1. char_analysis.py (40 points)

Write a program that reads the file’s contents and determine the following:

1. The number of Uppercase letters in the file
2. The number of Lowercase letters in the file
3. The number of digits in the file
4. The number of whitespace characters in the file

HINTS:

Define main():

Declare Local variables

Open file text2.txt for reading. Use ‘text2.txt’ file available under the Modules section in Canvas.

Use ‘set’ method to find the unique words in the file and store each of them as an element of the set.
