Trying to create a list & tuple from User Input

Question

For e.g. user input:

4,7,5,33,2,8

should give output like this:

['4', '7', '5', '33', '2', '8'] ('4', '7', '5', '33', '2', '8')

So far i have this:

x = input()
z = x.split()
y = tuple(z)
print(z, y)

why there is extra , in the end of tuple?

Input: 12,56,48,86 Output: ['12,56,48,86'] ('12,56,48,86',) why there is extra , in the end of tuple? — Dhruv Nautiyal

It represents that it is a tuple. ('...') is just wrapped str. ('...',) is tuple of str. — Boseong Choi

And x.split() is splitting the string by white spaces. You should use x.split(','). — Boseong Choi

This ('12,56,48,86',) is tuple containing one element....this ('4', '7', '5', '33', '2', '8') is tuple containing 5 elements. — Ch3steR

You should do

z = x.split(",")

instead of

z = x.split()

The extra comma is because the string you tried to split is not what you are expecting after the split. Since the split was performed on space with x.split() and string does not have white space so after the step the string is still a single string and then list and tuple just wrap the string and that's where the extra comma is coming from. Example tuple('a') == ('a',)

x.split(',') will create a list separate by comma and will fetch you expected results
