please be aware, im new to python:
i'm trying to create a defined function that can convert a list into a string, and allows me to put a separator in. The separator has to be ', '.
My current thought process is to add each item from a list to an empty string variable, and then I'm trying to make use of the range function to add a separator in. I'm only wanting to use str() and range().

```
def list2Str(lisConv, sep = ', '):
    var = ''
    for i in lisConv:
        var = var + str(i)
        #test line
        print(var, "test line")
    var1 = int(var)
    for a in range(var1):
        print(str(var1)[a],  sep = ', ')

list1 = [2,0,1,6]        

result = list2Str(list1, ', ')
print(result)

```
