We are familiar with word count features of word processors such as found in MS-Word. These will report the number of words and characters in a document. We would like to write a function that we can eventually use to analyze a python program. That is write a function that will return the number of non-white space characters, the number of variable/function names used in the program, and the number of characters used in the variable/function names. The rules for Python names are:
A. A variable name must start with a letter or the underscore character.
B. A variable name cannot start with a number.
C. A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
D. Variable names are case-sensitive (age, Age and AGE are three different variables)
Write a function python_word_count which when passed a string containing python code will return a tuple of total number of non-white space characters, number of characters found in the Python names, and the number of Python names found in the string. Write a main that will input a string and print the values returned by python_word_count together with the average length of the Python words. Ex:
def python_word_count(text):
Count of Python names: 3
Count of characters in Python names: 24
Average length of Python names: 8.0
Count of characters: 27
Ex 2:
if user_year % 4 == 0 and (user_year % _CENTURY != 0 or user_year % 400 == 0):
Count of Python names: 7
Count of characters in Python names: 42
Average length of Python names: 6.0
Count of characters: 61
Note: For simplicity, we will ignore the the fact that names within strings or in comments are not really Python names. Thus words inside quotes or in a comment will be counted as Python names. For consideration; what would be needed to exclude such words being counted.
Furthermore Python keywords will be considered to be Python names.
All in Python please =)
