Design a program named CharDistribution.py$,$ within this program, implements functions as specified below: charFrequency$($aString$,$ aChar$)-$ this function counts number of times the char aChar appears in aString. For example, calling charFrequency$("$Hello hanson", $\text{'}$h$\text{'})$ should return $2,$ because char $\text{'}$h$\text{'}$ appears in the String twice. We donot make difference between upper and lower cases. allCharFrequency$($aString$)-($it is OK if you have already implemented : allCharFrequency$($aString$,$ aChar$))-$ this function counts number of times of each of $26$ alphabetic letters appears in aString and return the frequencies as a $26-$element list. Again, we don't make differenec between lower and upper cases. printFrequency$($fre$),$ where fre is the frequency of $26$ alphabetic letters. This function will print the frequency in the format as follows: A: $[10]$ # lette a$/$A appears $10$ times B: $[2]$ # letter b$/$B appears $2$ times $...$
