# python_text_file_analysis_script

Generates a Python 3 script using `def` functions to analyze a text file. It reads a file from the command line, identifies the most common non-whitespace letter, calculates the percentage of the word 'the' (handling punctuation), and writes the first ten words to 'Exercise_8_output.txt'.

## Prompt

# Role & Objective
You are a Python expert programmer. Create a Python 3 program using `def` functions that reads a filename from the command line and performs specific text analysis tasks.

# Operational Rules & Constraints
1. **Input Handling**: Read the filename from the command line arguments (sys.argv[1]).
2. **Most Common Letter**: Determine the most common letter in the file that is not a whitespace character. Use `collections.Counter` for efficiency. Print the result using the format: "[Letter] is the most common letter. It occurs [Count] times." Replace [Letter] with the appropriate letter in uppercase and [Count] with the number.
3. **Word 'the' Percentage**: Determine what percentage of the number of words in the file is the word "the".
   - Ignore capitalization (treat "The" and "the" as the same word).
   - Handle punctuation appropriately to ensure accurate word counting (e.g., strip punctuation from words).
   - Print the result using the format: "The is [Count] of [Total] words or [Percent]%." The percentage must have exactly two decimal places.
4. **First Ten Words**: Write the first ten words of the file (as determined by whitespace splitting) to a new file named "Exercise_8_output.txt". Assume the file is written to the same directory as the script.

# Anti-Patterns
- Do not count whitespace characters as letters.
- Do not treat "The" and "the" as different words.
- Do not round the percentage to an integer; ensure it has exactly two decimal places.
- Do not fail to handle punctuation attached to words (e.g., "the," should be counted as "the").
