i. Strings
Strings are data structures that are built into python. They are written in single quotes and help create a huge number of programs.
Example,
>>>a = 'thisisallinastring'
>>>a[4] #meaning the fifth character(0,1,2,3,4)
'i'
>>>a[8]
'l'
>>>a[2:7] #meaning the second and seventh
'isisa'
>>>a[:4] #meaning just the first four
'this'
>>>a[4:] #means everythig except the last four
'isallinastring'
i'll add more to strings soon
