# count occurrences of text
total = text.count( substring )
# count( x ) needs at least one argument! --> it looks for x inside the string text and counts how many times x occurs
# it matches EXACTLY!! Cases matter!

from_index_i_on = text.count( substring, i )
# sometimes, you don't want to find all occurrences
# count() takes an optional 2nd argument = count( x, y )
# where y is the place you should start looking in the string, like from place 1 or 2 or 3 and so on.
# includes y and then to the end of the string

print( "text.count( substring ) =", total, "       # count all" )
print( "text.count( substring,", i, ") =", from_index_i_on, "    # count starting from index", i )

# spaces inside a string is a character --> counts towards the length and can be used with the count() function

# if you put '' in the substring --> this is an empty string
# metaphysical; in front/after each character is an empty string --> counts that
# kinda weird ; not something that's practically used


# parameter: things that define the arguments for each function --> tells the function what to expect when you use it
#   count(x) --> x is our parameter that tells the count() function to expect at least one argument
#       where x is actually a real value that we substitute in so that we can use the count() function
