Text Analyzer

Phase 1 - Basic text statistics

Create a Python script that reads a text file and computes the number of words and sentences, as well as identifies unique phone numbers and CNPs.

• Input a text file
• Count total words and sentences
• Detect unique phone numbers (starting with 07) and CNPs

Functional result: Script displays correct word and sentence counts and lists unique phone numbers and CNPs found.

Phase 2 - Letter frequency analysis

Extend the script to compute case-insensitive letter statistics and the percentage of each letter relative to the total letters in the text.

• Count occurrences of each letter (ignore case)
• Calculate the percentage of each letter in total letters
• Display the results alongside previously computed statistics

Functional result: Script outputs a frequency table of letters with counts and percentages, together with word, sentence, phone, and CNP statistics.
