Python Converting List and tuples using str() function

[Taylor_1989]

TL;DR Summary

I am slightly confused to why using the str() on a tuple and list produces a length greater than a a defined string when comparing lengths

I am currently working my way through some w3schools python exercise on tuples and lists etc and one question was to write a program to converted a tuple to a string.

Now originally I used the str() function on the tuple and printed the result. I then used the string in a for loop for a further question and realized that the tuples and lists were printing additional terms compared when just defining a string using ' '.

As can be seen from my code below

t =(1,2,3,4,5)
L =[1,2,3,4,5]

string = '1,2,3,4,5'

t = str(t)
L = str(L)

length = len(t)
length1 = len(L)
length2 = len(string)

print(length)
print(length1)
print(length2)

Output
15
15
9

My question why is this, why is there 15 for the list and the tuple yet 9 for the string? Where is the additional six count coming from in the tuple and list?

Try printing the actual strings you made from the tuple and the list and counting the characters. In other words:

print(t)
print(L)

Ah I see the tuple and lists output spaces, thank you.

the tuple and lists output spaces

And the delimiters as well, yes.
