Part 1
replace 4 most common letters in the text with 4 most common letters in the English language ‘e’,’t’,’o’,’r’.
in example: 'a' is most common - replace it with 'e', and 'e' with 'a'
in example: abcd most common chars in text:  a <-> e, b <-> t, c <-> o, d <-> r

Create a function replace_common_occurences(str) -> replaced_dict - that will include the most common letters and their replacements.
The function needs to find the most common chars (count occurences)
The function will receive a text as a string and will return the relevant dictionary - replaced_dict
{'a': 'e', 'c': 'o', 'b': 't', 'e': 'a', 'd': 'r', 'o': 'c', 'r': 'd', 't': 'b'}

1. The dictionary will include only letters that were changed.
2. include only letters - not numbers, spaces, etc.
3. code must be case insensitive - dictionary only lower case
4. check:
    a. There are at least four different letters in your text
    b. for for every popular letter - there is no letter that appears the same number of times.
    c. the most popular letters are not 'e', 't', 'o', 'r'
"""

"""
Part 2
1. Write a function replace_chars_in_text(text to change, replaced_dict) -> changed str
2. The function will iterate over the str and for each char
   if there is a replaced_dict[key] - replace with the value, otherwise do not change.
3. Example: str             = ///bha Taa3add, bha Tdaer, enr b7ha Fdcccccbbb
            replaced_dict   =  {'a': 'e', 'c': 'o', 'b': 't', 'e': 'a', 'd': 'r', 'o': 'c', 'r': 'd', 't': 'b'} 
            replaced_str    =  ///the bee3err, the bread, and t7he frooooottt
"""

"""
Part 3
Create a function: decode_text(path to encrypted text file) to update the message text file
call:
    1. replace_common_occurences(str) -> replaced_dict
    2. replace_chars_in_text(text to change, replaced_dict) -> changed str
add to message.txt file: 'the encryption for the above text is:' ....decrypted text....
create another text file - results.txt - include only the decrypted results. 
notes: common chars should be done over all text file, not line by line. 
ignore \n.
"""

"""
Part 4
Create a function find_longest_word(path to results.txt) -> list of longest words. 
return the longest word in result.txt file (decrypted text) - count only alphabetical chars.
Removing all non alpha chars - import re, regex=re.compile("[^a-zA-Z]") list[i]=regex.sub(", your string)
Create a function count_num_of_lines(path to results.txt) -> num of lines.

main()
1. decrypt message - part 1,2,3
2. write to the original message (append) the first value of the longest words list return from  find_longest_word(path to results.txt) 
   times the number of lines in results.txt file. 
   Example:  Your longest word is "BOOBOBA", The number of lines is 2.
   Add to original message.txt - BOOBOBA BOOBOBA

def ListOfLists(list):
     '''
     This function receives a list, which can contain elements that are themselves lists and
     returns those items separately in a single list.
     If the parameter is not of type list, it must return null.
     Receive an argument:
         list: The list that can contain other lists and is converted to a
         list of unique or non-iterable elements.
     Ex:
         ListOfLists([1,2,['a','b'],[10]]) should return [1,2,'a','b',10]
         ListOfLists(108) should return null.
         ListOfLists([[1,2,[3]],[4]]) should return [1,2,3,4]
