how to split the list and get the last value in python

Question

I have a list in this format. input: ['210#680#200#553','211#680#230#554','211#682#210#557']

I want to grep the last number values based on the delimiter value of each element in my list. my expected output is

output = ['553','554','557']

How to use python code to get this logic?

Answer 1

This answer certainly isn't as concise as the other one, but hopefully it allows you to understand the process more clearly.

lst =  ['210#680#200#553','211#680#230#554','211#682#210#557']
return_list = []

for string in lst:
    last_num = string.split("#")[-1] #Splits string and gets last element
    return_list.append(last_num) #Adds last element to return_list
    
print(return_list) #Prints ['553', '554', '557']

Answer 2

An idea is to look for what is called list comprehension , which is a way to easily process each element of a list in python. The result will be a new list whose i-th element will correspond to the result of the aforementioned processing of the i-th element of the initial list.

In your problem, you could use something like:

output = [x.split("#")[-1] for x in input_list]

Answer 3

output = [w.split("#")[-1] for w in input]
