what is the difference between
a1={‘1,2,3,4,5,6,7,8’}
and
a2={‘1’,‘2’,‘3’,‘4’,‘5’,‘6’,‘7’,‘8’}
Difference between lists formatted in different ways
hey @nsgcr7 , Welcome to the community
A dictionary is a combination of a key : value pairs.
SO , in the first case you have just a single key ( a single long string value) , without any values .
whereas in the second case you have multiple keys( small strings ), which also do not have any values.
This is the main difference now.
I hope you understand this.
