Python Data Structure Srings Part 2/2

Strings part 2
Strings are a sequence of characters, we define strings using quotation marks.
Strings can be transverse using the loop.
A subset of strings can be taken using slicing operators.
Strings are immutable.
in operator can be used with strings to see if this string or characters is a subset of the given string.
Strings comparison can be used in if condition commands. The comparison is based on their ASCII code.

In Part 2 we will discuss the methods for string objects, like upper, lower and find, strip and stars with, format and fstring.
lower and upper are the methods to convert a string object to lower and upper case respectively,
find is the method which gives index where a certain substring's fist instance appears in the string.
the strip is a method to remove stirng's extra spaces. starswith is the method to find either a line is starting from a certain substring. format and fstring methods are to display string in the desired format.
