#A string is a type of data. There are many data types. It can be manipulated.
#It can be storerd as a variable
myString = "Hello world"
#WE can print it:
print(myString)
#You can append it to arraY:
myArr = []
myArr.append(myString)
#You can find the index of a character in a string:
H = myString[0]
#You can use methods on it:
lowercase = myString.lower()
#You can convert it into a integer provided it is a numerical string
myInt = int(myString)
