Resolved: line 107- 9:25- the command
I read all the confusions posted in this lesson about the line 107
however my question is about the necessity of typing "0" in "letter_count.get(letter,0). Isn't it by default zero if we do not write it? as far as I learned through the lesson the general command is " letter_count.get(keys or value)" and I do not really understand what does the digit after " ," really imply?if it does imply as an index, it has to be zero by default , if we do not type it.
that is the value parameter (it is optional), this method contains two parameters, the keyname and value parameter.
|keyname||Required. The keyname of the item you want to return the value from|
|value||Optional. A value to return if the specified key does not exist.
Default value None
