What is dot notation?


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


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


Thanks the reply was very helpful!
