Write a function named count_letters that takes as a parameter a string and returns a dictionary that tabulates how many of each letter is in that string. the string can contain characters other than letters, but only the letters should be counted. the string could even be the empty string. lower-case and upper-case versions of a letter should be part of the same count. the keys of the dictionary should be the upper-case letters. if a letter does not appear in the string, then it would not get added to the dictionary. the dict and count function may not be used. for example, if the string is```"aabb"```then the dictionary that is returned should contain these key-value pairs: ```{'a': 2, 'b': 2}so far i am stuck at(which is not working correctly when given to capitalized values, ex "aa" returns 1): def count_letters(string): letter_dic = { } for letter in string: if letter in letter_dic: letter_dic[letter] = +1 else: letter_dic[letter] = 1 return letter_dic

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.

This printout will be      akes======in java, somestring.substring(a,b) will return a portion of somestring, including index a and up to but not including index b.in java, string indexes start from 0. the very first character has an index of 0.for  shakespeare, we have    "shakespeare".substring(2,6); gets us "akes"
