Getting rid of Parentheses of Dict and unwanted words[Python]

Question

As working on a program using Dict in Python, I am getting a format other than required: the code is as follows:

a = {1:2,2:3,3:4,4:8}
print(a.values())

getting an output:

dict_values([2, 3, 4, 8])

here in the output, there is no requirement of "dict_values" and "{ [ ] }", How to remove these wanted things? Actually, I have tried striping but I am thinking of some professional functions to use.

I just want an output in the form of 2,3,4,8 simple in a iline — VIKAS RATHEE, Oct 06 '18 at 12:59
@zwer you need to cast the values to a `str` for `join` to work... — hiro protagonist, Oct 06 '18 at 13:01

You may use the * operator to unpack the sequence and print the values.

a = {1:2,2:3,3:4,4:8}
print(*a.values())
#2 3 4 8

You can also customize the separator and the end using the keyword arguments sep and end respectively in the call of the print function.
For example:

print(*a.values(), sep=',')

Add the `sep=','`to the `print` – progmatico Oct 06 '18 at 13:09

you could join the dict_values (which you need to cast to str) to a string:

', '.join(str(x) for x in a.values())
