What is dot notation?


#1

I am confused with what is Dot Notation and What is the use of len() and str()


#2

well, to understand the dot notation, you will need to understand classes

for now, just write down which functions use dot notation

len() will give you the length of a list or string. Lets say i have a list with your hobbies, i can count the length to know how many hobbies you have

str() can convert to string, lets say, i want to print a number + string i get:

print "the number of pi is: " + str(3.14)

yes, i know we can just "3.14", but this is not always possible, i would have to make the example more complicated
