")
print(my_list)

key = "$"
print("The key is :")
print(key)

my_result = [tuple(int(element) for element in sub.split(key)) for sub in my_list]

print("The result is :")
print(my_result)

Output

The list is :
['21$12', '33$24$48$69', '14$10$44']
The key is :
$
The result is :
[(21, 12), (33, 24, 48, 69), (14, 10, 44)]

Explanation

• A list of string values is defined and is displayed on the console.

• A key value is defined and displayed on the console.

• A list comprehension is used to iterate over the list.

• It is split based on the ‘key’ that was previously defined.

• It is then converted into an integer and then to a list of tuple.

• This is assigned to a variable.

• This is displayed as output on the console.
